6.How to mount / Mounting bracket

Each actuator has a specified mounting bracket when mounted to the auto switch. “How to mount/Mount bracket” depends on actuator type and tube I.D. Please refer to the actuator catalogue. When an auto switch is mounted for the first time, please ensure the actuator is of the magnet built-in type, then prepare brackets that correspond to the actuator.

31.4

Slide the auto switch mounting nut inserted into the mounting rail and set it at the auto switch mounting position.

Fit the convex part of auto switch mounting arm into the concave part of auto switch mounting rail. Then slide the switch over the nut. (CDQ2 series:Fit the convex part of auto switch mounting arm through the auto switch spacer into the concave part of auto switch mounting rail.)

Push the auto switch mounting screw lightly into the mounting nut through the hole of auto switch mounting arm.

After reconfirming detection position, tighten the mounting screw to secure the auto switch. (Tightening torque of M3 screw should be 0.5 to 0.7N•m.)

Modification of the detecting position should be made in the condition
