Omron WLCA2-LE-N Limit Switch
Omron WLCA2-LE-N uses an R38 mm roller lever with screw terminals and a G½ conduit connection. A neon lamp provides an operation indicator, while pretravel is specified at 15±5°. The source lists a 5 VDC, 1 mA resistive minimum load and lamp operation from 125 to 250 VAC. IP67 protection, 100 MΩ minimum insulation resistance, and 25 mΩ maximum initial contact resistance are specified. The WLCA2-LE-N belongs to the WL Series within the R38 roller lever switch range from Omron switching products. The neon indicator and screw-terminal connection distinguish this version.

The Omron WLCA2-LE-N Limit Switch uses an R38 mm roller lever together with screw terminals and a G½ conduit entry. Pretravel is specified at 15±5°. A neon lamp provides an operation indicator and is listed for 125 to 250 VAC, with approximate lamp currents of 0.6 mA at 125 VAC and 1.9 mA at 250 VAC. The minimum applicable load is 5 VDC at 1 mA for a resistive load at P level. IP67 protection, 100 MΩ minimum insulation resistance at 500 VDC, and 25 mΩ maximum initial contact resistance are specified.
Operating temperature covers -10 to 80°C with 35 to 95% relative humidity. Malfunction vibration resistance is 10 to 55 Hz at 1.5 mm double amplitude. Shock resistance is listed at 1,000 m/s² minimum for destruction and 300 m/s² minimum for malfunction. The fixed R38 lever and neon indication distinguish this version from adjustable or LED-equipped WL models. For an adjustable rod-lever model with LED indication and the same G½ screw-terminal format, see the WLCL-2NLD-N.
