The Omron WLNJ-30LD-N is a compact two-circuit limit switch built for precision detection in harsh industrial environments. It features a 4.8 mm coil spring actuator and screw terminals with a G½ conduit for secure wiring. This model includes a built-in LED indicator for quick operation visibility and supports both AC and DC voltages from 10 to 115 V.
Designed for microload switching, it handles signals as low as 5 VDC at 1 mA and has low leakage current (0.4–0.5 mA typical). It operates at frequencies up to 50/60 Hz and offers a pretravel distance of 20 ±10 mm. Withstanding vibration (10–55 Hz) and shock (up to 1,000 m/s²), the WLNJ-30LD-N delivers stable performance in high-reliability applications such as conveyors, machine tools, and sensors. The switch operates between –10°C to 80°C with up to 95% humidity and is housed in a sealed body with IP67 protection.
