Omron WLCA12-LE-N Limit Switch
Omron WLCA12-LE-N uses an adjustable roller lever with an R25 to 89 mm adjustment range and screw terminals with a G½ conduit. A neon operation indicator is provided for 125 to 250 VAC, while the source also lists a 5 VDC, 1 mA resistive microload rating. Pretravel is specified at 15±5°. The WLCA12-LE-N belongs to the WL Series within the adjustable roller lever switch range from Omron limit switch products. IP67 protection and 100 MΩ minimum insulation resistance are included in its listed specifications.

The Omron WLCA12-LE-N Limit Switch uses an adjustable roller lever covering an R25 to 89 mm range. Electrical connection is through screw terminals with a G½ conduit, and pretravel is specified at 15±5°. A neon operation indicator is included, with lamp operation specified from 125 to 250 VAC. Approximate lamp current is 0.6 mA at 125 VAC and 1.9 mA at 250 VAC. The source also gives a 5 VDC, 1 mA resistive microload rating at P level. IP67 protection and 100 MΩ minimum insulation resistance at 500 VDC are listed.
Initial contact resistance is 25 mΩ maximum. Operating temperature ranges from -10 to 80°C with relative humidity between 35 and 95%. Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. Shock resistance is specified at 1,000 m/s² minimum for destruction and 300 m/s² minimum for malfunction. Adjustable lever radius and the neon indicator are the strongest model-specific details. For a fixed R38 roller-lever WL switch without an operation indicator, see the WLCA2-55-N.
