Frequently Asked Questions - D4C OMRON

What is the difference between standard D4C models and weather-resistant models?

Weather-resistant models (suffix -P) are designed for outdoor use with S-FLEX VCTF cable and UV-resistant silicone seals for extreme temperatures. They offer better sealing and corrosion resistance.

How to properly install the D4C sensor?

Fix the sensor using two M5 screws in the 5.1 mm holes. Tighten screws to a torque of 4.90 to 5.88 N·m. For the cable, allow a bending radius of at least 45 mm and secure it 5 cm from the housing to avoid strain.

What to do if the sensor does not switch correctly?

Check the alignment of the dog or cam: for a plunger, adjust the position so that the plunger groove aligns with the top of the sleeve. For a roller lever, ensure the arrow is between the two convex marks. Also check screw tightness and absence of foreign objects.

What does the model code D4C-□801 mean?

The code breaks down as: D4C- (series), □ (current: 1=5A/250VAC without LED, 2=5A/125VAC with LED, 3=4A/30VDC with LED, etc.), 8 (VCTF cable 2m), 01 (pin plunger actuator). Refer to the manual for full meaning.

Can the D4C be used with very low loads?

Yes, models D4C-4, D4C-5 and D4C-6 are designed for microloads (0.1 A). They have a minimum switching voltage of 5 VDC and minimum current of 0.16 mA. They are suitable for electronic circuits.

How to wire the D4C sensor electrically?

The standard cable has 4 conductors: black (COM), white (NO), red (NC), green/yellow (ground). For models with LED, wiring is similar. Use a 10 A type gG fuse for protection. Follow the wiring diagrams provided in the manual.

What periodic maintenance is recommended?

Clean the sensor regularly with a soft dry cloth. Check the tightness of mounting screws and the head. Inspect the cable for cuts or deformation. Replace worn parts (seals, rollers) if necessary.

Is the D4C compatible with ASI systems?

Yes, there are pre-wired models with M12 connector (M1J references) for ASI devices. These models have two conductors (NO) and are compatible with the ASI bus. Contact your OMRON representative for more details.

What is the typical lifespan of the sensor?

The mechanical life is at least 10 million operations, and the electrical life is at least 200,000 operations for a 5A/250VAC load. These values may vary depending on operating conditions (temperature, frequency, load type).

Where can I find spare parts for the D4C?

Spare parts (heads, actuators, mounting plates) are available under specific references (e.g., D4C-0001 for pin plunger head). Contact your OMRON distributor or consult the technical catalog to order.

■ Correct Use

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.

Secure here 5 cm

Bending radius: (R45 mm min.)

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 gl 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 6.3S min. and hardness must be Hv400 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.

Dog Bushing top Groove 2.8 mm

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.

Arrowhead Correct Not correct Convex markers Correct Not correct

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.

Group Mounting

Group Mounting Group-mounting guide (Front: convex Rear: concave)

16 mm Mounting panel Group-mounting guide (Front: convex Rear: concave)

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.

Mounting Holes

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.

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
