The Omron WLCA12-N is a rugged two-circuit limit switch designed for precision detection in industrial environments. It features an adjustable roller lever actuator (R25 to 89 mm) for flexible mechanical positioning and control. The switch is equipped with screw terminals and a GΒ½ conduit entry for secure wiring and easy installation.

With a rated insulation resistance of 100 MΩ (at 500 VDC) and contact resistance of 25 mΩ max, it ensures reliable electrical connectivity. Operating temperatures range from βˆ’10Β°C to +80Β°C with up to 95% humidity. The switch handles vibration (10–55 Hz, 1.5 mm double amplitude) and shock loads up to 1,000 m/sΒ² during destruction testing, making it suitable for harsh settings.

Durable and compact, the WLCA12-N is ideal for use in conveyors, machinery, and safety mechanisms requiring dependable operation and long-term durability with IP67 protection.
