Omron D4C-2203 Limit Switch
Omron D4C-2203 is a general-purpose limit switch with a 12 mm × 4.4 mm cross roller plunger using a sintered stainless steel roller for directional position detection. The cross-roller actuator suits 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-2203 belongs to the D4C Series within the cross roller plunger switch range from Omron control products for directional machine travel and position sensing.

The Omron D4C-2203 Limit Switch uses a 12 mm × 4.4 mm cross roller plunger with a sintered stainless steel roller for directional mechanical position detection. The cross-roller actuator suits targets that pass across the sensing point, while the SPDT contact form provides changeover switching for general loads. The model is rated at 5 A at 125 VAC and operates 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, and operation is specified from -10 to 70°C with 35 to 95% relative humidity.
The D4C-2203 is listed for pollution degree 3 under EN60947-5-1 and as Class I with an earth wire. Destructive shock resistance reaches 1,000 m/s² maximum and malfunction shock resistance reaches 500 m/s² maximum. The cross roller is the main mechanical distinction, supporting directional movement across the actuator rather than direct axial contact. These characteristics suit machine travel and position sensing where rolling contact and a 125 VAC general-load rating are required together. The source does not provide durability or contact-resistance values for this row. For a related D4C model using a standard roller plunger with the same 5 A at 125 VAC rating, see the D4C-2232 model.
