Dimensions
■ General-purpose and Split Contact Models
Note: Unless otherwise specified, all units are in millimeters and a tolerance of ± 0.4 mm applies to all dimensions
Terminals
Mounting
All switches can be side 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.
Note:
Mount using either the side mounting holes or the panel mount
plunger, not both. If using the side mounting holes, then remove
the hexagonal nut(s) from the panel mount plunger
.
