The Omron WLD38-N is a compact, high-reliability two-circuit limit switch equipped with a sealed top-ball plunger actuator for precise mechanical detection. It features screw terminals for secure wiring and supports conduit connection via GΒ½ threads. With a pretravel of 1.7 mm max, it offers accurate and repeatable operation for position sensing in automation systems.
The switch operates at standard 50/60 Hz and performs reliably under harsh conditions. It withstands vibrations (10β55 Hz, 1.5 mm double amplitude) and shock up to 1,000 m/sΒ² (destruction). Electrical performance includes insulation resistance β₯100 MΞ© (500 VDC), contact resistance β€25 mΞ©, and a wide operating temperature range from β10Β°C to +80Β°C.
Built for long-term durability in tough environments, the WLD38-N is commonly used in machinery, conveyors, and safety mechanisms. Its fully enclosed structure ensures dust and water resistance with dependable IP67 protection.
