6.How to mount / Mounting bracket
Each actuator has a specified mounting bracket when mount-
ed to the autoswitch.
“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 a magnet built-in type, then ensure
brackets correspond to the actuator.
M2.5 mount screw tightening torque shall be 0.1 to 0.2N•m
•Setting the detecting position
Set the actuator at the stroke end. Set the switch in the area to where
the auto switch red lamp lights. (Detecting actuator end)
Based on A and B dimensions in the actuator catalogue, set the switch.
