Omron D4MC-5000 Limit Switch
Omron D4MC-5000 is a panel-mount limit switch with an 8.4 mm stainless steel plunger for direct mechanical position detection in compact industrial equipment. The panel-mount design allows the actuator to project through a machine surface, while the straight plunger suits stops, slides, fixtures, and moving parts that approach the switch head-on. Its SPDT contact form provides changeover switching for general loads, and IP67 protection supports environments exposed to dust or moisture. Operation from -10 to 80°C supports varied factory conditions. The D4MC-5000 belongs to the D4MC Series within the panel-mount plunger limit switch range from Omron machine control products for reliable position and end-of-travel sensing.

The Omron D4MC-5000 Limit Switch uses an 8.4 mm stainless steel panel-mount plunger for direct, repeatable mechanical position detection in compact industrial equipment. The panel-mount format allows the actuator to project through a machine surface, while the straight plunger suits stops, slides, fixtures, and moving parts that approach the sensing point head-on. Its SPDT contact form provides changeover switching for general loads at 50/60 Hz. IP67 protection supports factory environments exposed to dust or moisture, while operation from -10 to 80°C suits a broad range of machine conditions and repeated actuation.
The D4MC-5000 provides at least 10 million mechanical operations and 500,000 electrical operations, supporting frequent switching over a long service life. Initial contact resistance is 15 mΩ maximum, and insulation resistance is 100 MΩ minimum at 500 VDC. The switch operates with 35 to 95% relative humidity and is specified for pollution degree 3 under IEC947-5-1. Destructive shock resistance reaches 1,000 m/s² maximum, while malfunction shock resistance reaches 100 m/s² maximum. These characteristics support direct panel-mount plunger sensing where compact installation, SPDT switching, and sealed construction are required in automation.
