The Omron WLSD3-LD-N is a compact and reliable two-circuit limit switch designed for precision actuation in control panels and industrial machinery. It features a horizontal-ball plunger for smooth mechanical operation and uses screw terminals with a G½ conduit entry for secure wiring. The built-in LED indicator offers visual confirmation of switch activation, improving diagnostics and reducing downtime.
This model supports a minimum applicable load of 5 VDC at 1 mA (resistive), with leakage current of approx. 0.4 mA at 10 VAC/DC and 0.5 mA at 115 VAC/DC. It operates at frequencies up to 50/60 Hz and endures vibration (10–55 Hz, 1.5 mm double amplitude) and shock (up to 1,000 m/s²). The switch performs reliably in ambient temperatures from –10°C to +80°C and up to 95% relative humidity. The WLSD3-LD-N is housed in a durable enclosure with IP67 protection.
