The Omron WLCA12-2-N is a heavy-duty limit switch designed for industrial motion control and mechanical positioning. It features an adjustable roller lever actuator with a sensing range between R25 and R89 mm, allowing precise mechanical tuning for various machine configurations. The switch supports screw terminal wiring and uses a G½ conduit for secure field connections.
With a pretravel of 25±5°, this switch is suited for moderate-speed actuation and operates reliably across a wide temperature range from –10°C to +80°C. It withstands vibration (10–55 Hz, 1.5 mm double amplitude) and shock up to 1,000 m/s². Built without an operation indicator, the WLCA12-2-N prioritizes sealed construction and long-term mechanical reliability. Insulation resistance is rated at 100 MΩ, and contact resistance at 25 mΩ or less. Ideal for machine tools, lifts, and heavy equipment, it is enclosed in a durable housing with certified IP67 protection.
