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 label of "Caution", "Warning" or "Danger". To ensure safety, be sure to observe ISO 4414 Note 1), JIS B 8370 Note 2) and other safety practices.
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. 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 component 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.Before machinery/equipment is re-started, take measures to prevent shooting/out of cylinder piston rod etc. (Bleed 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 conjuction with atomic energy, railway, air navigation, vehicles, medical
equipment, food and beverage, 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.
Note 1) ISO 4414 : Pneumatic fluid power -- Recommendations for the application of equipment to transmission and control systems.
Note 2) JIS B 8370 : Pneumatic system axiom.
Warning
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.

1.Air cylinder has a possibility of dangerous sudden action if sliding part of machine is twisted due to external force etc.In such a case, it may harm or injure human body; e.g. by catching hand or foot in the machine, or it may damage the machine itself. Therefore, machine should be designed to avoid such troubles.
2.A protective cover is recommended to minimize the risk of personal injury. If a stationary object and moving parts of cylinder are in close, proximity personal injury may occur. Design the construction to avoid contact with human body.
3.Be sure to tighten any loose fixed and/or connected parts.When cylinder operates with high frequency or cylinder is installed where there is a lot of vibration, ensure that all parts remain secure.
4.Deceleration circuit and shock absorber may be required.When driven object is operated at high speed or heavy load, cylinder's cushion will not be enough to absorb the shock. Install deceleration circuit to reduce the speed before cushioning or install external shock absorber to relieve the shock. In this case, examine rigidity of machine.
5.Consider the possibility that operating pressure will be dropped by power outage etc..In case cylinder is used for clamping mechanism, there is a possibility of work dropping off caused by decrease of clamping force; therefore, install safety equipment not to allow damage to machine nor to human body. Suspension mechanism and lifting machine should be designed with safety equipment.
6.Consider loss of power source.Measures should be taken to protect human body and/or machine against unexpected drop of work due to loss of air pressure, electricity and hydraulics.
7.Design circuit to prevent sudden extension (Start up).When an air cylinder is exhausted and one side of the piston is pressurized as a result of exhaust center type directional control valve and/or holding after residual pressure is exhausted, the piston will advance at high speed. In this case, design equipment to avoid rapid advancement because it may cause personal injury and/or damage to machine.
8.Consider emergency stop.When machine is stopped by safety device under abnormal condition by power outage or manual emergency stop, design to not allow personal injury and/or damage to machine and equipment.
9.Consider the action when operation is re-started after emergency stop and abnormal stop.Design the machine so as personal injury or machine damage will not occur upon restart of equipment. When cylinder has to be re-set at starting position, install manual safety equipment.
1.Check 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.
Consult SMC if you use fluid except compressed air.
2.Intermediate stopWhen intermediate stop of piston is controlled by a 3 position closed center directional control valve, precise and accurate stop as with a hydraulic cylinder is difficult due to the compressibility of air.
Since zero air leakage of valve and cylinder are not guaranteed, stopped position during long time periods may not be held. Consult SMC if holding stop position for a long while is needed.
1.Adjust cylinder operating speed with speed controller from low speed side gradually to desired operating speed.
Warning
Caution
Series MGT
1.Do not scratch or dent 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 faulty operation. Also, scratches or dents etc. in the piston rod may lead to damaged seals and cause air leakage.
2.Do not use until you can verify that equipment can operate appropriately.Verify the correct mounting by suitable mechanism investigation and leakage investigation after compressed air and/or power is connected after mounting, maintenance and conversion.
3.Do not make any alterations to this product.Alterations made to this product may lead to a loss of durability and damage to the product, which in turn can cause human injury and damage to other equipment and machinery.
4.Do not enlarge the fixed throttle in the piping port by reworking it etc.If the throttle bore is enlarged, the drive speed of the product will increase as will the shock force. This may lead to damage to the product, which in turn can cause human injury and damage to other equipment and machinery.

WarningSelection
Actuator Precautions 2Be sure to read before handling.
1. Use clean air.If compressed air includes synthetic chemical materials, including organic solvents, salinity, corrosive gas, etc., it can cause damage or malfunction.
Air Supply
1.Preparation before piping.Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove cutting dust, cutting oil and other debris from inside the pipe.
2.Wrapping of pipe tape.When screwing together pipes and fittings etc., be certain that cutting dust from the pipe threads and sealing material do not get inside the piping.
Further, when pipe tape is used, leave 1.5 to 2 thread ridges exposed at the end.
1. Install an air filter.Install the air filter at the upstream side of the valve.
Filtration degree should be 5µm or less.
2.Install an air dryer, after cooler, etc.Air that includes much condensate causes malfunction of valves and other pneumatic equipment. To prevent this, install an air dryer, after cooler, etc.
3.Use the product in the range of specifications with regard to fluid temperature and ambient temperature.Measure freezing prevention since moisture in circuits will be frozen under -5°C, and this may cause damage of seals and malfunction.
Refer to "Air Cleaning Equipment" catalog for compressed air quality.
Piping
1.Lubrication of non-lube type cylinder.The cylinder is prelubricated and can be used without any further lubrication.
However, in the event that it will be lubricated, use turbine oil class 1 (with no additives) ISO VG32.
Stopping lubrication later may lead to malfunction due to the loss of the original prelubrication; therefore, lubrication must be continued once it has been started.

1. Do not use in environments consisting of corrosive gases, salt water, water or vapor.Refer to construction figure for cylinder material on page 7.
2.When using in an atmosphere where water drops, oil, spatter, etc. (e.g., welding) exist, take suitable countermeasures to ensure protection.
3.When an auto switch is used, do not use in a strong magnetic field.
Operating Environment
Warning
1.Maintenance should be done according to the procedure shown in the operating manual.If handled improperly, malfunction and damage of machinery or equipment may occur.
2.Machine maintenance and supply/exhaust of compressed air.When machinery is serviced, first check measures to prevent release of workpiece and run-away of equipment etc., and then cut the supply pressure and power to exhaust all compressed air from the system.
When machinery is restarted, check that operation is normal with actuators in the proper positions.
Maintenance
1.DrainRemove condensate from air filter regularly.
Caution
Warning
1.Confirm specifications.Read 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 40mm.
3.Pay attention to length of time that switch is ON at an intermediate stroke position.Setting up an auto switch at an intermediate position of strokes and driving load at the time a piston is passing, although auto switch would operate, load will not operate satisfactorily as the length of operating time will be shortened if speed is too fast. Detectable maximum piston speed is:
4. Wiring should be kept as short as possible.< Reed switch >
When a length of the wire toward load gets longer, the initial current at switching on would be greater to shorten the product's life. (The switch will stay ON all the time.)
1) For an auto switch without a protection circuit of the contact point, use a contact point protection box for the wire length 5m or longer.
< Solid state switch >
2) Although wire length should not affect switch function, use a wire
100mm or shorter.
5.Take precautions for internal voltage drop of switch.< Reed switch >
1) Switches with an indicator light (Except "D-A96", "A96V", "Z76")
• If auto switches are connected in series as shown below, take precautions that there will be a great voltage drop because of internal resistance of light emitting diode. (Refer to internal voltage drop in auto switch specifications.)[Voltage drop will be as much as n times when n auto switches are connected.]Although an auto switch operates normally, load may not operate.
• Operating under specified voltage, although an auto switch operate normally, load may not operate. Confirm minimum operating voltage of load and the following formula will apply.
Designing / Selection
2) If internal resistance of light emitting diode causes a problem, select switches without an indicator light (Model "D-A90", "90V", "Z80").
< Solid state switch >
3) Generally, internal voltage drop will be greater with 2 wire solid state auto switch than with reed switch. Take the same precaution as 1).
Also, note that 12VDC relay is not applicable.
6.Pay attention to leakage current.< Solid state switch >
With 2 wire solid state auto switch, current (leakage current) flows to a load to operate internal circuit even on the OFF status.
If criteria given by above formula is not met, it will not reset correctly (stays on). Use 3 wire switch if this specification will not be satisfied.
Leakage current flow to load will be as much as n times when n auto switches are connected in parallel.
7.Do not use load that generates surge voltage.< Reed switch >
If driving a load such as relay that generates a surge voltage, use switch with a built-in protection circuit of contact point or use a contact point protection box.
< Solid state switch >
Although zener diode for protection from surge is connected at the output side of solid state auto switch, it may still cause damage if surge will be repeatedly applied. When a load like relay or solenoid which generates surge is directly driven, use a type of switch with built-in surge absorption element.
8.Note for using interlock circuitWhen auto switch is used for an interlock signal for high reliability, build a double interlock system to prepare against troubles that setup a mechanic protective function or use a switch (sensor) other than an auto switch. Perform periodic maintenance and confirm proper operation.
9.Keep working clearances around actuation enough for maintenance.When designing application, be sure to allow for sufficient clearances for maintenance and inspection requirements.

Auto Switch Precautions 1Be sure to read before handling.
1.Do not drop or bump.Do not drop, bump or apply excessive impacts (300m⁄s2 or more for reed switch and 1000m⁄s2 or more for solid state switch) while handling.
Although the body of the switch does not get damaged, inside of switch could get damaged and it may cause malfunction.
2.Do not carry a cylinder by the auto switch lead wire.Never carry a cylinder by its lead wire. This not only causes a broken lead wire, it causes internal elements of the switch to be damaged by the stress.
3.Mount a switch within the limits of its tightening torque.When a switch is tightened beyond its limits of tightening torque, the mounting screws, mounting bracket or switch may get damaged. On the other hand, tightened under the limits of tightening torque, it may cause displacement of mounting position of a switch. (Refer to Page 6 to 8 for how to mount, how to move or tightening torque etc.)
4.Set a switch at the center of operating range.Set a mounting position of an auto switch to adjust that a piston stops at the center of the operating range (the ranges that a switch is ON).
(The mounting position shown in a catalog indicates the most optimized position at stroke end.) Setting at the end of operating range (around the borderline of ON and OFF), the operation will be unstable.
5.Do not short circuit with loads.< Reed switch >
If power is ON at a status that loads are short circuit, the switch is instantly damaged because of an excess current flow into switch.
< Solid state switch >
A protection circuit against short-circuit is not built-in for the models of D-F9 (V), F9 W(V) and all models of PNP output type. If loads are short circuit, the switch is instantly damaged.
Take special care to avoid reverse wiring with a power supply
line (brown) and a output line (black) on 3 wire type.
6.Avoid wrong wiring.< Reed switch >
24V DC switch with indicator light has a polarity. A brown lead line is (+) and a blue lead line is (-).
1) If a connection is reversed, a switch will operate, however light emitting diode will not be lit.
Also note that a current flow more than specified will damage light emitting diode and will not operate.
Models applied: D-Z73, D-A93, A93V
< Solid state switch >
1) If connection is reverse on a 2 wire type switch, a switch will not be damaged if protected by a protection circuit, however switch will always stay in ON status. However it is still necessary to take care not to reverse connection since switch could be damaged by a load short circuit in this condition.
2) If connection is reversed (reversed power supply line + and power supply line -) on 3 wire type switch, a switch will be protected by protection circuit. However, with a connection power supply line (+) to blue line and power supply line (-) to black line, switch will be damaged.
Mounting and Adjustment
1.Avoid repeatedly bending or stretching lead wires.Broken lead wires will result from applying a force of bending stress or stretching to lead wire.
2.Make sure to connect the load before power is applied.<2 wire>
If power is ON at a time when an auto switch is not connected to a load, the switch is instantly damaged because of an excess current.
3.Confirm proper insulation against wiring.Ensure proper insulation (contact with other circuits, ground fault, improper insulation between terminals etc.) at wiring. It causes a damage as an excess current flow into a switch.
4.Do not wire with power lines or high voltage lines.Wire separately with power lines or high voltage lines, avoiding to wire with these lines in parallel or in a same wiring pipe.

Lead wire colors of SMC switches and related products have been changed in order to meet NECA (Nippon Electric Control Equipment Industries Association) Standard 0402 for production beginning September, 1996 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.
1.Never use in an atmosphere with explosive gas. Structure of auto switches is not intended to prevent explosion. Never use in an atmosphere with an explosive gas since it may cause explosive disaster.
2.Do not use in an area where magnetic field is generated.Auto switches will malfunction or magnets inside cylinders will become demagnetized. (Consult SMC for availability of an antimagnetic field auto switch.)
3.Do not use in an environment continually exposed to water.Although switches except few models meet IEC standard IP67 structure (JIS C 0920: anti-immersion structure), do not use switches in applications where continually exposed to water splash or spray. Poor insulation or swelling of potting resin inside switches may cause malfunction.
4.Do not use in an environment with oil or chemicals.Consult SMC when auto switches will be used under the environment with coolant, cleaning solvent, various oil or chemicals. Even for a short period of time that auto switches are used under these condition, they may be adversely affected by improper insulation, malfunction by swelling of potting resin or hardening lead wires.
5.Do not use in an environment of temperature cycle.Consult SMC if switches are used under temperature cycle other than normal temperature changes as they may be adversely affected.
6.Do not use in an environment that has excessive impact shock.
< Reed switch >
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 the signal for instantaneous (1ms or less). Consult SMC for necessity of using a solid state switch according to an environment.
7.Do not use in the area where surge is generated.
< Solid state switch >
When there are units (solenoid type lifter, high frequency induction furnace, motor etc.) in which great surge is generated around cylinders with a solid state auto switch, it may deteriorate or damage the switch. Avoid sources of generating surge and disorganized lines.
8.Avoid accumulation of iron powder or close contact of magnetic substance.When a large amount of ferrous powder like machining chips or spatter is accumulated or magnetic substance (something magnet attracts) is brought in close proximity to auto switch cylinder, it may cause auto switch to malfunction as magnetic force inside cylinder would be lost.
Environment
1.As auto switches may malfunction unexpectedly and would not be able to secure safety, perform following maintenance periodically.1) Secure and tighten switch mounting screws.
If screws were loosened or mounting position dislocated, tighten them after the mounting position is readjusted.
2) Confirm that there is not any damage to lead wires.
To prevent improper insulation, change switches or repair lead wires if damages are discovered.
3) Confirm lighting of green light on 2 color indicator light.
Confirm a green LED light is lit and stop at the adjusted position. If a red LED light is lit, mounting position is not appropriate. Readjust mounting position until green LED becomes lit.
Maintenance
1.Consult SMC concerning water proof efficiency, elasticity of lead wires, and usage at welding site.

Series MGT /Specific Product Precautions
1.Do not scratch or dent the sliding parts of the piston rod and guide rods.Damage to seals may cause air leaks or faulty operation.
2.In cases where the cylinder will be bottom mounted and shock will be delivered during use, the mounting bolts should be inserted to a depth of 2d or more.
3.If the cylinder is to be bottom mounted, by-pass ports should be provided for the guide rods.Since the guide rods protrude from the bottom of the cylinder at the end of the retracting stroke, in cases where the cylinder is to be bottom mounted it is necessary to provide by-pass ports for the guide rods in the mounting surface, as well as holes for the hexagon socket head screws which are used for mounting.
Mounting
Caution1.Do not put hands or fingers between the
plate and body. Care should be taken that hands or fingers do not get caught in the
space between the cylinder body and the plate when air pressure is applied.
2.When rotating the turntable, take care that hands or fingers are not caught by the position detector auto switch bracket.Because there is a danger of hands or fingers getting caught between the switch bracket and one of the magnet arms, please use caution when the turntable is being rotated.
