The Omron WLCAL4-N is a long-range two-circuit limit switch equipped with an adjustable rod lever actuator measuring 350 to 380 mm. It is ideal for position detection in machinery requiring extended sensing reach. The unit features screw terminals and a G½ conduit entry, with pretravel rated at 15±5°, providing smooth mechanical operation and easy wiring access.
This model is built to withstand harsh environments, offering high shock resistance (1,000 m/s²) and vibration durability (10 to 55 Hz, 1.5 mm double amplitude). It operates in a wide temperature range from –10°C to 80°C and up to 95% relative humidity. With a minimum insulation resistance of 100 MΩ (at 500 VDC) and low initial contact resistance (25 mΩ), it ensures reliable switching performance. Designed without an indicator, the WLCAL4-N is suited for robust industrial applications requiring dependable actuation and long-term durability under IP67 protection.
