Safety Instructions These safety instructions are intended to prevent a hazardous situation and/or equipment damage. These instructions indicate the level of potential hazard by a label of "Caution", "" or "Danger". To ensure safety, be sure to observe ISO 44 Note 1), JIS 370 Note 2) and other safety practices. Caution : Operator error could result in injury or equipment damage. : Operator error could result in serious injury or loss of life. Danger : In extreme conditions, there is a possible result of serious injury or loss of life. Note 1) ISO 44: Pneumatic fluid power -- Recommendations for the application of equipment to transmission and control systems. Note 2) JIS 370: General Rules for Pneumatic Equipment 1. The compatibility of pneumatic equipment is the responsibility of the person who designs the pneumatic system or decides its specifications. Since the products specified here are used in various operating conditions, their compatibility for the specific pneumatic system must be based on specifications or after analysis and/or tests to meet your specific requirements. 2. Only trained personnel should operate pneumatically operated machinery and equipment. Compressed air can be dangerous if an operator is unfamiliar with it. ssembly, handling or repair of pneumatic systems should be performed by trained and experienced operators. 3. Do not service machinery/equipment or attempt to remove components until safety is confirmed. 1. Inspection and maintenance of machinery/equipment should only be performed after confirmation of safe locked-out control positions. 2. When equipment is to be removed, confirm the safety process as mentioned above. Cut the supply pressure for this equipment and exhaust all residual compressed air in the system. 3. efore machinery/equipment is restarted, take measures to prevent shooting-out of cylinder piston rod, etc. (leed air into the system gradually to create back pressure.) 4. Contact SMC if the product is to be used in any of the following conditions: 1. Conditions and environments beyond the given specifications, or if product is used outdoors. 2. Installation on equipment in conjunction with atomic energy, railway, air navigation, vehicles, medical equipment, food and beverages, recreation equipment, emergency stop circuits, press applications, or safety equipment. 3. n application which has the possibility of having negative effects on people, property, or animals, requiring special safety analysis. 23
ctuator Precautions 1 e sure to read before handling. Design 1. There is a danger of sudden action by air cylinders if sliding parts of machinery are twisted, etc., and changes in forces occur. In such cases, human injury may occur; e.g., by catching hands or feet in the machinery, or damage to the machinery itself may occur. Therefore, the machine should be designed to avoid such dangers. 2. ttach a protective cover to minimize the risk of human injury. If a driven object and moving parts of a cylinder pose a danger of human injury, design the structure to avoid contact with the human body. 3. Securely tighten all stationary parts and connected parts so that they will not become loose. Especially when a cylinder operates with high frequency or is installed where there is a lot of vibration, ensure that all parts remain secure. 4. deceleration circuit or shock absorber, etc., may be required. When a driven object is operated at high speed or the load is heavy, a cylinder s cushion will not be sufficient to absorb the impact. Install a deceleration circuit to reduce the speed before cushioning, or install an external shock absorber to relieve the impact. In this case, the rigidity of the machinery should also be examined.. Consider a possible drop in circuit pressure due to a power outage, etc. When a cylinder is used in a clamping mechanism, there is a danger of work pieces dropping if there is a decrease in clamping force due to a drop in circuit pressure caused by a power outage, etc. Therefore, safety equipment should be installed to prevent damage to machinery and/or human injury. Suspension mechanisms and lifting devices also require consideration for drop prevention. 6. Consider a possible loss of power source. Measures should be taken to protect against human injury and equipment damage in the event that there is a loss of power to equipment controlled by air pressure, electricity or hydraulics, etc. 7. Design circuitry to prevent sudden lurching of driven objects. When a cylinder is driven by an exhaust center type directional control valve or when starting up after residual pressure is exhausted from the circuit, etc., the piston and its driven object will lurch at high speed if pressure is applied to one side of the cylinder because of the absence of air pressure inside the cylinder. Therefore, equipment should be selected and circuits designed to prevent sudden lurching because, there is a danger of human injury and/or damage to equipment when this occurs.. Consider emergency stops. Design so that human injury and/or damage to machinery and equipment will not be caused when machinery is stopped by a safety device under abnormal conditions, a power outage or a manual emergency stop.. Consider the action when operation is restarted after an emergency stop or abnormal stop. Design the machinery so that human injury or equipment damage will not occur upon restart of operation. When the cylinder has to be reset at the starting position, install safe manual control equipment. Selection 1. Confirm the specifications. The products advertised in this catalog are designed according to use in industrial compressed air systems. If the products are used in conditions where pressure, temperature, etc., are out of specification, damage and/or malfunction may be caused. Do not use in these conditions. (Refer to specifications.) Consult SMC if you use a fluid other than compressed air. Caution 1. Operate within the limits of the maximum usable stroke. The piston rod will be damaged if operated beyond the maximum stroke. Refer to the air cylinder model selection procedures for the maximum usable stroke. 2. Operate the piston within a such that collision damage will not occur at the stroke end. Operate within a such that damage will not occur when the piston having inertial force stops by striking the cover at the stroke end. Refer to the cylinder model selection procedure for the within which damage will not occur. 3. Use a speed controller to adjust the cylinder drive speed, gradually increasing from a low speed to the desired speed setting. Caution Mounting 1. e certain to align the rod axis with the load and direction of movement when connecting. When not properly aligned, twisting may occur in the rod and tube, and damage may be caused due to wear on the inner tube surface, bushings, rod surface and seals, etc. 2. When an external guide is used, connect the rod end and the load in such a way that there is no interference at any point within the stroke. 3. Do not scratch or gouge the sliding parts of the cylinder tube or piston rod, etc., by striking or grasping them with other objects. Cylinder bores are manufactured to precise tolerances, so that even a slight deformation may cause malfunction. lso, scratches or gouges, etc., in the piston rod may lead to damaged seals and cause air leakage. 4. Prevent the seizure of rotating parts. Prevent the seizure of rotating parts (pins, etc.) by applying grease.. Do not use until you can verify that equipment can operate properly. Following mounting, maintenance or conversions, verify correct mounting by suitable function and leakage tests after compressed air and power are connected 6. Instruction manual The product should be mounted and operated after thoroughly reading the manual and understanding its contents. Keep the instruction manual where it can be referred to as needed. 24
ctuator Precautions 2 e sure to read before handling. Piping Caution 1. Preparation before piping efore piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe. 2. Wrapping of pipe tape When screwing together pipes and fittings, etc., be certain that chips from the pipe threads and sealing material do not get inside the piping. lso, when pipe tape is used, leave 1. to 2 thread ridges exposed at the end of the threads. Expose approx. 2 threads Wrapping direction Pipe tape 1. Use clean air. Do not use compressed air that includes chemicals, synthetic oils containing organic solvents, salt or corrosive gases, etc., as it can cause damage or malfunction. 2. Install an after-cooler, air dryer or water separator, etc. ir that includes excessive drainage may cause malfunction of valves and other pneumatic equipment. To prevent this, install an after-cooler, air dryer or water separator, etc. 3. Use the product within the specified of fluid and ambient temperature. Take measures to prevent freezing, since moisture in circuits can be frozen below C, and this may cause damage to seals and lead to malfunction. Refer to SMC s ir Cleaning Equipment catalog for further details on compressed air quality. Caution ir Supply 1. Install air filters. Install air filters at the upstream side of valves. The filtration degree should be µm or finer. 2. Install an after-cooler, air dryer or water separator, etc. ir that includes excessive drainage may cause malfunction of valves and other pneumatic equipment. To prevent this, install an after-cooler, air dryer or water separator, etc. 3. Use the product within the specified of fluid and ambient temperature. Take measures to prevent freezing, since moisture in circuits can be frozen below C, and this may cause damage to seals and lead to malfunction. Refer to SMC s ir Cleaning Equipment catalog for further details on compressed air quality. Operating Environment 1. Do not use in environments where there is a danger of corrosion. 2. In dusty locations or where water, oil, etc., splash on the equipment, take suitable measures to protect rod. 3. When using auto switches, do not operate in an environment with strong magnetic fields. Maintenance 1. Perform maintenance according to the procedure indicated in the instruction manual. If handled improperly, malfunction and damage of machinery or equipment may occur. 2. Removal of equipment, and supply/exhaust of compressed air. When equipment is removed, first check measures to prevent dropping of driven objects and run-away of equipment, etc. Then cut off the supply pressure and electric power, and exhaust all compressed air from the system. When machinery is restarted, proceed with caution after confirming measures to prevent cylinder lurching. Caution 1. Drain flushing Remove drainage from air filters regularly. (Refer to specifications.) Caution ubrication 1. ubrication of non-lube type cylinder The cylinder is lubricated at the factory and can be used without any further lubrication.
uto Switch Precautions 1 e sure to read before handling. 1. Confirm the specifications. Read the specifications carefully and use this product appropriately. The product may be damaged or malfunction if it is used outside the of specifications for load current, voltage, temperature or impact. 2. Take precautions when multiple cylinders are used close together. When multiple auto switch cylinders are used in close proximity, magnetic field interference may cause the switches to malfunction. Maintain a minimum cylinder separation of mm. 3. Pay attention to the length of time that a switch is ON at an intermediate stroke position. When an auto switch is placed at an intermediate position of the stroke and a load is driven at the time the piston passes, the auto switch will operate, but if the speed is too great the operating time will be shortened and the load may not operate properly. The maximum detectable piston speed is: uto switch operating V (mm/s) = oad operating time (ms) x 0 In case of high piston speed, the operating time of the load can be extended by using an auto switch (D-F7NT) with built-in OFF delay timer (approx. 0ms). 4. Keep wiring as short as possible. <Reed switches> s the length of the wiring to a load gets longer, the rush current at switching ON becomes greater, and this may shorten the product s life. (The switch will stay ON all the time.) Use a contact protection box when the wire length is m or longer. <Solid state switches> lthough wire length should not affect switch function, use a wire m or shorter.. Pay attention to the internal voltage drop of the switch. <Reed switches> 1) Switches with an indicator light (except D-76H/6/6V) If auto switches are connected in series as shown below, take note that there will be a large voltage drop because of internal resistance in the light emitting diodes. (Refer to internal voltage drop in the auto switch specifications.) [The voltage drop will be n times larger when n auto switches are connected.] Even though an auto switch operates normally, the load may not operate. Design and Selection In the same way, when operating below a specified voltage, although an auto switch may operate normally, the load may not operate. Therefore, the formula below should be satisfied after confirming the minimum operating voltage of the load. Supply voltage Internal voltage > drop of switch Minimum operating voltage of load 2) If the internal resistance of a light emitting diode causes a problem, select a switch without an indicator light (model D-/H/0/0V). <Solid state switches> 3) Generally, the internal voltage drop will be greater with a 2 wire solid state auto switch than with a reed switch. Take the same precautions as in 1). lso, note that a VDC relay is not applicable. 6. Pay attention to leakage current. <Solid state switches> With a 2 wire solid state auto switch, current (leakage current) flows to the load to operate the internal circuit even when in the OFF state. Operating current of load (OFF condition) > eakage current If the criteria given in the above formula are not met, it will not reset correctly (stays ON). Use a 3 wire switch if this specification will not be satisfied. Moreover, leakage current flow to the load will be n times larger when n auto switches are connected in parallel. 7. Do not use a load that generates surge voltage. <Reed switches> If driving a load such as a relay that generates a surge voltage, use a contact protection box. <Solid state switches> lthough a zener diode for surge protection is connected at the output side of a solid state auto switch, damage may still occur if the surge is applied repeatedly. When a load such as a relay or solenoid which generates surge is directly driven, use a type of switch with a built-in surge absorbing element.. Cautions for use in an interlock circuit When an auto switch is used for an interlock signal requiring high reliability, devise a double interlock system to avoid trouble by providing a mechanical protection function, or by also using another switch (sensor) together with the auto switch. lso perform periodic maintenance and confirm proper operation.. Ensure sufficient clearance for maintenance activities. When designing an application, be sure to allow sufficient clearance for maintenance and inspections. oad 26
uto Switch Precautions 2 e sure to read before handling. Mounting and djustment 1. Do not drop or bump. Do not drop, bump or apply excessive impacts (300m/s² or more for reed switches and 0m/s² or more for solid state switches) while handling. lthough the body of the switch may not be damaged, the inside of the switch could be damaged and cause a malfunction. 2. Do not carry a cylinder by the auto switch lead wires. Never carry a cylinder by its lead wires. This may not only cause broken lead wires, but it may cause internal elements of the switch to be damaged by the stress. 3. Mount switches using the proper tightening torque. If a switch is tightened beyond the of tightening torque, the mounting screws, mounting brackets or switch may be damaged. On the other hand, tightening below the of tightening torque may allow the switch to slip out of position. (Refer to page 1 for switch mounting instructions and tightening torque.) 4. Mount a switch at the center of the operating. djust the mounting position of an auto switch so that the piston stops at the center of the operating (the in which a switch is ON). (The mounting position shown in the catalog indicates the optimum position at stroke end.) If mounted at the end of the operating (around the borderline of ON and OFF), operation may be unstable. Wiring 1. void repeatedly bending or stretching lead wires. roken lead wires can result from wiring patterns which repeatedly apply bending stress or stretching force to the lead wires. 2. e sure to connect the load before power is applied. <2 wire type> If the power is turned ON when an auto switch is not connected to a load, the switch will be instantly damaged because of excess current. 3. Confirm proper insulation of wiring. e certain that there is no faulty wiring insulation (contact with other circuits, ground fault, improper insulation between terminals, etc.). Damage may occur due to excess current flow into a switch. 4. Do not wire with power lines or high voltage lines. Wire separately from power lines or high voltage lines, avoiding parallel wiring or wiring in the same conduit with these lines. Control circuits containing auto switches may malfunction due to Wiring noise from these other lines.. Do not allow short circuit of loads. <Reed switches> If the power is turned ON with a load in a short circuited condition, the switch will be instantly damaged because of excess current flow into the switch. <Solid state switches> D-M(V), D-MW(V), and all models of PNP output type switches do not have built-in short circuit protection circuits. Note that if a load is short circuited, the switch will be instantly damaged as in the case of reed switches. Take special care to avoid reverse wiring of the brown [red] power supply line and the black [white] output line on 3 wire type switches. 6. void incorrect wiring. <Reed switches> 24VDC switch with indicator light has polarity. The brown [red] lead wire is (+), and the blue [black] lead wire is ( ). 1) If connections are reversed, a switch will operate, however, the light emitting diode will not light up. lso note that a current greater than that specified will damage a light emitting diode and it will no longer operate. pplicable models: D-73/73H/73C D-3/3V 2) Note however, that in the case of 2 color indication auto switches (D-7W), the switch will be in a normally ON condition if the wiring is reversed. <Solid state switches> 1) If connections are reversed on a 2 wire type switch, the switch will not be damaged if protected by a protection circuit, but the switch will be in a normally ON state. However, it is still necessary to avoid reversed connections, since the switch could be damaged by a load short circuit in this condition. 2)If connections are reversed (power supply line + and power supply line ) on a 3 wire type switch, the switch will be protected by a protection circuit. However, if the power supply line (+) is connected to the blue [black] wire and the power supply line ( ) is connected to the black [white] wire, the switch will be damaged. ead wire colour changes ead wire colours of SMC switches have been changed in order to meet NEC Standard 02 for production beginning September, 16 and thereafter.

uto Switch Precautions 3 e sure to read before handling. Operating Environment 1. Never use in an atmosphere of explosive gases. The construction of auto switches is not intended to prevent explosion. Never use in an atmosphere with an explosive gas since this may cause a serious explosion. 2. Do not use in an area where a magnetic field is generated. uto switches can malfunction or magnets inside cylinders can become demagnetized. (Consult SMC regarding the availability of a magnetic field resistant auto switch.) 3. Do not use in an environment where the auto switch will be continually exposed to water. lthough switches satisfy IEC standard IP67 construction (JIS C 0: watertight construction), avoid using switches in applications where continually exposed to water splash or spray. Poor insulation or swelling of the potting resin inside switches may cause malfunction. 4. Do not use in an environment with oil or chemicals. Consult SMC if auto switches will be used in an environment with coolant, cleaning solvent, various oils or chemicals. If auto switches are used under these conditions for even a short time, they may be adversely affected by improper insulation, malfunction due to swelling of the potting resin, or hardening of the lead wires.. Do not use in an environment with temperature cycles. Consult SMC if switches are used where there are temperature cycles other than normal air temperature changes, as there may be adverse effects inside the switches. 6. Do not use in an environment where there is excessive impact shock. <Reed switches> When excessive impact (300m/s² or more) is applied to a reed switch during operation, the contact point will malfunction and generate or cut off a signal momentarily (1ms or less). Consult SMC regarding the need to use a solid state switch depending upon the environment. 7. Do not use in an area where surges are generated. <Solid state switches> When there are units (solenoid type lifter, high frequency induction furnace, motor, etc.) which generate a large amount of surge in the area around cylinders with solid state auto switches, this may cause deterioration or damage to the switches. void sources of surge generation and crossed lines.. void accumulation of iron waste or close contact with magnetic substances. When a large amount of iron waste such as machining chips or spatter is accumulated, or a magnetic substance (something attracted by a magnet) is brought into close proximity with an auto switch cylinder, it may cause auto switches to malfunction due to a loss of the magnetic force inside the cylinder. Maintenance 1. Perform the following maintenance periodically in order to prevent possible danger due to unexpected auto switch malfunction. 1) Securely tighten switch mounting screws. If screws become loose or the mounting position is dislocated, retighten them after readjusting the mounting position. 2) Confirm that there is no damage to lead wires. To prevent faulty insulation, replace switches or repair lead wires, etc., if damage is discovered. 3) Confirm the lighting of the green light on the 2 colour indicator type switch. Confirm that the green ED is on when stopped at the established position. If the red ED is on, the mounting position is not appropriate. Readjust the mounting position until the green ED lights up. Other 1. Consult SMC concerning water resistance, elasticity of lead wires, and usage at welding sites, etc. 2
Specific Product Precautions 1 e sure to read before handling. Refer to pages 23 through 2 for safety instructions, actuator precautions and auto switch precautions. llowable kinetic energy Selection 1. Do not use for intermediate cylinder stops. This cylinder is designed for locking against inadvertent movement from a stationary condition. Do not perform intermediate stops while the cylinder is operating, as this will shorten its service life. 2. Select the correct locking direction, as this cylinder does not generate holding force opposite to the locking direction. The extension lock does not generate holding force in the cylinder's retracting direction, and the retraction lock does not generate holding force in the cylinder's extending direction (free). 3. Even when locked, there may be stroke movement of about 1mm in the locking direction due to external forces such as the weight of the work piece. Even when locked, if air pressure drops, stroke movement of about 1mm may be generated in the locking direction of the lock mechanism due to external forces such as the work piece weight. 4. When locked, do not apply impact loads, strong vibration or rotational force, etc. This will lead to lock mechanism damage and reduced service life, etc..

Do not use 3 position valves. The lock may be released due to inflow of the unlocking pressure. 2. Install speed controllers for meter-out control. Malfunction may occur if meter-in control is used. 3. e careful of reverse exhaust pressure flow from a common exhaust type valve manifold. Since the lock may be released due to reverse exhaust pressure flow, use an individual exhaust type manifold or single type valve. 4. ranch off the compressed air piping for the lock unit between the cylinder and the speed controller. Use of an external branch may cause a reduction in service life.. Perform piping so that the side going from the piping junction to the lock unit is short.

Specific Product Precautions 2 e sure to read before handling. Refer to pages 23 through 2 for safety instructions, actuator precautions and auto switch precautions. Caution ø to ø only Mounting 1. e sure to connect the load to the rod end with the cylinder in an unlocked condition. If this is done when in a locked condition, it may cause damage to the lock mechanism. Preparing for Operation 1. When starting operation from the locked position, be sure to restore air pressure to the line in the pneumatic circuit. It is very dangerous to apply pressure to the line with the line in an unpressurized state, because the cylinder will move suddenly when unlocked. 2. Sizes ø to ø are shipped in the unlocked condition maintained by the unlocking bolt. e sure to remove the unlocking bolt following the procedures below before operation. The locking mechanism will not be effective without the removal of the unlocking bolt. 1) Confirm that there is no air pressure inside the cylinder, and remove dust cover. 2) Supply air pressure of 0.2MPa or more to unlocking port shown in the drawing on the left. 3) Use a hexagon wrench (width across flats: 2.) to remove unlocking bolt. Manual Unlocking 1. Do not perform unlocking when an external force such as a load or spring force is being applied. This is very dangerous because the cylinder will move suddenly. Take the following steps. 1) the lock after restoring the air pressure in the line of the pneumatic circuit to operating pressure, and then reduce the pressure gradually. 2) In case air pressure cannot be used, release the lock after preventing cylinder movement with a lifting device such as a jack. 2. fter confirming safety, operate the manual release following the steps shown below.

Specific Product Precautions 3 e sure to read before handling. Refer to pages 23 through 2 for safety instructions, actuator precautions and auto switch precautions. Caution Maintenance 1. In order to maintain good performance, operate with clean unlubricated air. If lubricated air, compressor oil or drainage, etc., enter the cylinder, there is a danger of sharply reducing the locking performance. 2. Do not apply grease to the piston rod. There is a danger of sharply reducing the locking performance. 3. Never disassemble the lock unit. It contains a heavy duty spring which is dangerous. There is also a danger of reducing the locking performance. 4. Never remove the pivot seal and disassemble the internal unit. Sizes ø to ø have a silver seal (pivot seal) of ø applied on one side of the lock body (opposite side from the unlocking port). The seal is applied for dust prevention, but there is no functional problem even if the seal is removed. However, never disassemble the internal unit. Holding the Unlocked Condition 1. Sizes ø to ø can hold the unlocked condition. <Holding the unlocked condition> 1) Remove the dust cover. 2) Supply air pressure of 0.2MPa or more to the unlocking port, and set the lock ring to the perpendicular position. 3) Screw the unlocking bolt which is included (hexagon socket head cap screw/ø, ø: M3 x l, ø: M3 x l) into the lock ring to hold the unlocked condition. Unlocking bolt Unlocking port Dust cover 2. To use the locking mechanism again, be sure to remove the unlocking bolt. The locking mechanism will not function with the unlocking bolt screwed-in.
