Thumbwheel Switch

A7D/A7DP

Ultra-small, Low-cost, Push-operated

Switches

• All-in-one design means fewer parts are required. This product

delivers high reliability at a low cost.

• Uses long-lasting resin springs to achieve a long mechanical

durability expectancy of 30,000 operations.

• Models with stoppers for restricting the setting range are available.

• The series includes a complete range of pen-push models that

prevent accidental operation.

Ordering Information

Switches (Single Switch Units)

Note: 1. The classification diagrams show 4 Switch Units combined with End Caps to create 4-digit displays.

2. The model numbers given above are for 1 Switch Unit.

3. Models with stoppers are also available. Add “-S

@@” after the “106” or “206” in the model number and specify the display range in the @@. For example, to

specify the range 0 to 6, add “-S06” to the model number (e.g., A7D-106-S06-1).

4. Models with +, - displays are also available. Add “-PM” after the “106” or “206” in the model number (e.g., A7D-106-PM or A7D-106-PM-1).

Accessories (Order Separately)

Use accessories, such as End Caps and Spacers, with the Switch Units.

Note: The

@ in the Spacer model number stands for a letter in the range A to U. (Refer to the table in the following explanation about Spacers.)

* The minimum order is for 10 End Caps.

End Caps

End Caps are used on the Switch Units at each end and allow all the Switch Units to be securely mounted to a panel. They come in pairs, one for

the left and one for the right.

Spacers

• Spacers are used for creating extra space or gaps between the Switch Units and have the same dimensions as the Switch Units themselves.

• There are also Spacers with engraved characters or symbols that can be used for indicating units, such as time and length. (Refer to the following

table.) Consult your OMRON representative for details.
