Omron D4C-1202 Limit Switch
Omron D4C-1202 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, conveyors, and moving workpieces that pass across the sensing point, while the SPDT contact form provides changeover switching for general loads. Electrical ratings of 5 A at 250 VAC and 4 A at 30 VDC support common industrial control circuits, and IP67 protection suits demanding factory environments. The D4C-1202 belongs to the D4C Series within the roller plunger limit switch range from Omron automation components for dependable machine travel and end-position detection.

The Omron D4C-1202 Limit Switch uses a 12 mm × 4.4 mm sintered stainless steel roller plunger for repeatable mechanical position detection. The rolling actuator suits cams, slides, conveyors, and workpieces that move across the sensing point, reducing direct sliding contact during frequent operation. Its SPDT contact form provides changeover switching for general loads, with ratings of 5 A at 250 VAC and 4 A at 30 VDC. Inrush current capability reaches 20 A maximum on the NC side and 10 A maximum on the NO side. IP67 protection supports demanding factory installations where dust, water, or other contaminants may be present.
The D4C-1202 operates from -10 to 70°C with 35 to 95% relative humidity and is specified for pollution degree 3 under EN60947-5-1. It is a Class I device with an earth wire for grounded machine installations. Destructive shock resistance reaches 1,000 m/s² maximum, while malfunction shock resistance reaches 500 m/s² maximum. These characteristics make the model suitable for roller-plunger travel and end-position sensing where general-load switching, sealed protection, and durable stainless steel contact are important. The actuator is particularly useful when moving targets pass across the switch instead of pressing straight into a pin plunger. For a related D4C model using a sealed roller plunger, see the D4C-1232 model.
