Omron WLCA2-2NLD-N Limit Switch
Omron WLCA2-2NLD-N is a two-circuit limit switch with an R38 mm roller lever for accurate machine position sensing. The roller actuator supports smooth contact with cams, slides, and moving mechanisms, while screw terminals with a G½ conduit entry simplify field wiring. A built-in LED provides visual confirmation of switch operation, and the 20° maximum pretravel gives a defined lever movement before switching. IP67 protection supports industrial use. The WLCA2-2NLD-N belongs to the WL Series within the industrial roller lever switch range from Omron control and automation products for dependable machine position and travel detection.

The Omron WLCA2-2NLD-N Limit Switch uses an R38 mm roller lever actuator for precise position detection on moving industrial equipment. The roller lever supports smooth mechanical contact with cams, slides, and machine mechanisms, while the 20° maximum pretravel provides a defined movement before switching. Screw terminals with a G½ conduit entry simplify field wiring, and a built-in LED operation indicator gives technicians quick visual confirmation of switch status. The model supports microloads down to 5 VDC at 1 mA resistive load and operates across 10 to 115 VAC/DC. IP67 protection supports installations exposed to dust, water, and demanding factory conditions.
Insulation resistance is 100 MΩ minimum at 500 VDC, while initial built-in switch contact resistance is 25 mΩ maximum. Operating temperature ranges from -10 to 80°C with 35 to 95% relative humidity. The WLCA2-2NLD-N withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 300 m/s², with malfunction vibration resistance from 10 to 55 Hz at 1.5 mm double amplitude. These characteristics support reliable roller-lever sensing, low-level switching, and visible operation feedback in machine automation. For a closely related WL model using the same R38 mm roller lever with 25±5° pretravel, see the WLCA2-2LD-N model.
