Omron WLNJ-30-N Limit Switch
Omron WLNJ-30-N Limit Switch uses a 4.8 mm coil spring actuator with screw terminals and a G½ conduit size. The model is supplied without an operation indicator and has a 20±10 mm pretravel value. Its listed electrical characteristics include 50/60 Hz frequency, 25 mΩ max. initial contact resistance for the built-in switch, and 100 MΩ min. insulation resistance at 500 VDC. IP67 protection, an operating temperature range of -10 to +80°C with no icing, and 35 to 95% RH are specified for this configuration. The WLNJ-30-N belongs to the WL Series within the Omron Limit Switch range from Omron.

The Omron WLNJ-30-N Limit Switch uses a coil spring actuator with a 4.8 mm diameter. Its terminal arrangement is specified as 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 data includes 50/60 Hz frequency, 25 mΩ max. initial contact resistance for the built-in switch, and 100 MΩ min. insulation resistance at 500 VDC. These values identify the WLNJ-30-N by actuator type, terminal method, pretravel, indicator configuration, and the electrical characteristics provided for the built-in switch. The screw-terminal form and G½ conduit specification describe the connection format, while the coil spring remains the listed actuator for this configuration.
For environmental specifications, the WLNJ-30-N is rated IP67 and is listed for operation from -10 to +80°C with no icing and 35 to 95% RH. Malfunction vibration is specified at 10 to 55 Hz with 1.5 mm double amplitude. Shock specifications are 1,000 m/s² min. for destruction and 300 m/s² min. for malfunction. These values place the actuator, connection, electrical resistance, enclosure, temperature, humidity, vibration, and shock characteristics together for clear model identification. For another WL Series model using a flexible rod actuator, see the WLNJ-2-N.
