Omron D4MC-2000 Limit Switch
Omron D4MC-2000 is a compact limit switch with a hinge roller lever using a stainless steel lever and 12.7 mm × 7.5 mm plastic roller for mechanical position detection. The hinged actuator suits cams, slides, and moving machine parts that sweep across the roller, providing smooth actuation where a direct plunger is not preferred. Its SPDT contact form supports changeover switching for general control loads, while IP67 protection and operation from -10 to 80°C support demanding factory environments. The D4MC-2000 belongs to the D4MC Series within the hinge roller lever limit switch range from Omron machine control products for reliable position and travel detection.

The Omron D4MC-2000 Limit Switch uses a hinge roller lever with a stainless steel lever and a 12.7 mm × 7.5 mm plastic roller for mechanical position detection. The hinged actuator suits cams, slides, conveyors, and moving machine parts that sweep across the roller, providing smooth actuation where a direct plunger is not preferred. Its SPDT contact form provides changeover switching for general loads at 50/60 Hz. IP67 protection helps the switch operate around dust, water, and common factory contaminants, while the -10 to 80°C operating range supports varied industrial environments and repeated machine cycles.
The D4MC-2000 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. These characteristics support hinge roller-lever position sensing where compact construction, sealed protection, and SPDT switching are required. The plastic roller offers smooth contact with moving targets while the stainless lever provides structural support.
