Omron WLNJ-N Limit Switch
Omron WLNJ-N Limit Switch uses a 6.5 mm diameter coil spring actuator with screw terminals and a G½ conduit size. The model is supplied without an operation indicator and has a listed pretravel of 20±10 mm. Electrical characteristics include 25 mΩ max. initial contact resistance for the built-in switch, 100 MΩ min. insulation resistance at 500 VDC, and 50/60 Hz frequency. IP67 protection is specified with an operating temperature range of -10 to +80°C with no icing and 35 to 95% RH. Malfunction vibration is listed at 10 to 55 Hz with 1.5 mm double amplitude. The WLNJ-N belongs to the WL Series within the Omron Limit Switch range from Omron.

The Omron WLNJ-N Limit Switch uses a coil spring actuator with a stated diameter of 6.5 mm. Its connection format is screw terminals with a G½ conduit size, and the model is supplied without an operation indicator. The listed pretravel value is 20±10 mm. Electrical characteristics include 25 mΩ max. initial contact resistance for the built-in switch, 100 MΩ min. insulation resistance at 500 VDC, and 50/60 Hz frequency. These values identify the WLNJ-N through its coil-spring actuator, screw-terminal arrangement, conduit size, pretravel, indicator configuration, contact resistance, insulation resistance, and frequency. The 6.5 mm figure belongs to the coil spring diameter, while the 20±10 mm figure is the separate pretravel specification supplied for this WL Series model.
Environmental specifications include IP67 protection, an operating temperature range of -10 to +80°C with no icing, and 35 to 95% RH. Malfunction vibration is listed at 10 to 55 Hz with 1.5 mm double amplitude. Shock values are 1,000 m/s² min. for destruction and 300 m/s² min. for malfunction. The source therefore provides a clear combination of actuator, connection, pretravel, resistance, enclosure, temperature, humidity, vibration, and shock data without specifying an application. For another WLNJ model with a coil-spring actuator in the IndMALL product set, see the WLNJ-30-N.
