etc.

Caution

Caution indicates a hazard with a low level of risk which, if not avoided, could

result in minor or moderate injury.

Warning

Warning indicates a hazard with a medium level of risk which, if not avoided,

could result in death or serious injury.

result in death or serious injury.

Warning

1. The compatibility of the product is the responsibility of the person who designs the
equipment or decides its specifications.

Since the product specified here is used under various operating conditions, its compatibility with specific
equipment must be decided by the person who designs the equipment or decides its specifications
based on necessary analysis and test results.
The expected performance and safety assurance of the equipment will be the responsibility of the
person who has determined its compatibility with the product.
This person should also continuously review all specifications of the product referring to its latest catalog
information, with a view to giving due consideration to any possibility of equipment failure when
configuring the equipment.

2. Only personnel with appropriate training should operate machinery and equipment.

The product specified here may become unsafe if handled incorrectly.
The assembly, operation and maintenance of machines or equipment including our products must be
performed by an operator who is appropriately trained and experienced.

3. Do not service or attempt to remove product and machinery/equipment until safety is
confirmed.

1. The inspection and maintenance of machinery/equipment should only be performed after measures to

prevent falling or runaway of the driven objects have been confirmed.

2. When the product is to be removed, confirm that the safety measures as mentioned above are

implemented and the power from any appropriate source is cut, and read and understand the specific
product precautions of all relevant products carefully.

3. Before machinery/equipment is restarted, take measures to prevent unexpected operation and malfunction.

4. Contact SMC beforehand and take special consideration of safety measures if the
product is to be used in any of the following conditions.

1. Conditions and environments outside of the given specifications, or use outdoors or in a place

exposed to direct sunlight.

2. Installation on equipment in conjunction with atomic energy, railways, air navigation, space, shipping,

vehicles, military, medical treatment, combustion and recreation, or equipment in contact with food and
beverages, emergency stop circuits, clutch and brake circuits in press applications, safety equipment or
other applications unsuitable for the standard specifications described in the product catalog.

3. An application which could have negative effects on people, property, or animals requiring special

safety analysis.

4. Use in an interlock circuit, which requires the provision of double interlock for possible failure by using

a mechanical protective function, and periodical checks to confirm proper operation.

Caution

■Do not touch terminals and printed circuit board inside the product.

Otherwise it can cause electric shock, malfunction or damage to the product can result.

■After maintenance is complete, perform appropriate functional inspections.

Stop operation if the equipment does not function properly.

Safety cannot be assured in the case of unexpected malfunction.

■Be sure to confirm the wiring condition.

This series, including this product, is not equipped with excessive current protection.
Therefore, incorrect wiring and or a short-circuited load could damage and or burn this product.

■NOTE

○Follow the instructions given below when designing, selecting and handling your Auto switch.

The instructions on design and selection (installation, wiring, environment of use, adjustment, operation,

maintenance and etc.) described below must also be followed.

•Do not place two or more actuators close together.

When using more than two Auto switches mounted parallel with each other, keep 40 mm or more between actuator
tubes to prevent influence (malfunction) due to magnetic interference. (Keep the allowable displacement for each
Auto switch if specified)

•Detection of a piston by Auto switch mounted in the middle part of a cylinder stroke depends on the
speed of the piston. Satisfy the conditional equation below.

Where the maximum detectable piston speed = V (mm/s)

V (mm/s) =

Travel of auto switch (mm)

Change over time of load (ms)

•Reserve a space for maintenance.

Remember to leave space for maintenance when installing the product.

Product handling

Installation

•Follow the specified tightening torque. (0.05 to 0.15 Nm)

Excessive tightening torque can break the mounting screws, mounting bracket or Auto switch.
Insufficient tightening torque can displace the Auto switch from the original position.
(Refer to the installation manual)

•Connect frame-ground terminal (FG terminal) to the ground when using a switching power supply.

•Do not drop, hit or apply excessive shock (larger than 1000 m/s
