Omron WLCA2-2N-N Limit Switch
Omron WLCA2-2N-N is a two-circuit limit switch with an R38 mm roller lever for accurate machine position detection. The roller actuator suits cams, slides, and moving mechanisms that pass across the lever, while screw terminals with a G½ conduit entry simplify field wiring. A 20° maximum pretravel gives a defined movement before switching, and this version is supplied without an operation indicator for installations where status feedback is handled externally. IP67 protection supports demanding industrial environments. The WLCA2-2N-N belongs to the WL Series within the industrial roller lever switch range from Omron machine automation products for dependable position and travel sensing.

The Omron WLCA2-2N-N Limit Switch uses an R38 mm roller lever for repeatable position and travel detection in industrial equipment. The roller lever suits cams, slides, conveyors, and moving machine parts that sweep across the actuator, while screw terminals with a G½ conduit entry simplify field wiring. A 20° maximum pretravel provides a defined lever movement before switching. This version is supplied without an operation indicator, making it useful where switch status is monitored elsewhere in the control system. IP67 protection supports demanding factory environments exposed to dust, water, or other common contaminants.
Insulation resistance is 100 MΩ minimum at 500 VDC, while initial contact resistance of the built-in switch is 25 mΩ maximum. The WLCA2-2N-N operates from -10 to 80°C with 35 to 95% relative humidity. Destructive shock resistance is at least 1,000 m/s² and malfunction shock resistance is at least 300 m/s². Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. These characteristics make the model suitable for robust roller-lever sensing where sealed construction, field wiring flexibility, and a shorter pretravel are required in automation machinery. For a related WL roller-lever model using the same R38 mm actuator with 15±5° pretravel, see the WLCA2-N model.
