Omron SHL-W355 Limit Switch
Omron SHL-W355 uses a unidirectional short hinge roller lever with a 9.5 mm × 4.0 mm stainless-steel roller and SPDT contacts for general-load switching. The source specifies IP67 protection, 15 mΩ maximum contact resistance, and 100 MΩ minimum insulation resistance at 500 VDC. Operating temperature ranges from -10 to 80°C with 35 to 95% relative humidity. The SHL-W355 is part of the SHL Series within the stainless roller lever switch range from Omron switching products. Its unidirectional short hinge roller lever is the main actuator-specific feature.

The Omron SHL-W355 Limit Switch uses a unidirectional short hinge roller lever fitted with a 9.5 mm diameter × 4.0 mm stainless-steel roller. Its SPDT contacts are classified for general load, with 50/60 Hz operation. IP67 protection and 15 mΩ maximum contact resistance are listed, while insulation resistance is 100 MΩ minimum at 500 VDC. Operating temperature ranges from -10 to 80°C with relative humidity between 35 and 95%. Pollution degree 3 is specified according to EN60947-5-1, adding another source-listed environmental classification.
Electrical durability is 500,000 operations minimum and mechanical durability is ten million operations minimum. The listed shock values are 1,000 m/s² for destruction and 300 m/s² for malfunction. No specific current or voltage load value is supplied in this row, so the general-load designation is retained without adding a rating from another SHL model. Its stainless-steel roller differentiates it from the plain short-hinge-lever version. For that related configuration, see the SHL-W55.
