Standard Switches with Operation Indicator
Note: Ask your nearest OMRON representative for information on Switching with approved international standards.
* Oil-resistant vinyl cabtire cables; approved by EN and IEC.
Pre-wired Models (Use VCTF Oil-resistant Cable)
Note: 1. The @ contains the length of the cable.
For example: 30 cm → D4C-2002-AK1EJ03
2. M1J models are also available. Contact your OMRON sales representative for further information.
3. Of the above model numbers, some with special specifications are not registered.
Weather-resistant Models
* Vinyl cabtire cable with excellent oil resistance.
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.

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.
Roller
The roller is made of self-lubricating sintered
stainless steel and boasts high resistance to
wear.
Head-mounting

Diaphragm
The diaphragm is made of silicone rubber
and is resistant to temperature changes

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.
Built-in Switch
Both standard load and microload models available.
Rotary Shaft
The shaft is made of stainless steel
decreasing the likelihood of rusting.

Note: 1. “Lit when not Actuated” means that when the actuator is in the free
position, the indicator is lit, and when the actuator is turned or pushed and
the contact comes into contact with the NO side, the indicator turns OFF.
2. Leakage current from indicator circuit may cause load's malfunction.
Please check the load's OFF current before use the indicator-equipped

Safety Precautions
Refer to Safety Precautions for All Limit Switches.
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.
•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.
Handling
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.
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 10-
A fuse.

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.
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 indicator-
equipped switch.
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.
