Omron WLCA2-55-N Limit Switch
Omron WLCA2-55-N is a WL Series limit switch with an R38 mm roller lever, screw terminals, and a G½ conduit connection. It is supplied without an operation indicator and has a pretravel specification of 15±5°. The switch is listed with IP67 protection, 100 MΩ minimum insulation resistance, and 25 mΩ maximum initial contact resistance. The WLCA2-55-N belongs to the WL Series within the R38 roller lever limit switch range from Omron switching products. Its screw-terminal connection and absence of an indicator are key configuration details.

The Omron WLCA2-55-N Limit Switch uses an R38 mm roller lever with screw terminals and a G½ conduit connection. Pretravel is specified at 15±5°, and the model is explicitly listed without an operation indicator. IP67 protection is provided, while insulation resistance is 100 MΩ minimum at 500 VDC and initial contact resistance is 25 mΩ maximum. Operating temperature covers -10 to 80°C without icing, with relative humidity from 35 to 95%. The source also lists 50/60 Hz operation.
Malfunction vibration resistance ranges from 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. These values are shared by several WL models, making the R38 lever, screw-terminal G½ connection, and lack of an indicator the most useful distinguishing details. For an R38 version using a pre-wired threaded M12 connector instead, see the WLCA2-55LD-M1GJ-N.
