The Omron D4C-1632 uses a sealed roller plunger actuator with a 12 mm diameter, 4.4 mm wide sintered stainless steel roller. Its linear plunger operation is designed for contact-actuated position detection in industrial machinery.
The single SPDT changeover contact supports a 5 A resistive load at 250 VAC and a 4 A resistive load at 30 VDC. Ratings for motor, inductive and lamp loads differ and must be considered during circuit design.
The D4C-1632 is equipped with a 3 m SJT(O) cable containing four conductors, including a protective earth connection. The cable is specified with UL and CSA approvals.
The sealed switch housing has an IP67 protection rating for suitable industrial environments. Installation practices and cable termination protection must follow the manufacturer's instructions.
The actuator has a maximum operating force of 17.65 N, a maximum pre-travel of 1.8 mm and a minimum over-travel of 3 mm. These mechanical limits support correct adjustment of the machine's actuation point.
OMRON specifies a mechanical durability of at least 10 million operations and an electrical durability of at least 200,000 operations under its reference load conditions. Actual service life varies with application conditions.

What is the Omron D4C-1632?
It is a compact enclosed mechanical limit switch featuring a sealed roller plunger, one SPDT changeover contact, a 3 m SJT(O) cable and an IP67 protection rating.
What actuator does the D4C-1632 use?
It uses a sealed roller plunger with a 12 mm diameter and 4.4 mm wide sintered stainless steel roller. It is not a roller lever switch.
What are its electrical contact ratings?
The switch is rated for 5 A at 250 VAC and 4 A at 30 VDC with resistive loads. Lower ratings apply to certain inductive, lamp and motor loads.
Does the switch provide normally open and normally closed contacts?
Yes. It has one SPDT changeover contact with common, normally open and normally closed switching paths.
Does it require a separate power supply?
The switch is a mechanically operated contact device and does not require an electronic supply to detect movement. It must be wired into a compatible control circuit within its contact ratings.
How long is the factory cable?
The cable is 3 m long and uses the SJT(O) specification with four conductors, including protective earth.
Is the D4C-1632 rated IP67?
Yes. OMRON specifies IP67 enclosure protection. This does not guarantee suitability for continuous immersion or every chemical environment.
What force is required to operate the plunger?
The maximum specified operating force is 17.65 N, and the minimum release force is 4.41 N.
What is the permitted plunger travel?
The maximum pre-travel is 1.8 mm, the maximum movement differential is 0.2 mm and the minimum over-travel is 3 mm. The operating position is 34.3 ±1 mm.
What is the maximum operating speed?
The permissible operating speed ranges from 0.1 mm/s to 0.5 m/s. The maximum switching frequencies are 120 mechanical or 30 electrical operations per minute.
What is the difference between D4C-1632 and D4C-1620?
Both models have standard-load contacts and 3 m SJT(O) cables. D4C-1632 uses a sealed roller plunger with linear travel, while D4C-1620 uses a roller lever actuator designed for rotary or angular actuation.
