The Omron ZC-W55 Limit Switch combines a short stainless-steel hinge lever with SPDT contacts for general load. It operates at 50/60 Hz and carries IP67 protection. Maximum contact resistance is specified at 15 mΩ, while insulation resistance is 100 MΩ minimum at 500 VDC. Its operating range is -10 to 80°C with relative humidity from 35 to 95%. Pollution degree 3 is listed according to IEC947-5-1. The source does not provide a specific current or voltage rating in this row, so the general-load classification is used without adding values from another model.
Electrical durability is specified at 500,000 operations minimum and mechanical durability at ten million operations minimum. Destruction shock is listed at 1,000 m/s²; no separate malfunction shock value is supplied for this model. Its short stainless-steel hinge lever closely parallels the SHL-W55 actuator description while the series designation differs. For the related SHL Series short-hinge-lever model, see the SHL-W55.
