Omron D4C-2220 Limit Switch
Omron D4C-2220 is a general-purpose limit switch with an R38 roller lever using a 17.5 mm × 7 mm sintered stainless steel roller for machine travel and position detection. The lever actuator provides rolling contact with cams and moving parts that sweep 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 supports the enclosed switch body. The D4C-2220 belongs to the D4C Series within the R38 roller lever switch range from Omron control products for machine position, travel, and end-point sensing.

The Omron D4C-2220 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 allows moving cams or components to sweep across the roller instead of making direct axial contact. Its SPDT contact form provides changeover switching for general loads, and the source specifies a rating of 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-2220 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-lever position sensing where a wider target approach path is preferred over direct plunger contact. The R38 lever radius and stainless steel roller are the main actuator details for model selection. For a related D4C model using a roller plunger with the same 5 A at 125 VAC rating, see the D4C-2232 model.
