Omron WLCA12-2-N Limit Switch
Omron WLCA12-2-N is a two-circuit limit switch with an adjustable roller lever from R25 to R89 mm for flexible machine position detection. The adjustable reach helps align the actuator with different target paths and mounting distances, while screw terminals with a G½ conduit entry support secure field wiring. Its 25±5° pretravel provides a defined lever movement, and this version is supplied without an operation indicator. IP67 protection and operation from -10 to 80°C support demanding factory environments. The WLCA12-2-N belongs to the WL Series within the adjustable roller lever limit switch range from Omron automation products for dependable machine position and travel sensing.

The Omron WLCA12-2-N Limit Switch uses an adjustable roller lever from R25 to R89 mm for flexible machine position detection. The adjustable reach allows the actuator to be aligned with different target paths and mounting distances, making it useful on conveyors, machine tools, lifts, and moving mechanisms. Screw terminals with a G½ conduit entry support secure field wiring, while 25±5° pretravel provides a defined lever movement before switching. This version is supplied without an operation indicator, making it suitable where visual status feedback is handled elsewhere. IP67 protection supports demanding industrial environments exposed to dust or moisture.
Insulation resistance is 100 MΩ minimum at 500 VDC, while initial contact resistance of the built-in switch is 25 mΩ maximum. The WLCA12-2-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 adjustable roller-lever sensing where actuator reach, sealed construction, and screw-terminal wiring are important for varied machine layouts and target positions.
