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.

Classification Screw mounting (back mounting) Snap-in (front mounting)
Accessory Color Light gray Black Light gray Black
End Caps (1 pair) A7D-1M A7D-1M-1 A7D-2M A7D-2M-1
Spacer A7D-1P[] * A7D-1P[]-1 * A7D-2P[] * A7D-2P[]-1 *

* 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.)

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.
