(Series MGZ) Slide key x 2 Tube rod diameter External dimension Series MGZ employs a slide bearing and a large bore tube rod that accounts for approximately % of the cylinder's external diameter. In addition, a built-in non-rotation mechanism using slide keys allows loads to be mounted directly. Improved work piece mounting accuracy Positioning holes on the work piece mounting surface allow easy alignment. Regulator with check valve is not required. A regulator with check valve, normally required for a lifting circuit, is no longer necessary. Excellent strength delivered in a small package. Although moment resistance is equivalent to that of a guided cylinder (cylinder + 2 guide shafts), the installation area has been reduced by approximately % (for Series MGZ). Features 1

Series MGZ/MGZR 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", "Warning" or "Danger". To ensure safety, be sure to observe ISO 44 Note 1), JIS 837 Note 2) and other safety practices. Caution : Operator error could result in injury or equipment damage. Warning : 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 837: General Rules for Pneumatic Equipment Warning 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 handled incorrectly. Assembly, 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. An application which has the possibility of having negative effects on people, property, or animals, requiring special safety analysis. 2
Series MGZ/MGZR Actuator Precautions 1 e sure to read before handling. Warning 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, bodily injury may occur, e.g., by having hands or get in the machinery, or damage to the machinery itself may occur. Therefore, the machine should be designed to prevent such dangers. 2. A protective cover is recommended to minimize the risk personal injury. If a driven object and moving parts of a cylinder pose a danger of personal injury, design the structure to avoid contact with the human body. 3. Securely tighten all staitionary parts and connected parts so that they will not become loose. Particularly when a cylinder operates with high frequency or is installed where there is a lot of vibration, ensure that all parts remain secure. 4. A deceleration circuit or shock absorber 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 cases such as these, the rigidity of the machinery should also be examined.. Consider a possible drop in operating pressure due to a power outage, etc. When a cylinder is used as part of 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 human injury or damage to machinery. Suspension mechanisms and lifting devices also require for drop prevention measures. 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 pneumatics, electricity or hydraulics, etc. 7. Design circuitry to prevent sudden lurching of driven objects. Take special care 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 particularly to limbs, and/or damage to equipment when this occurs. 8. Consider emergency stops. Design the system so that human injury and/or damage to machinery and equipment will not be caused when machinery is stopped by a safety device responding to abnormal conditions such as 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. Warning Selection 1. Confirm the specifications. The products featured in this catalog are designed for use in industrial compressed air systems. If the products are used in conditions where pressure and/or temperature are out of the range of specifications, damage and/or malfunction may occur. Do not use in these conditions. (Refer to specifications.) Consult SMC if fluid other than compressed air is required. 2. Intermediate stops When intermediate stopping of a cylinder piston is performed with a 3-position closed center type directional control valve, it is difficult to achieve stopping positions as accurate and precise as with hydraulic pressure due to the compressibility of air. Furthermore, since valves and cylinders are not guaranteed for zero air leakage, it may not be possible to hold a stopped position for an extended period of time. Contact SMC in case it is necessary to hold a stopped position for an extended period. 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 procedure for the maximum useable stroke. 2. Operate the piston in such a way that collision damage will not occur at the stroke end. Operate within such a range such that will prevent damage from occuring when a piston, having inertial force, stops by striking the cover at the stroke end. Refer to the cylinder model selection procedure for the maximum usable stroke. 3. Use a speed controller to adjust the cylinder drive speed, gradually increasing from a low speed to the desired speed setting. 4. Provide intermediate supports for long stroke cylinders. Provide intermediate supports for cylinders with long strokes to prevent rod damage due to sagging of the rod, deflection of the tube, vibration and external loads. 26
Series MGZ/MGZR Actuator Precautions 2 e sure to read before handling. Caution Expose approx. 2 threads Mounting 1. e certain to align the rod axis with the load and direction of movement when connecting. When a cylinder is not properly aligned, the rod and tube may be twisted. This can cause wear on areas such as the inner tube surface, bushings, rod surface, and seals cause damage on these areas. 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 by striking or grasping them with other objects. Cylinder bores are manufactured to precise tolerances, so that even a slight deformation may cause faulty operation. Also, scratches or gouges in the piston rod may lead to damaged seals and cause air leakage. 4. Prevent the sticking (through friction) of rotating parts. Prevent the sticking of rotating parts (pin etc.) by applying sufficient lubrication.. Do not use until you can verify that equipment can operate properly. Following mounting repairs, or conversions, verify correct mounting by conducting suitable function and leakage tests after piping and power connections have been made. 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. Caution Piping 1. Preparation before piping efore piping is connected, it should be thoroughly flushed out with air or water to remove chips, cutting oil, and other debris from inside the pipe. 2. Wrapping of sealant 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. Also, when sealant tape is used, leave 1. to 2 thread ridges exposed at the end of the threads. Caution Wrapping direction Lubrication Pipe tape 1. Lubrication of non-lube type cylinder The cylinder is lubricated for life at the factory and can be used without any further lubrication. However, in the event that it is lubricated additionally, be sure to use class 1 turbine oil (with no additives) ISO VG. Stopping lubrication later may lead to malfunction the new lubricant will cancel out the original lubricant. Therefore, lubrication must be continued once it has been started. 27 Warning Air Supply 1. Use clean air. Do not use compressed air containing chemicals, synthetic oils containing organic solvents, salt or corrosive gases, as this can cause damage or malfunction. Caution 1. Install air filters. Install air filters at the inlet side of valves. The filtration degree should be µm or finer. 2. Install an after-cooler, air dryer or water separator, etc. Air that includes excessive drainage or condensate 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 range of fluid and ambient temperature. Take measures to prevent freezing when C or less, since moisture in circuits can freeze and cause damage to seals and lead to malfunction. Refer to SMC s est Pneumatics catalog vol.4 for further details on compressed air quality. Warning Operating Environment 1. Do not use in environments where there is a danger of corrosion. Refer to the construction drawings regarding cylinder materials. 2. In dusty conditions or where water or oil splashing is a regular occurrence, protect the rod by installing a rod cover. 3. When using auto switches, do not operate in an environment where there are strong magnetic fields. Warning Maintenance 1. Perform maintenance inspection according to the procedure indicated in the instruction manual. Improper handling and maintenance may cause malfunctioning and damage of machinery or equipment to occur. 2. Removal of components, 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. Filter drainage Drain out condensate from air filters regularly.
Series MGZ/MGZR Auto Switch Precautions 1 e sure to read before handling. Warning 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 range of specifications of current load, 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. (When the allowable separation is indicated for each cylinder series, use the specified value.) 3. Monitor 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: V(mm/s) = Auto switch operating range x Load operating time 4. Keep wiring as short as possible. <Reed switch> As 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.) 1) For an auto switch without a contact protection circuit, use a contact protection box when the wire length is m or longer. 2) Even when an auto switch has a built-in contact protection circuit, if the lead wire length is 3 m or more, the rush current cannot be adequately absorbed and the life of the switch may be shortened. Contact SMC in such a case, as it will be necessary to connect a contact protection box to extend the life of the switch. <Solid state switch> 3) Although wire length does not affect switch function, use wiring m or shorter.. Monitor the internal voltage drop of the switch. <Reed switch> 1) Switches with an indicator light (Except D-Z76) 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 Similarly, when operating below a specified voltage, it is possible that the load may be ineffective even though the auto switch function is normal. 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-Z). <Solid state switch> 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). Also, note that a VDC relay is not applicable. 6. Monitor leakage current. <Solid state switch> 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. Current to operate load (OFF condition) > Leakage current If the condition given in the above formula is not met, it will not reset correctly (stays ON). Use a 3-wire switch if this specification connot 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 switch> If driving a load that generates surge voltage, such as a relay, use a switch with a built-in contact protection circuit or a contact protection box. <Solid state switch> Although a zener diode for surge protection is connected at the output side of a solid state auto switch, damage may still occur if a surge is applied repeatedly. When directly driving a load which generates surge, such as a relay or solenoid valve, use a type of switch with a built-in surge absorbing element. 8. 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 safeguard against malfunctions by providing a mechanical protection function, or by also using another switch (sensor) together with the auto switch. Also perform periodic inspection and confirm proper operation.. Ensure sufficient clearance for maintenance activities. When designing an application, be sure to allow sufficient clearance for maintenance and inspections. Load 28
Series MGZ/MGZR Auto Switch Precautions 2 e sure to read before handling. Warning Mounting and Adjustment 1. Do not drop or bump. Do not drop, bump or apply excessive impacts (3m/s 2 or more for reed switches and m/s 2 or more for solid state switches) while handling. Although 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. When a switch is tightened beyond the range of tightening torque, the mounting screws, mounting bracket or switch may be damaged. On the other hand, tightening below torque range may allow the switch to slip out of position. (Refer to page 23 for switch mounting, movement and tightening torque.) 4. Mount a switch at the center of the operating range. Adjust the mounting position of an auto switch so that the piston stops at the center of the operating range (the range in which a switch is ON). (The mounting positions shown in the catalog indicate the optimum position at stroke end.) If mounted at the end of the operating range (around the borderline of ON and OFF), operation will be unstable. Warning Wiring 1. Avoid repeatedly bending or stretching lead wires. roken lead wires will result from repeatedly applying 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 (such as 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 in conjunction 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 noise from these other lines. Wiring. Do not allow short circuit of loads. <Reed switch> 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 switch> D-J1 and all models of PNP output type switches do not have built-in short circuit protection circuits. If loads are short circuited, the switches will be instantly damaged, as in the case of reed switches. Take special care to avoid reverse wiring with the brown [red] power supply line and the black [white] output line on 3-wire type switches. 6. Avoid incorrect wiring. <Reed switch> A 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, the switch will still operate, but the light emitting diode will not light up. Also note that a current greater than the maximum specified one will damage a light emitting diode and make it inoperable. Applicable models: D-Z73 2) Note, however, in case of 2-color display type auto switch (D- AW), if the wiring is reversed, the switch will remain in a normally on condition. <Solid state switch> 1) Even if connections are reversed on a 2-wire type switch, the switch will not be damaged because it is protected by a protection circuit, but it will remain in a normally ON state. ut reverse wiring in a load short circuit condition should be avoided to protect the switch from being damaged. 2) Even if (+) and ( ) power supply line connections are reversed 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. Lead wire color changes Lead wire colors of SMC switches have been changed in order to meet NECA Standard 2 for production beginning September, 16 and thereafter. Please refer to the tables provided. Special care should be taken regarding wire polarity during the time that the old colors still coexist with the new colors. 2-wire Output (+) Output () Power supply GND Output Diagnostic output Old Red lack Solid state with diagnostic output Old Red lack White Yellow New rown lue New rown lue lack Orange 3-wire Power supply GND Output Power supply GND Output Latch type diagnostic output Old Red lack White Solid state with latch type diagnostic output Old Red lack White Yellow New rown lue lack New rown lue lack Orange 2
