Omron WLD38-N Limit Switch
Omron WLD38-N is a WL Series limit switch with a sealed top-ball plunger, screw terminals, and a G½ conduit connection. The source specifies 1.7 mm maximum pretravel and identifies this version as having no operation indicator. IP67 protection, 100 MΩ minimum insulation resistance at 500 VDC, and 25 mΩ maximum initial contact resistance are listed. Operating temperature ranges from -10 to 80°C with relative humidity from 35 to 95%. The WLD38-N belongs to the WL Series within the sealed ball plunger limit switch range from Omron switching components. The sealed top-ball plunger is its primary actuator feature.

The Omron WLD38-N Limit Switch uses a sealed top-ball plunger with screw terminals and a G½ conduit connection. Maximum pretravel is specified at 1.7 mm, and this version has no operation indicator. The source lists IP67 protection, 100 MΩ minimum insulation resistance at 500 VDC, and 25 mΩ maximum initial contact resistance. Operating temperature extends from -10 to 80°C without icing, with relative humidity between 35 and 95%. Operation frequency is listed at 50/60 Hz.
Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. Shock resistance is specified at 1,000 m/s² minimum for destruction and 300 m/s² minimum for malfunction. No current or voltage load rating is supplied in this row, so those values are not borrowed from another WL model. The sealed top-ball plunger and 1.7 mm maximum pretravel are the most useful model-specific details. For a related horizontal-ball plunger model that includes LED indication, see the WLSD3-LD-N.
