The Omron WLCA2-55-N is a heavy-duty limit switch designed for precision detection in industrial environments. It features a roller lever with a 38 mm radius and supports dual-circuit switching for enhanced control versatility. The switch uses screw terminals with a G½ conduit size and operates at standard 50/60 Hz frequencies. With a pretravel of 15±5°, it provides consistent and repeatable actuation in automated machinery and conveyor systems.
This model operates reliably across a wide temperature range from –10°C to +80°C and in humidity levels up to 95% RH. It delivers strong resistance to vibration (10–55 Hz, 1.5 mm amplitude) and shock (up to 1,000 m/s² destruction, 300 m/s² malfunction). With a minimum insulation resistance of 100 MΩ and low contact resistance, the WLCA2-55-N ensures signal integrity. Its rugged design and sealed housing meet the requirements for long-term use in harsh settings, backed by IP67 protection.
