The Omron WLCA32-43LD-N is a compact, high-precision two-circuit limit switch designed for microload applications. It features a fork lock lever actuator and screw terminal connection (G½ conduit size), offering easy installation in control systems. The switch includes an LED operation indicator, enhancing visibility during setup or troubleshooting. It supports minimum loads down to 5 VDC, 1 mA (resistive), with leakage current as low as 0.4 mA at 10 V and 0.5 mA at 115 V.
Built-in components ensure reliable performance with 100 MΩ insulation resistance and low 25 mΩ contact resistance. It withstands mechanical shock up to 1,000 m/s² and vibration from 10 to 55 Hz. The unit operates in environments from –10°C to 80°C and 35–95% humidity. The WLCA32-43LD-N is ideal for use in factory automation, positioning detection, and safety applications requiring compact form, signal clarity, and IP67 protection.
