Omron D4MC-5040 Limit Switch
Omron D4MC-5040 is a panel-mount limit switch with a 12.7 mm × 5 mm stainless steel roller plunger for accurate mechanical position detection. The panel-mount design supports compact integration through a machine surface, while the roller actuator provides smooth contact with cams, slides, and moving workpieces. Its SPDT contact form supports changeover switching for general control loads, and IP67 protection suits environments exposed to dust or moisture. Operation from -10 to 80°C and long mechanical durability support frequent machine cycles. The D4MC-5040 belongs to the D4MC Series within the panel-mount roller plunger switch range from Omron machine control products for dependable position and travel detection.

The Omron D4MC-5040 Limit Switch uses a 12.7 mm × 5 mm stainless steel panel-mount roller plunger for mechanical position detection. The panel-mount construction supports compact installation through a machine surface, while the rolling actuator provides smooth contact with cams, slides, and moving workpieces. Its SPDT contact form provides changeover switching for general control loads at 50/60 Hz. IP67 protection helps the switch operate around dust, water, and common factory contaminants. The -10 to 80°C operating range suits varied industrial environments, while the panel-mount roller arrangement is useful where the sensing point must project through a machine panel or bracket.
The D4MC-5040 provides at least 10 million mechanical operations and 500,000 electrical operations, supporting repeated actuation in automated equipment. Initial contact resistance is 15 mΩ maximum, while 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 combine compact panel mounting, roller-plunger actuation, SPDT switching, and sealed environmental protection for dependable machine position sensing. For another D4MC model using a hinge lever rather than a panel-mount roller plunger, see the D4MC-1000 model.
