The Omron ZC-W255 Limit Switch uses a short hinge roller lever actuator specified with a 12.7 mm × 7.5 mm stainless-steel lever and stainless-steel roller. Its contact form is SPDT, the load category is general load, and the listed frequency is 50/60 Hz. Contact resistance is 15 mΩ max., while insulation resistance is 100 MΩ min. at 500 VDC. Electrical durability is 500,000 operations min. and mechanical durability is 10 million operations min. These values identify the ZC-W255 through its roller-lever construction, SPDT contact arrangement, general-load classification, resistance values, and durability figures. The general-load label is retained exactly as listed here. The actuator materials and dimensions are stated separately from the electrical characteristics, so the stainless-steel lever and roller should be treated as mechanical attributes of this configuration rather than inferred electrical features.
The ZC-W255 is rated IP67 and is specified for operation from -10 to 80°C with 35 to 95% RH. Pollution degree is listed as 3 according to IEC947-5-1, and the destruction shock value is 1,000 m/s². These environmental and mechanical values complement the contact, durability, insulation, and actuator data supplied for the model. Within the same ZC-55 product family, another direct product page is the ZC-W55.
