Omron WLCA12-2N-N Limit Switch
Omron WLCA12-2N-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 match different target paths and mounting distances, while screw terminals with a G½ conduit entry support secure field wiring. This version is supplied without an operation indicator, making it suitable where visual status feedback is handled elsewhere in the control system. IP67 protection and operation from -10 to 80°C support demanding industrial environments. The WLCA12-2N-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 WLCA12-2N-N Limit Switch uses 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, mounting distances, and machine layouts, making it useful on conveyors, transfer systems, and moving mechanisms. Screw terminals with a G½ conduit entry support secure field wiring, while this version is supplied without an operation indicator. Maximum pretravel is 20°, providing a defined lever movement before switching. IP67 protection supports demanding industrial environments, and the switch operates from -10 to 80°C with 35 to 95% relative humidity.
Electrical integrity is supported by insulation resistance of 100 MΩ minimum at 500 VDC and initial built-in switch contact resistance of 25 mΩ maximum. The WLCA12-2N-N withstands destructive shock of at least 1,000 m/s² and malfunction shock of at least 300 m/s². Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude, with operation at 50/60 Hz. These characteristics make the model suitable where adjustable roller reach, sealed construction, screw-terminal wiring, and simple non-indicating operation are preferred. The R25 to R89 mm adjustment range is its main application advantage within the WL family. For a related adjustable roller-lever model with LED operation indication, see the WLCA12-2NLD-N model.
