Operation
• Operation method, shapes of cam and dog, operating frequency,
and overtravel have a significant effect on the service life and
precision of a Limit Switch. For this reason, the dog angle must be
30° max., the surface roughness of the dog must be 6.3 S min. and
hardness must be Hv 400 to 500.
• To allow the plunger-type actuator to travel properly, adjust the dog
and cam to the proper setting positions. The proper position is
where the plunger groove fits the bushing top.

• To allow the roller lever-type actuator to travel properly, adjust the
dog and cam so that the arrow head is positioned between the two
convex markers as shown below.

Mounting
• A maximum of 6 Switches may be group-mounted. In this case, pay
attention to the mounting direction so that the convex part of the
group-mounting guide on one Switch fits into the concave part of
the guide on the other Switch as shown in the figure below. For
group mounting, the mounting panel must have a thickness (t) of 6
mm min.

• If the mounting panel is warped or has protruding parts, a
malfunction may result. Make sure that the mounting panel is not
warped and has even surfaces.

• Use a Switch with a rubber cap when using the plunger type in an
environment where malfunction is possible due to environmental
conditions such as dust or cutting chips which may not allow
resetting.
• Do not expose the Switch to water exceeding 70°C or use it in
steam.
• When the D4C is used in a circuit of a device to be exported to
Europe, classified as Overvoltage Class III as specified in IEC664,
provide a contact protection circuit.
• Tighten each screw to a torque according to the following table.
No.
Type
Appropriate tightening torque*
1
M5 Allen-head bolt
4.90 to 5.88 N·m
2
M3.5 head mounting screw
0.78 to 0.88 N·m
3
M5 Allen-head bolt
4.90 to 5.88 N·m
* By removing the two screws from
the head, the head direction can
be rotated 180°. After changing the
head direction, re-tighten to the
torque specified above. Be careful
not to allow any foreign substance
to enter the Switch.
