The Omron WLCA12-2NLD-N is a two-circuit limit switch featuring an adjustable roller lever with a sensing range of R25 to R89 mm. It is designed for use in automation systems requiring precise and reliable limit detection. The unit includes screw terminals with a G½ conduit entry, allowing secure and flexible wiring in industrial panels or machines.
Equipped with a built-in LED operation indicator, it offers quick visual status monitoring. The switch supports a wide operating voltage range of 10 to 115 VAC/DC and handles microloads as low as 5 VDC, 1 mA (P-level). It offers excellent insulation resistance (100 MΩ min.) and low contact resistance (25 mΩ max.). Operating in harsh conditions from −10°C to +80°C with high humidity (up to 95%), the WLCA12-2NLD-N withstands vibration and shock during operation. Its sealed construction ensures long-term field performance with IP67 protection.
