Omron WLCA12-2NLD-N Limit Switch
Omron WLCA12-2NLD-N is a two-circuit limit switch with an adjustable roller lever from R25 to R89 mm for flexible 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. A built-in LED provides visible switch-status feedback during commissioning and maintenance, and microload capability supports low-level control circuits. IP67 protection suits demanding industrial installations. The WLCA12-2NLD-N belongs to the WL Series within the adjustable roller lever limit switch range from Omron automation products for accurate machine position and travel sensing.

The Omron WLCA12-2NLD-N Limit Switch uses an adjustable roller lever from R25 to R89 mm, allowing the actuator reach to match different target paths and machine layouts. This flexibility suits conveyors, transfer systems, machine tools, and mechanisms where the contact point varies by installation. Screw terminals with a G½ conduit entry support secure field wiring, while the built-in LED operation indicator provides quick visual status during setup and maintenance. The switch supports microloads down to 5 VDC at 1 mA resistive load and operates across 10 to 115 VAC/DC. Maximum pretravel is 20°, and IP67 protection supports industrial environments.
Insulation resistance is 100 MΩ minimum at 500 VDC, while initial contact resistance of the built-in switch is 25 mΩ maximum. The WLCA12-2NLD-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, with vibration resistance from 10 to 55 Hz at 1.5 mm double amplitude. These characteristics combine adjustable roller-lever sensing, microload switching, LED indication, and sealed construction for flexible machine position detection. For a closely related WL model with the same adjustable R25 to R89 mm roller lever and LED indication, see the WLCA12-2LD-N model.
