Omron WLCA2-2-N Limit Switch
Omron WLCA2-2-N is a two-circuit limit switch with an R38 mm roller lever for reliable machine position and end-of-travel detection. The roller lever suits cams, slides, and moving mechanisms that sweep across the actuator, while screw terminals with a G½ conduit entry support secure field wiring. Its 25±5° pretravel provides a defined lever movement before switching, and this version is supplied without an operation indicator. IP67 protection and operation from -10 to 80°C support demanding factory environments. The WLCA2-2-N belongs to the WL Series within the roller lever limit switch range from Omron automation products for dependable industrial position sensing.

The Omron WLCA2-2-N Limit Switch uses an R38 mm roller lever for mechanical position and end-of-travel detection in industrial machinery. The lever actuator suits cams, slides, conveyors, and moving mechanisms that sweep across the roller, providing smooth and repeatable actuation. Screw terminals with a G½ conduit entry support secure field wiring, while the 25±5° pretravel gives a defined lever movement before switching. This version is supplied without an operation indicator, making it suitable where visual status feedback is handled externally. IP67 protection supports demanding factory environments exposed to dust or moisture.
Electrical integrity is supported by insulation resistance of 100 MΩ minimum at 500 VDC and initial contact resistance of 25 mΩ maximum for the built-in switch. The WLCA2-2-N operates from -10 to 80°C with 35 to 95% relative humidity. It withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 300 m/s², while malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. These characteristics support reliable roller-lever position sensing where sealed construction, screw-terminal wiring, and defined angular movement are important. For a closely related WL model with the same R38 mm roller lever and a 20° maximum pretravel, see the WLCA2-2N-N model.
