Omron WLCA12-2LD-N Limit Switch
Omron WLCA12-2LD-N is a two-circuit limit switch with an adjustable roller lever from R25 to R89 mm for flexible machine position detection. The adjustable actuator reach helps match different target paths and mounting distances, while screw terminals with a G½ conduit entry support practical field wiring. A built-in LED provides quick visual confirmation of switch operation, and low-level switching capability supports signal circuits. IP67 protection suits demanding industrial environments. The WLCA12-2LD-N belongs to the WL Series within the adjustable roller lever switch range from Omron automation products for accurate machine position and travel sensing.

The Omron WLCA12-2LD-N Limit Switch uses an adjustable roller lever that can be set from R25 to R89 mm, allowing the actuator reach to match different target paths and mounting distances. This flexibility suits conveyors, machine tools, transfer systems, and mechanisms where the contact point varies by installation. Screw terminals with a G½ conduit entry support field wiring, while a built-in LED operation indicator provides visible switch-status feedback during setup and maintenance. The model supports microloads down to 5 VDC at 1 mA resistive load and operates across 10 to 115 VAC/DC. IP67 protection supports demanding industrial environments.
Pretravel is specified at 25±5°, providing a defined lever movement before switching. Insulation resistance is 100 MΩ minimum at 500 VDC, while initial contact resistance of the built-in switch is 25 mΩ maximum. The WLCA12-2LD-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 vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. These characteristics support adjustable roller-lever position sensing with visual indication and low-level switching.
