Omron WLCA2-55LD-M1GJ-N Limit Switch
Omron WLCA2-55LD-M1GJ-N combines an R38 mm roller lever with a pre-wired threaded M12 connector. The source identifies this as a DC configuration with NO-only switching on terminals 1 and 4 and a pretravel specification of 15±5°. IP67 protection, 100 MΩ minimum insulation resistance, and 25 mΩ maximum initial contact resistance are listed. The WLCA2-55LD-M1GJ-N belongs to the WL Series within the M12 roller lever switch range from Omron control components. The M12 connection and NO terminal assignment are important model identifiers.

The Omron WLCA2-55LD-M1GJ-N Limit Switch combines an R38 mm roller lever with a pre-wired threaded M12 connector. The source identifies the electrical configuration as DC and NO only, with normally open terminals assigned to pins 1 and 4. Pretravel is specified at 15±5°. IP67 protection, 100 MΩ minimum insulation resistance at 500 VDC, and 25 mΩ maximum initial contact resistance are listed. Operating temperature extends from -10 to 80°C with relative humidity from 35 to 95%.
Vibration resistance for malfunction 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. The combination of R38 lever, M12 connector, DC designation, and NO pin assignment provides the clearest model identification. Another M12-connected R38 model in this batch uses a different NO terminal assignment. For that version, see the WLCA2-LD-M1J-N.
