The Omron ZC-W155 Limit Switch uses a stainless-steel hinge lever with an SPDT contact form and is classified for general load. Frequency is specified 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 listed. The operating temperature range is -10 to 80°C, with relative humidity from 35 to 95%. Pollution degree 3 is specified according to IEC947-5-1, providing the main supporting environmental standard for this ZC-55 Series model.
Destructive shock resistance is listed at 1,000 m/s². The supplied row does not state a malfunction shock value, separate current or voltage rating, operating speed, operation frequency, connection type, or operation mechanism, so those details are not inferred from other ZC-55 products. The strongest exact-model terms are ZC-55 Series, stainless-steel hinge lever, SPDT contact form, general-load classification, 15 mΩ contact resistance, 100 MΩ insulation resistance, IP67 protection, 500,000 electrical operations minimum, and ten million mechanical operations minimum. This combination provides the technical identity of ZC-W155 while avoiding claims not present in the structured data. For another ZC-55 Series hinge-lever product page, see ZC-W55.
