Omron WLSD-N Limit Switch
Omron WLSD-N is a WL Series limit switch with a horizontal plunger, screw terminals, and a G½ conduit entry. The plunger has a maximum pretravel of 2.8 mm, and this model is specified without an operation indicator. IP67 protection, 100 MΩ minimum insulation resistance, and 25 mΩ maximum initial contact resistance are listed. Operating temperature ranges from -10 to 80°C with relative humidity between 35 and 95%. The WLSD-N belongs to the WL Series within the horizontal plunger limit switch range from Omron control components. Horizontal actuation and the absence of an indicator identify this version.

The Omron WLSD-N Limit Switch uses a horizontal plunger actuator with screw terminals and a G½ conduit connection. Maximum pretravel is specified at 2.8 mm, while the model is listed without an operation indicator. IP67 protection, 100 MΩ minimum insulation resistance at 500 VDC, and 25 mΩ maximum initial contact resistance are included in the structured specifications. Operating temperature ranges from -10 to 80°C with relative humidity from 35 to 95%. The frequency value is listed at 50/60 Hz.
Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. The switch is specified for destructive shock of 1,000 m/s² minimum and malfunction shock of 300 m/s² minimum. The horizontal plunger and no-indicator construction are the main identifiers because the source does not provide a separate current or voltage load rating. For a horizontal-ball plunger model with the same 2.8 mm maximum pretravel but an LED operation indicator, see the WLSD3-LD-N.
