The Omron WLNJ-N is a durable limit switch built for demanding applications requiring two-circuit switching. It features a 6.5 mm diameter coil spring actuator for flexible mechanical engagement and a pretravel of 20±10 mm. The unit includes screw terminals with a G½ conduit size for secure wiring in industrial setups.
Designed for long-term reliability, the switch operates across a wide environmental range from –10°C to +80°C and 35–95% humidity. It withstands vibration (10–55 Hz, 1.5 mm amplitude) and shock up to 1,000 m/s² (destruction). Contact resistance is kept low at 25 mΩ (initial), and insulation resistance remains above 100 MΩ at 500 VDC, ensuring consistent signal integrity.
With no operation indicator and a simple, sealed structure, the WLNJ-N is suited for environments where space is limited and durability is critical. The housing provides complete dust and water resistance with a rating of IP67 protection.
