Omron D4C-2232 Limit Switch
Omron D4C-2232 is a general-purpose limit switch with a 12 mm × 4.4 mm sintered stainless steel roller plunger for repeatable machine position detection. The rolling actuator suits cams, slides, and moving parts that pass across the sensing point, while the SPDT contact form provides changeover switching for general loads. This model is rated at 5 A at 125 VAC and supports high inrush current on the NC and NO paths. IP67 protection and operation from -10 to 70°C support enclosed installations. The D4C-2232 belongs to the D4C Series within the roller plunger limit switch range from Omron control products for machine position, travel, and end-point sensing with smooth roller contact.

The Omron D4C-2232 Limit Switch uses a 12 mm × 4.4 mm sintered stainless steel roller plunger for repeatable machine position detection. The rolling actuator suits cams, slides, and moving parts that pass across the sensing point, reducing sliding contact compared with a plain pin plunger. Its SPDT contact form provides changeover switching for general loads, and the model is rated at 5 A at 125 VAC at 50/60 Hz. Inrush current capability reaches 20 A maximum on the NC side and 10 A maximum on the NO side. IP67 protection covers the enclosed switch body.
The D4C-2232 operates from -10 to 70°C with 35 to 95% relative humidity and is listed for pollution degree 3 under EN60947-5-1. It is a Class I device with an earth wire. Destructive shock resistance reaches 1,000 m/s² maximum and malfunction shock resistance reaches 500 m/s² maximum. These characteristics suit roller-plunger position sensing where the target passes across the actuator and SPDT switching is required. The 12 mm × 4.4 mm roller dimensions are the main mechanical selection detail. For a related D4C model using a cross roller plunger with the same 5 A at 125 VAC rating, see the D4C-2203 model.
