Omron WLNJ-LD-N Limit Switch
Omron WLNJ-LD-N is a WL Series limit switch with a 6.5 mm diameter coil spring actuator, screw terminals, and a G½ conduit. It includes an LED operation indicator and lists a minimum applicable load of 5 VDC at 1 mA for a resistive load at P level. The indicator range is 10 to 115 VAC/DC. The WLNJ-LD-N LED Coil Spring Switch belongs to the WL Series within the Omron Coil Spring Limit Switch Range from Omron Control Switch Products. IP67 protection, 25 mΩ maximum initial contact resistance, and 100 MΩ minimum insulation resistance at 500 VDC are specified.

The Omron WLNJ-LD-N Limit Switch uses a 6.5 mm diameter coil spring actuator with screw terminals and a G½ conduit. An LED operation indicator is included. The minimum applicable load is 5 VDC at 1 mA for a resistive load at P level, while the indicator range is 10 to 115 VAC/DC. Approximate indicator current is 0.4 mA at 10 VAC/DC and 0.5 mA at 115 VAC/DC. Initial contact resistance is 25 mΩ maximum, insulation resistance is 100 MΩ minimum at 500 VDC, frequency is 50/60 Hz, and IP67 protection is specified.
Operating temperature ranges from -10 to 80°C with no icing, and relative humidity is 35 to 95%. Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. Destructive shock resistance is 1,000 m/s² minimum and malfunction shock resistance is 300 m/s² minimum. A 20±10 mm value is present in the structured row, but its visible column label is not supplied in the extract, so no function is assigned to that value. The main model terms remain 6.5 mm coil spring, G½ screw terminals, LED indicator, 5 VDC 1 mA minimum applicable load, 10 to 115 VAC/DC indicator range, and IP67 protection. For a related WL coil-spring model with LED indication, see WLNJ-30LD-N.
