Omron D4C-3201 Limit Switch
Omron D4C-3201 is a general-purpose limit switch with a 10 mm stainless steel pin plunger for direct machine position detection. The straight actuator suits stops, slides, fixtures, and moving parts that approach the switch head-on, providing a clear switching point. Its SPDT contact form supports changeover control, while the 4 A at 30 VDC rating suits standard DC machine circuits. IP67 protection helps the switch withstand dust, water, and demanding factory environments. The D4C-3201 belongs to the D4C Series within the pin plunger limit switch range from Omron automation components for reliable machine position and end-of-travel detection.

The Omron D4C-3201 Limit Switch uses a 10 mm stainless steel pin plunger for direct mechanical position detection in general-purpose industrial machinery. The straight plunger is suited to applications where a moving part approaches the switch head-on, such as machine stops, slides, jigs, and end-of-travel mechanisms. Its SPDT contact form provides changeover switching for control circuits, with a 4 A at 30 VDC rating for general loads. Inrush current capability reaches 20 A maximum on the NC side and 10 A maximum on the NO side. IP67 protection helps the switch withstand dust, water, and demanding factory conditions, while the stainless steel actuator supports repeated mechanical contact.
The D4C-3201 operates from -10 to 70°C with 35 to 95% relative humidity and is specified for pollution degree 3 under EN 60947-5-1. Shock resistance reaches 1,000 m/s² maximum for destruction and 500 m/s² maximum for malfunction. The switch is Class I and includes an earth wire, supporting protective grounding in the installation. These specifications make it a practical choice where compact direct-plunger detection, sealed industrial protection, and clear end-position switching are required. Its straight actuator path also suits repeatable machine stops where lateral movement is minimal. For another D4C model using a sealed stainless steel pin plunger with closely related switching characteristics, see the D4C-1631 model.
