Enclosed Switch ZC- 55 Small, High-precision Enclosed Switch Small, High-precision Enclosed Switches with Built-in Basic Switches for High Repeatability and Durability of 10 Million Operations Minimum. Same mounting pitch as Z Basic Switch. Requires less operating force than conventional limit switches. Lineup includes modes with operation indicators for easy maintenance and inspection. Approved by EN, UL, CSA, and CCC (Chinese standard). (Ask your OMRON representative for Information on approved models.) Be sure to read Safety Precautions on page 7 and Safety Precautions for All Limit Switches.
