Omron D4C-2320 Limit Switch
Omron D4C-2320 is a general-purpose limit switch with an R38 roller lever using a 17.5 mm × 7 mm sintered stainless steel roller for machine position and travel detection. The lever actuator suits moving parts that sweep across the sensing point, while the SPDT contact form provides changeover switching for general loads. The source specifies high inrush capability on the NC and NO contact paths, IP67 protection, and operation from -10 to 70°C. The D4C-2320 belongs to the D4C Series within the R38 roller lever limit switch range from Omron control products for machine travel, position, and end-point sensing where rolling lever actuation is preferred over direct plunger contact.

The Omron D4C-2320 Limit Switch uses an R38 roller lever with a 17.5 mm × 7 mm sintered stainless steel roller for machine position and travel detection. The lever actuator provides rolling contact with moving parts that sweep across the sensing point, while the SPDT contact form provides changeover switching for general loads. The source specifies 50/60 Hz operation and inrush current capability of 20 A maximum on the NC side and 10 A maximum on the NO side. IP67 protection covers the enclosed switch body, and the operating temperature range is -10 to 70°C.
The D4C-2320 supports 35 to 95% relative humidity and is listed for pollution degree 3 under EN60947-5-1. Destructive shock resistance reaches 1,000 m/s² maximum, while malfunction shock resistance reaches 500 m/s² maximum. Initial contact resistance is 400 mΩ maximum. The R38 roller lever is the principal actuator feature and is suited to targets that sweep across the switch rather than push directly into a plunger. The supplied row does not state a normal-load current rating or durability figures, so those values are not added here. For a related D4C R38 roller-lever model with a stated 5 A at 125 VAC rating, see the D4C-2220 model.
