The Omron WLCA2-2N-N is a robust limit switch designed for two-circuit control applications. It features a roller lever with a 38 mm radius for smooth actuation and screw terminals with G½ conduit compatibility for secure electrical connections. With a pretravel angle of 20° max and durable internal components, it ensures reliable position detection in automation systems and machinery.
Engineered for performance under demanding conditions, it supports a wide ambient temperature range from –10°C to +80°C and up to 95% relative humidity. The switch exhibits strong vibration resistance (10–55 Hz, 1.5 mm double amplitude) and shock resistance (1,000 m/s² destruction, 300 m/s² malfunction). With insulation resistance ≥100 MΩ and contact resistance ≤25 mΩ, the WLCA2-2N-N delivers reliable signal transmission in control circuits. Its sealed housing is rated IP67, making it suitable for dusty, wet, or outdoor environments where protection is critical.
