Omron WLNJ-30LD-N Limit Switch
Omron WLNJ-30LD-N combines a 4.8 mm diameter coil spring actuator with screw terminals and a G½ conduit entry. Pretravel is specified at 20±10 mm, and an LED provides operation indication. The source lists a 5 VDC, 1 mA resistive minimum load together with 10 to 115 VAC/DC for the indicator circuit. IP67 protection, 100 MΩ minimum insulation resistance, and 25 mΩ maximum initial contact resistance are included. The WLNJ-30LD-N belongs to the WL Series within the coil spring limit switch range from Omron switching products. Its 4.8 mm coil spring and LED distinguish this model.

The Omron WLNJ-30LD-N Limit Switch is fitted with a 4.8 mm diameter coil spring actuator and screw terminals with a G½ conduit connection. Pretravel is specified at 20±10 mm. An LED operation indicator is included, with an indicator range of 10 to 115 VAC/DC. The minimum applicable resistive load is listed as 5 VDC at 1 mA. Approximate indicator current is 0.4 mA at 10 VAC/DC and 0.5 mA at 115 VAC/DC. IP67 protection and 100 MΩ minimum insulation resistance at 500 VDC are specified.
Initial contact resistance is 25 mΩ maximum. The model operates from -10 to 80°C with relative humidity from 35 to 95%. Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude, while shock resistance is 1,000 m/s² minimum for destruction and 300 m/s² minimum for malfunction. The 4.8 mm spring and LED are useful when differentiating this version from another coil-spring WL model without an indicator. For the 6.5 mm spring version, see the WLNJ-55-N.
