The Omron WLD18-N is a durable two-circuit limit switch built for demanding industrial environments. It features a sealed top plunger actuator for precise linear detection and supports screw terminal connections with a G½ conduit entry. With a pretravel of 1.7 mm max, the switch offers consistent and accurate actuation in compact setups.
This model is designed without an operation indicator and supports AC-rated operation at 50/60 Hz. It provides reliable insulation (100 MΩ min. at 500 VDC) and low contact resistance (25 mΩ max.). Operating reliably from –10°C to +80°C and 35–95% humidity, the WLD18-N is suitable for machines exposed to vibration and shock, withstanding up to 1,000 m/s² (destruction) and 300 m/s² (malfunction).
The WLD18-N is ideal for position detection in mechanical systems where ruggedness and sealing are critical. Its fully enclosed structure meets the requirements of IP67 protection.
