The Omron WLSD-N is a rugged two-circuit limit switch designed for industrial automation environments that require precise mechanical actuation. It features a horizontal plunger actuator and screw terminal connections with a G½ conduit size. With a pretravel distance of 2.8 mm max. and wide compatibility for installation, the WLSD-N is built for consistent performance under repeated operations.
It operates within an ambient temperature range of –10°C to +80°C and humidity from 35% to 95% RH, with no icing or condensation. The switch withstands vibration (10–55 Hz, 1.5 mm amplitude) and shock (1,000 m/s² destruction), making it ideal for use in heavy-duty environments. The built-in switch ensures low contact resistance (25 mΩ max.) and high insulation resistance (100 MΩ min. at 500 VDC). The WLSD-N is housed in a sealed enclosure rated for IP67 protection.
