The Omron WLNJ-LD-N is a precision two-circuit limit switch designed for low-load switching applications in harsh industrial environments. It features a 6.5 mm diameter coil spring actuator and screw terminals with a G½ conduit size for reliable wiring. The switch operates at low voltages from 10 to 115 VAC/DC and supports microloads down to 5 VDC, 1 mA (P level).
An integrated LED provides clear visual confirmation of operation status. The unit offers a wide operating temperature range of –10°C to +80°C and supports up to 95% relative humidity. Withstand ratings include vibration (10–55 Hz) and shock (1,000 m/s² destruction, 300 m/s² malfunction), ensuring stable operation under mechanical stress. It maintains insulation resistance ≥100 MΩ and contact resistance ≤25 mΩ. The WLNJ-LD-N is ideal for precision feedback in compact machines and offers long-lasting performance with IP67 protection.
