The Omron SHL-W155 Limit Switch uses a hinge roller lever with a 9.5 mm dia. × 4.0 mm stainless-steel roller and an SPDT contact form. It is classified for general load and operates at 50/60 Hz. Maximum contact resistance is 15 mΩ, while insulation resistance is 100 MΩ minimum at 500 VDC. Electrical durability is 500,000 operations minimum and mechanical durability is ten million operations minimum. IP67 protection is specified. The operating temperature range is -10 to 80°C, with relative humidity from 35 to 95%. Pollution degree 3 is listed according to EN60947-5-1.
Destructive shock resistance is listed at 1,000 m/s² and malfunction shock resistance at 300 m/s². The source does not attach max. or min. wording to these two shock values, so none is added. The strongest exact-model terms are SHL Series, hinge roller lever, 9.5 × 4.0 mm stainless-steel roller, SPDT contacts, general-load classification, 15 mΩ contact resistance, 100 MΩ insulation resistance, IP67 protection, and the stated durability values. No current rating, operating speed, operation frequency, connection type, or actuator direction is supplied in the structured row. These omitted values are not inferred from neighboring SHL products. For another SHL Series roller-lever model with a specified stainless-steel roller, see SHL-W355.
