Precautions
Correct Use
Operating Method
Excessive dog angle, operating speed, or overtravel (OT) may
damage the actuator. Check that OT has a sufficient margin. The
actual OT should be rated OT x 0.7 to 1.
Handling
•
Do not expose the Switch to water exceeding 60
°
C or use it in
steam.
•
Do not use the Switch in oil or water.
•
An 8.5- to 10.5-dia. cable can be applied as seal rubber for the
lead wire outlet. (Use two- or three-core cable of VCT1.25 mm
2
.)
•
When detaching the Terminal Protective Cover, insert a
screwdriver and apply a force in the opening direction. Do not
use excess force to remove the cover. Doing so may cause
deformation in the fitting section and reduce the holding force.
Screwdriver
Terminal Protective Cover
When mounting the Terminal Protective Cover to the case, align the
cover on the case and then press the cover down to mount it firmly. If
the cover is pressed down in an inclined position, rubber packing will
deform and thus affect the sealing capability.

Mounting
When mounting the Switch with screws on a side surface, fasten the
Switch with M4 screws and use washers, spring washers, etc., to
ensure secure mounting.
Mounting Holes
Two, 4.3-dia. or M4 screw holes
•
When mounting the Panel Mount-type Switch (DCMC-5000,
D4MC5020, or D4MC5040) with screws on a side surface,
remove the hexagonal nuts from the actuator.
•
When mounting the panel mount type on a panel, be careful not
to tighten to an excessive torque. Tightening the screws to a
torque exceeding 4.91 N
S
m will cause the plunger to fail.
