Omron SHL-W2155-01 Limit Switch
Omron SHL-W2155-01 is an enclosed microload limit switch with a hinge roller lever, SPDT contacts, and a snap-action mechanism. It supports non-inductive loads of 0.1 A at 125 VAC and 0.1 A at 8, 14, or 30 VDC. IP67 protection, 15 mΩ maximum contact resistance, 100 MΩ minimum insulation resistance, and ten million minimum mechanical operations are specified. The SHL-W2155-01 belongs to the SHL Series within the hinge roller lever switch range from Omron limit switch products. Its roller lever distinguishes it from panel-plunger SHL models.

The Omron SHL-W2155-01 Limit Switch uses a hinge roller lever with SPDT contacts and a snap-action mechanism. It is identified as an enclosed microload switch and supports non-inductive loads of 0.1 A at 125 VAC as well as 0.1 A at 8, 14, and 30 VDC. The housing material is listed as zinc. IP67 protection, 15 mΩ maximum contact resistance, and 100 MΩ minimum insulation resistance at 500 VDC are specified. Operating temperature extends from -10 to 80°C with relative humidity between 35 and 95%.
Mechanical durability reaches ten million operations minimum and electrical durability reaches 500,000 operations minimum. Malfunction vibration resistance covers 10 to 55 Hz at 1.5 mm double amplitude. Destructive shock resistance is 1,000 m/s² maximum and malfunction shock resistance is 300 m/s² maximum. The hinge roller lever and defined AC/DC microload values make this model clearly different from SHL panel-plunger versions. For a related SHL microload model using a 7.8 mm panel-mount stainless-steel plunger, see the SHL-Q55-01 model.
