The Omron WLNJ-30-N is a two-circuit limit switch designed for general-purpose detection in industrial environments. It features a 4.8 mm diameter coil spring actuator, providing flexible mechanical response in applications requiring extended reach or indirect actuation. The switch includes screw terminals with G½ conduit size and a pretravel of 20±10 mm for mechanical flexibility during setup.
Rated for 50/60 Hz operation, this model offers strong durability, high insulation resistance (100 MΩ at 500 VDC), and low contact resistance (25 mΩ max.). It performs reliably in temperatures from –10°C to +80°C and humidity up to 95%RH. Built to handle vibration (10–55 Hz, 1.5 mm double amplitude) and shock (up to 1,000 m/s²), the WLNJ-30-N is ideal for demanding automation and control systems. Its sealed housing ensures long-term operation even in dusty or wet environments, backed by IP67 protection.
