The Omron WLCA2-2-N is a rugged limit switch built for industrial equipment requiring two-circuit control and mechanical durability. It features a roller lever actuator with a 38 mm radius and operates with a pretravel angle of 25±5°, suitable for general-purpose machine actuation. The unit includes screw terminals with a G½ conduit entry, allowing easy and secure wiring.
Designed for harsh operating environments, it functions reliably across a wide temperature range from −10°C to 80°C and humidity up to 95% RH. It offers high insulation resistance (100 MΩ min. at 500 VDC), low contact resistance (25 mΩ max.), and endures vibration and shock loads commonly found in automated systems. Built without an operation indicator, the WLCA2-2-N is designed for long-term performance and resistance to contamination in production lines, conveyors, and mechanical linkages. The switch is housed in a sealed enclosure that meets IP67 protection standards.
