The Omron ZC-W2155 Limit Switch uses a hinge roller lever with a 12.7 mm dia. × 7.5 mm stainless-steel lever and stainless-steel roller. It has 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.
Destructive shock resistance is listed at 1,000 m/s². The source does not provide a malfunction shock value, normal current rating, operating speed, operation frequency, connection type, or operation mechanism for this row, so those details are not inferred from other ZC-55 models. The strongest exact-model terms are ZC-55 Series, hinge roller lever, 12.7 × 7.5 mm stainless-steel lever and roller, SPDT contacts, general-load classification, IP67 protection, 15 mΩ contact resistance, 100 MΩ insulation resistance, and the stated durability figures. These specifications keep the page centred on ZC-W2155 without adding unsupported application or load claims. For another ZC-55 Series hinge-lever model, see ZC-W155.
