Enclosed Switch

D4MC

Economical, High Utility Enclosed Switch

Enclosed Switches with Built-in Basic Switches for High 

Repeatability and Durability of 10 Million Operations Minimum.

Panel mount versions have the same operating position as 

Z Basic Switch.

Suitable for applications demanding higher mechanical 

strength, dustproof and drip-proof properties than those 

on basic switches.

Resin molded terminal versions are available.

Approved by UL, CSA, and CCC (Chinese standard).

(Ask your OMRON representative for information on 

approved models.)

Be sure to read 

Safety Precautions

 on page 5 and

Safety Precautions for All Limit Switches
