Note: Appropriate terminal screw tightening torque: 0.78 to 1.18 N·m.
■ Mounting Holes
All switches can be mounted using M4 mounting screws with plane
washers or spring washers to securely mount the Switch. Tighten the
screws to a torque of 1.18 to 1.47 N·m.
Versions with panel mount plungers can be panel mounted via the
plunger, provided that the hexagonal nut of the actuator is tightened
to a torque of 2.94 to 4.9 N·m.
