Omron WLCAL4-LD-N Limit Switch
Omron WLCAL4-LD-N is a WL Series limit switch with an adjustable rod lever measuring 350 to 380 mm, 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 WLCAL4-LD-N LED Rod Lever Switch belongs to the WL Series within the Omron Adjustable Rod Limit Switch Range from Omron Automation Component Range. IP67 protection and 25 mΩ maximum initial contact resistance are also listed.

The Omron WLCAL4-LD-N Limit Switch uses an adjustable rod lever specified from 350 to 380 mm, 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. The indicator range is 10 to 115 VAC/DC, with approximate current of 0.4 mA at 10 VAC/DC and 0.5 mA at 115 VAC/DC. Initial contact resistance is 25 mΩ maximum and insulation resistance is 100 MΩ minimum at 500 VDC. IP67 protection is specified, and frequency is listed at 50/60 Hz.
Operating temperature ranges from -10 to 80°C with no icing, with relative humidity from 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. The source also lists a 15±5° value, but the supplied extract does not show its field label, so no separate function is assigned to it. The clearest model terms are adjustable rod lever 350 to 380 mm, G½ screw terminals, LED operation indicator, 5 VDC 1 mA minimum applicable load, 10 to 115 VAC/DC indicator range, 25 mΩ contact resistance, and IP67 protection.
