Omron WLCA2-2LD-N Limit Switch
Omron WLCA2-2LD-N is a two-circuit limit switch with an R38 mm roller lever for precise mechanical position detection. The roller lever provides smooth actuation from cams and moving machine parts, while screw terminals with a G½ conduit entry support field wiring. A built-in LED provides clear operating-status feedback during commissioning and maintenance, and the switch supports low-level control signals. IP67 protection suits demanding factory environments. The WLCA2-2LD-N belongs to the WL Series within the roller lever limit switch range from Omron machine automation products for reliable position, motion, and end-of-travel detection.

The Omron WLCA2-2LD-N Limit Switch uses an R38 mm roller lever actuator for repeatable mechanical position detection on industrial machinery. The roller lever provides smooth contact with moving cams, slides, and machine parts, while a pretravel of 25±5° gives a defined movement before switching. Screw terminals with a G½ conduit entry support practical field wiring, and the built-in LED operation indicator provides clear visual status during setup, inspection, or troubleshooting. The switch supports microloads down to 5 VDC at 1 mA resistive load and operates across 10 to 115 VAC/DC. IP67 protection helps the unit withstand demanding factory environments.
Insulation resistance is 100 MΩ minimum at 500 VDC, while initial contact resistance of the built-in switch is 25 mΩ maximum. The WLCA2-2LD-N operates from -10 to 80°C with 35 to 95% relative humidity. Destructive shock resistance is at least 1,000 m/s², with malfunction shock resistance of at least 300 m/s². Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. These characteristics combine roller-lever actuation, microload switching, LED indication, and sealed IP67 protection for machine position and travel detection. For a closely related WL model with the same R38 mm roller lever and different pretravel specification, see the WLCA2-2NLD-N model.
