16 Series CXSJ Auto Switch Mounting Watchmaker s screwdriver Set screw Auto switch Use a watchmaker s screwdriver with a handle to mm in diameter when tightening the auto switch mounting screw. Tightening torque should be approximately 0.0 to 0. N m. Caution q Avoid proximity to magnetic objects. When magnetic substances such as iron (including flange brackets) are in close proximity to an auto switch cylinder (switch mounting side), be sure to provide a clearance between the magnetic substance and the cylinder body as shown in the drawing below. If the clearance is less than 0 mm, the auto switch may not function properly. w For CXSJ/0, the switch cannot be attached or detached from the plate side if the middle groove (indicated by arrows in the figure on the right) is used. (It will interfere with the bumper bolt at the end of the groove.) 0 mm 0 mm Other than the applicable auto switches listed in How to Order, the following auto switches can be mounted. Normally closed (N.C. = b contact), solid state switches (D-F9G and D-F9H type) are also available. For details, refer to Best Pneumatics 0 Vol. catalog.

Internal voltage drop in switch is V. 7 Switch Switch 2 Load When two switches are connected in series, a load may malfunction because the load voltage will decrease when in the ON state. The indicator lights will illuminate if both of the switches are in the ON state. 2-wire with 2-switch OR connection Switch Switch 2 Load (Solid state) When two switches are connected in parallel, a malfunction may occur because the load voltage will increase when in the OFF state. Load voltage at OFF = Leakage current x 2 pcs. x Load impedance = ma x 2 pcs. x 3 kω = V Example: Load impedance is 3 kω. Leakage current from switch is ma. (Reed) Because there is no current leakage, the load voltage will not increase when turned OFF. However, depending on the number of switches in the ON state, the indicator lights may sometimes dim or not light because of the dispersion and reduction of the current flowing to the switches.

25 Series CXSJ Auto Switches Precautions Be sure to read this before handling. Warning. 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. We do not guarantee any damage in any case the product is used outside of the specification range. 2. 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. However 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 (mm) Load operating time (ms) 3. Keep wiring as short as possible. <Reed switch> In the case of an auto switch with no contact protection circuit: 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.) Use a contact protection box when the wire length is m or longer. <Solid state switch> Although wire length should not affect switch function, use a wire 00 m or shorter. If the wiring is longer it will likely increase noise although the length is less than 00 m. When the wire length is long, we recommend attaching the ferrite core to the both ends of the cable to prevent excess noise.. Do not use a load that generates surge voltage. If a surge voltage is generated, the discharge occurs at the contact, possibly resulting in the shortening of product life. <Reed switch> If driving a load such as a relay that generates a surge voltage, use 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 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. Since the solid state auto switch is a semiconductor switch which has no contacts, no contact protection box is needed.. 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. Also perform periodic maintenance and confirm proper operation.. Do not make any modifications (including exchanging the printed circuit boards) to the product. It may cause human injuries and damage. Design and Selection x 000 Caution. Take precautions when multiple actuators are used close together. When two or more actuators are lined up in close proximity to each other, magnetic field interference may cause the switches to malfunction. Maintain a minimum cylinder separation of 0 mm. (When the allowable interval is specified for each cylinder series, use the indicated value.) The auto switches may malfunction due to the interference from the magnetic fields. 2. Take note of the internal voltage drop of the switch. <Reed switch> ) Switches with an indicator light (Except D-A9, A9V) 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. Load In the same way, when operating under 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- A90, A90V). <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 ). For details, refer to Example of AND (serial) and OR (parallel) connection on page 7. Also, note that a 2 VDC relay is not applicable. 3. Pay attention to 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. Operating current of > Leakage current load (OFF condition) 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. Refer to page 7. Back page 2

26 Series CXSJ Auto Switches Precautions 2 Be sure to read this before handling. Design and Selection Caution. Ensure sufficient clearance for maintenance activities. When designing an application, be sure to allow sufficient clearance for maintenance and inspections.. Use the cylinder and switch in proper combination. The auto switch is pre-adjusted to activate properly for an auto-switch-capable SMC cylinder. If the auto switch is mounted improperly, used for another brand of cylinder or used after the alternation of the machine installation, the switch may not activate properly. Mounting and Adjustment Warning. Instruction manual Install the products and operate them only after reading the instruction manual carefully and understanding its contents. Also keep the manual where it can be referred to as necessary. 2. Do not drop or bump. Do not drop, bump or apply excessive impacts (300 m s 2 or more for reed switches and 000 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. 3. Mount switches using the proper fastening torque. When a switch is tightened beyond the range of fastening torque, the mounting screws, mounting bracket or switch may be damaged. On the other hand, tightening below the range of fastening torque may allow the switch to slip out of position. (For mounting and moving auto switches, tightening torque, etc., refer to each series.). 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 position shown in a catalog indicates 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 or the service life will be shortened. <D-M9(V)> When the D-M9(V) auto switch is used to replace old series auto switch, it may not activate depending on operating condition because of its shorter operating range. Such as Application where the stop position of actuator may vary and exceed the operating range of the auto switch, for example, pushing, pressing, clamping operation, etc. Application where the auto switch is used for detecting an intermediate stop position of the actuator. (In this case the detecting time will be reduced.) In these applications, set the auto switch to the center of the required detecting range. Mounting and Adjustment Caution. Do not carry an actuator by the auto switch lead wires. Never carry a cylinder (actuator) 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. 2. Fix the switch with appropriate screw installed on the switch body. If using other screws, switch may be damaged. Wiring Warning. Confirm proper insulation of wiring. Be 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. 2. 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, including auto switches, may malfunction due to noise from these other lines. Caution. Avoid repeatedly bending or stretching lead wires. Repeated bending or tensile force applied to the lead wire may cause the sheath to fall off or disconnection of the wire. If bending or tensile force are not avoidable, fix the lead wire close to the switch and allow a bend radius of R0 to 0 mm or larger. Please consult SMC for details. Stress and tensile force applied to the connection between the cable and switch increases the possibility of the sheath to fall off or disconnection. Fix the cable in the middle so that it is not movable in the area where it connects with the switch. 2. Be 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. It is the same as when the 2-wire brown cord (+, output) is directly connected to the (+) power supply terminal. Back page 3

27 Series CXSJ Auto Switches Precautions 3 Be sure to read this before handling. Wiring Caution 3. 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> Model D-M9(V), F9BA and all models of PNP output type switches do not have built-in short circuit prevention 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 power supply line (brown) and the output line (black) on 3-wire type switches. The 2-wire type brown lead wire is for output, and the 3-wire type lead wire with the same brown color is the + power supply line. If the 2-wire type brown lead wire is connected to the location where the 3-wire type brown lead wire has been wired, a load short (no load) will result, causing overcurrent and damage to the switch.. Avoid incorrect wiring. <Reed switch> A 2 VDC switch with indicator light has polarity. The brown lead wire is (+) and the blue lead wire is ( ). ) If connections are reversed, a switch will operate, however, the light emitting diode will not light up. Also note that a current greater than that specified will damage a light emitting diode and it will no longer operate. Applicable models: D-A93, A93V <Solid state switch> ) 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 always stay in an 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 wire and the power supply line ( ) is connected to the black wire, the switch will be damaged. <D-M9(V)> The D-M9(V) does not have built-in short circuit protection circuit. Be aware that if the power supply connection is reversed (e.g. (+) power supply wire and ( ) power supply wire connection is reversed), the switch will be damaged.. When the cable sheath is stripped, confirm the stripping direction. The insulator may be split or damaged depending on the direction. (D-M9(V) only) Operating Environment Warning. 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. Auto switches will malfunction or magnets inside actuators will become demagnetized. 3. Do not use in an environment where the auto switch will be in water or continually exposed to water. Although switches satisfy IEC standard IP7 construction (JIS C 09: waterproof construction), do not use switches in applications where continually exposed to water splash or spray. Poor insulation or swelling of the potting resin inside switches may cause malfunction.. Do not use in an environment with oil or chemicals. Please 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. Please consult SMC if switches are used where there are temperature cycles other than normal temperature changes, as they may be adversely affected internally.. Do not use in an environment where there is excessive impact shock. <Reed switch> When excessive impact (300 m/s 2 or more) is applied to a reed switch during operation, the contact point will malfunction and generate or cut off a signal momentarily ( ms or less). Please 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 switch> When there are units (solenoid type lifter, high frequency induction furnace, motor, radio equipment etc.) which generate large surges or electromagnetic waves in the area around actuators with solid state auto switches, this may cause deterioration or damage to the switches. Avoid sources of surge generation and crossed lines. Recommended Tool Model name Wire stripper Model no. D-M9N-SWY Stripper for a round cable (ø2.0) can be used for a 2-wire type cable. Back page
