Omron WLNJ-2-N Limit Switch
Omron WLNJ-2-N Limit Switch uses a flexible rod actuator with screw terminals and a G½ conduit size. It is supplied without an operation indicator and has a listed pretravel value of 40±20 mm. 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. The model has IP67 protection and is specified for operation from -10 to +80°C with no icing and 35 to 95% RH. Vibration malfunction is listed at 10 to 55 Hz with 1.5 mm double amplitude, while shock values are also specified. The WLNJ-2-N belongs to the WL Series within the Omron Limit Switch range from Omron.

The Omron WLNJ-2-N Limit Switch uses a flexible rod actuator with screw terminals and a G½ conduit size. The model is supplied without an operation indicator and has a listed pretravel value of 40±20 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 define the WLNJ-2-N through its flexible rod actuator, terminal format, conduit size, pretravel, indicator configuration, frequency, contact resistance, and insulation resistance, giving the model a clear technical relationship to the wider WL Series through its stated mechanical and electrical attributes. The 40±20 mm value is the listed pretravel and is separate from the flexible rod actuator description.
Environmental specifications include IP67 protection, an operating temperature range of -10 to +80°C with no icing, and humidity from 35 to 95% RH. Malfunction vibration is 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. These details provide the listed enclosure and environmental limits alongside the actuator and electrical data. For a WLNJ model using a 4.8 mm coil spring actuator instead of the flexible rod listed here, see the WLNJ-30-N.
