Semi-Compact Sealed Switch [D4MC]
Caution
Product Description
Low-cost and highly practical enclosed switch
[Features]
· Enclosed switch with high durability of 10 million times or more and high repeatability due to built-in micro switch.
· Operation position of the panel mounting type is same as that of the Z type.
· Can be used in applications that require more strength, dust-proof properties and drip-proof properties than micro switches.
· Resin hardened mold terminals are also available.
· UL and CCC standard certified
Dimensional Drawing of OMRON Limit Switch
Note 1. In the above outer dimension diagrams for each model, the dimensional tolerance of parts not specified is ±0.4 mm.
Note 2. The operating characteristics are values measured when operated from direction A.
Note 3. Please limit OT so that it does not exceed the standard value of Limit Switch.

Limit Switch Structure
The cable can be pulled out from either the left or right side by replacing the terminal protection cover.
The terminal screws are M4 bind head screws (with internal tooth washers).
