NOTE
•
Follow the instructions given below when designing, selecting and handling the product.
■
The instructions on design and selection
(installation, wiring, environment, adjustment, operation,
maintenance, etc.)
described below must also be followed.
♦
Product specifications
•Use the specified voltage.
Otherwise failure or malfunction can result.
•Do not place two or more actuators close together.
When using two or more actuators closely in parallel, keep a distance of at least 40 mm between the actuator tubes
to prevent magnetic interference from affecting the product, which can cause malfunction.
(If the distance is specified for the actuator, use that value.)
•Detection by an Auto switch mounted in a mid-stroke position depends on the piston speed. Conditions
must satisfy the equation below.
Wherein;
Maximum detectable piston speed = V [mm/s]

•Design the product to prevent reverse current when the circuit is opened or the product is forced to
operate for operational check.
Reverse current can cause malfunction or damage to the product.
•Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.

Product handling
♦
Installation
•Tighten to the specified tightening torque. (0.05 to 0.15 Nm)
If the tightening torque is exceeded the mounting screws and brackets may be broken. If the tightening torque is
insufficient, the product can be displaced.
(Refer to "Mounting and Installation" on page 11.)
•Be sure to ground terminal FG when using a commercially available switch-mode power supply.
•Never mount an actuator equipped with Auto switch in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
•Do not drop, hit or apply excessive shock (over 1000 m/s
2
) to the Auto switch.
Otherwise damage to the internal parts can result, causing malfunction.
♦
Wiring
•Do not pull hard on the lead wire. In particular, never lift an Auto switch actuator by holding the lead
wires.
Otherwise damage to the internal parts can result, causing malfunction.
•Avoid repeatedly bending or stretching the lead wire, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause the sheath of the wire to peel off, or breakage of the wire.
If the lead wire can move, fix it near the body of the product.
The recommended bend radius is 40 to 80 mm. Contact SMC for details.
•Wire correctly.
Incorrect wiring can break the product.
•Do not perform wiring while the power is on.
Otherwise damage to the internal parts can result, causing malfunction.
•Do not route wires and cables together with power or high voltage cables.
Otherwise the product can malfunction due to interference of noise and surge voltage from power and high voltage
cables to the signal line. Route the wires (piping) of the product separately from power or high voltage cables.
•Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
