Omron WLCA2-N Limit Switch
Omron WLCA2-N is a two-circuit limit switch with an R38 mm roller lever for repeatable machine position and end-of-travel detection. The lever actuator provides smooth contact with cams, slides, and moving machine parts, while screw terminals with a G½ conduit entry support practical field wiring. Its 15±5° pretravel gives responsive mechanical actuation, and the switch is supplied without an operation indicator where external status feedback is preferred. IP67 protection and operation from -10 to 80°C suit demanding factory conditions. The WLCA2-N belongs to the WL Series within the two-circuit roller lever switch range from Omron industrial control products for machine position sensing.

The Omron WLCA2-N Limit Switch uses an R38 mm roller lever for mechanical position and end-of-travel detection in industrial machinery. The roller actuator provides smooth contact with cams, slides, and moving parts that pass across the sensing point, while screw terminals with a G½ conduit entry support secure machine wiring. Its 15±5° pretravel provides responsive lever movement before switching. The switch is supplied without an operation indicator, making it suitable where visual feedback is not required at the sensing point. IP67 protection supports installation around dust, water, and demanding factory conditions.
Electrical characteristics include 100 MΩ minimum insulation resistance at 500 VDC and 25 mΩ maximum initial contact resistance for the built-in switch. The WLCA2-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 durable roller-lever sensing where compact angular movement, sealed construction, and screw-terminal wiring are important for repeated machine position and travel detection. For another WL model using the same R38 mm roller lever with a 25±5° pretravel, see the WLCA2-2-N model.
