Omron D4C-1301 Limit Switch
Omron D4C-1301 is a general-purpose limit switch with a 10 mm stainless steel pin plunger for direct mechanical position detection. The straight plunger suits stops, slides, and moving parts that approach the actuator head-on, while the SPDT contact form provides changeover switching for general loads. It is rated for 5 A at 250 VAC and 4 A at 30 VDC and comes prewired with a 5 m VCTF oil-resistant cable for extended routing from the sensing point. IP67 protection supports enclosed installations. The D4C-1301 belongs to the D4C Series within the pin plunger limit switch range from Omron control components for direct travel and end-position sensing.

The Omron D4C-1301 Limit Switch uses a 10 mm stainless steel pin plunger for direct machine position and end-of-travel detection. The straight actuator suits stops, slides, and moving parts that approach the switch head-on, while the SPDT contact form provides changeover switching for general loads. Electrical ratings are 5 A at 250 VAC and 4 A at 30 VDC. The switch is prewired with a 5 m VCTF oil-resistant cable, allowing the sensing point to be located away from the control connection. IP67 protection supports enclosed installations where dust, water, or oil may reach the switch body.
Mechanical durability is specified at 10 million operations minimum, while electrical durability reaches 200,000 operations minimum at 5 A, 125 VAC. Initial contact resistance is 400 mΩ maximum, and insulation resistance is 100 MΩ minimum at 500 VDC. The D4C-1301 operates from -10 to 70°C with 35 to 95% relative humidity. Destructive shock resistance reaches 1,000 m/s² maximum, while malfunction shock resistance reaches 500 m/s² maximum. Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. These characteristics suit direct plunger sensing where a long prewired cable is useful. For a related D4C model using a cross roller plunger instead of a pin plunger, see the D4C-1303 model.
