The Omron WLCA12-LE-N is a durable limit switch designed for precise position detection in industrial machinery. It features an adjustable roller lever actuator (R25 to 89 mm), a built-in neon lamp indicator for operation status, and screw terminals with a G½ conduit for easy installation. The switch supports two-circuit control, ideal for applications that require dual output or safety redundancy.
Rated for voltages between 125 to 250 VAC, it can handle microloads down to 5 VDC, 1 mA (P level). The unit provides excellent insulation (100 MΩ min. at 500 VDC) and low contact resistance (25 mΩ max.). Operating temperatures range from –10°C to +80°C, with a wide humidity tolerance of 35% to 95% RH. It is vibration-resistant (10–55 Hz) and withstands shocks up to 1,000 m/s². The WLCA12-LE-N is built to perform reliably in demanding environments with IP67 protection.
