The Omron WLCAL4-LD-N is a precision two-circuit limit switch equipped with a long adjustable rod lever (350 to 380 mm) for flexible detection across wide ranges. Designed with screw terminals and a conduit size of G½, it simplifies field wiring in rugged industrial setups. This model includes an LED operation indicator for visual feedback and supports a minimum load of 1 mA at 5 VDC (P-level), ensuring reliable microload switching.
The switch supports both AC and DC operation between 10 and 115 VAC/DC, with leakage current as low as 0.4 mA. Built for long service life, it offers high insulation resistance (100 MΩ) and low contact resistance (25 mΩ max). Operating temperatures range from –10°C to 80°C with up to 95% humidity. It withstands vibrations (10–55 Hz) and shocks (up to 1,000 m/s²), making the WLCAL4-LD-N ideal for demanding environments requiring long-reach sensing and IP67 protection.
