D4MC

Note: 1. Unless otherwise specified, a tolerance of

±

0.4 mm applies to all dimensions.

2. Operating characteristics are for when the Switch is operated from direction A.
3. Make sure that the permissible OT position is not exceeded.

Molded Terminal Models (Not Approved by UL, CSA, or EN)

Use Switches with molded terminals in locations subject to dirt, dust, oil drops, 

or high humidity. Molded terminals are available with all D4MC models. 

Dimensions and operating characteristics are the same as the basic models.

Suffix by Location of Lead Outlet

Note: To form the model numbers for molded terminals models, add the 

numbers 1 to 3 in the table above to the end of the model number in 
Ordering Information on page 1.

Leads Supplied

Note: Add the VCT length to the end of the model number when ordering.

Consult with your OMRON representative for other types of lead wires 
and for lead wires longer than 3 m.
