Lever
The lever forged of anti-corrosive aluminium
alloy features high corrosion resistances
and outstanding ruggedness.
Shaft Section Seal
By fitting an O-ring to the rotary shaft and with
an appropriate interference of the screws,
high-sealing properties are maintained. The
O-ring is made of silicone rubber and is resistant to temperature changes and adverse
weather conditions.

Precautions
■ Correct Use
Handling
Operation
The bottom of the Switch at the cable outlet is resin-molded. Secure
the cable at a point 5 cm from the Switch bottom to prevent exertion
of excess force on the cable.
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 6.3S min. and hardness must
be Hv400 to 500.
When bending the cable, provide a bending radius of 45 mm min. so
as not to damage the cable insulation or sheath. Excessive bending
may cause fire or leakage current.
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.
Dog

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.

Connections
Be sure to connect a fuse with a breaking current 1.5 to 2 times
larger than the rated current to the Limit Switch in series in order to
protect the Limit Switch from damage due to short-circuiting.
When using the Limit Switch for the EN ratings, use the gI or gG 10A fuse.

Mounting
Do not expose the Switch to water exceeding 70°C or use it in steam.
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.

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
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
Note: 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.

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.
