• Approved by EN, UL, CSA, and CCC (Chinese standard).
(Ask your OMRON representative for information on
approved models.)
• Sealing characteristics that meet IEC IP67 degree of
protection.
• Triple-sealed construction:
Plunger section sealed via nitrile rubber packing seal and
diaphragm; switch section sealed via nitrile rubber cap;
cable entrance sealed via encapsulating material.
• Cable lengths of 3 and 5 m available on standard models.
Models also available with UL and CSA-certified cables.
• Multiple mounting possible with Switches with Plungers.
• Models with red LED indicators added to series for easy
confirmation of operation.
(Set by default to light for non-operation.)
• VCTF oil-resistant cables with CE marking.
(Applicable only to standard models.)
For the most recent information on models that have been certified for
safety standards, refer to your OMRON website.
Be sure to read Safety Precautions on page 13 to 14 and
Safety Precautions for All Limit Switches.

Note: Silicon rubber is used to increase resistance to the environment. Silicon rubber, however, can generate silicon gas. (This can occur at room temperature, but the
amount of silicon gas generated increases at higher temperatures.) Silicon gas will react as a result of arc energy and form silicon oxide (SiO2). If silicon oxide
accumulates on the contacts, contact interference can occur and can interfere with the device. Before using a Switch, test it under actual application conditions
(including the environment and operating frequency) to confirm that no problems will occur in actual.

Roller
The roller is made of self-lubricating sintered
stainless steel and boasts high resistance to
wear.
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.
Head-mounting
Screw
Diaphragm
The diaphragm is made of silicone rubber
and is resistant to temperature changes
and adverse weather conditions.
Cable
Vinyl cabtire cable and is resistant
to adverse weather conditions.
Lever
The lever forged of anti-corrosive aluminium
alloy features high corrosion resistances
and outstanding ruggedness.
Roller Lever Setscrew
This screw is made of stainless steel and has high
corrosion resistance.
Rotary Shaft
The shaft is made of stainless steel
decreasing the likelihood of rusting.
Built-in Switch
Both standard load and microload models available.

Safety Precautions
Refer to Safety Precautions for All Limit Switches.
Precautions for Correct Use
Handling
Operating Environment
• Seal material may deteriorate if a Switch is used outdoor or where
subject to special cutting oils, solvents, or chemicals. Always
appraise performance under actual application conditions and set
suitable maintenance and replacement periods.
• Install Switches where they will not be directly subject to cutting
chips, dust, or dirt. The Actuator and Switch must also be protected
from the accumulation of cutting chips or sludge.
Not Suitable
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.
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.
Suitable
• Constantly subjecting a Switch to vibration or shock can result in
wear, which can lead to contact interference with contacts,
operation failure, reduced durability, and other problems.
Excessive vibration or shock can lead to false contact operation or
damage. Install Switches in locations not subject to shock and
vibration and in orientations that will not produce resonance.
• The Switches have physical contacts. Using them in environments
containing silicon gas will result in the formation of silicon oxide
(SiO2) due to arc energy. If silicon oxide accumulates on the
contacts, contact interference can occur. If silicon oil, silicon filling
agents, silicon cables, or other silicon products are present near the
Switch, suppress arcing with contact protective circuits (surge
killers) or remove the source of silicon gas.
Bending radius
(R45 mm min.)
Secure
here
5 cm
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.

D4C
Operation
Mounting
• 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.
• 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.

• To allow the roller lever-type actuator to travel properly, adjust the

convex markers as shown below.

Indicator
• Indicator-equipped switch has contacts and indicator in parallel.
When contacts are open, leakage current flows through the
indicator circuit and may cause load's malfunction.
Please check the load's OFF current before use the indicatorequipped switch.
Two, 5.2-dia. or M5 screw holes
25±0.1
• 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.
