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
T erminal Protective Cover
When mounting the T erminal 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 af fect 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
T wo, 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.

Correct Tightening Torque
A loose screw may cause malfunctions. Be sure to tighten each
screw
to the proper tightening torque as shown in the table.
No. Type Torque
1 T erminal screw 0.78 to 1.18 N S m
2 Panel mounting screw 2.94 to 4.92 N S m
3 Side mounting screw 1.18 to 1.47 N S m
