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 Switch Units.
         3. Models with +, - displays can also be produced. Add “-PM” after the “206” or “207” in the model number
           (e.g., A7BS-206-PM or A7BS-207-PM-1).
*1. For models with PCB terminals, add “-P2” to the model number (e.g., A7BS-207-P2-1).
*2. Models with internal stoppers are also available. Add “-S[][]” after the “206” or “207” 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.,
       A7BS-206-S06-1).
       For structural reasons, models with stoppers cannot be manufactured for the A7BS-254 and A7BS-255.
*3. Models with diodes are available. Add “-D” to the model number (e.g., A7BS-207-D or A7BS-207-D-1).

Accessories (Order Separately)

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

End Caps, Spare Units, and Connectors

Accessory Color Light gray Black
End Caps (1 pair) A7B-M A7B-M-1
Spacer A7B-P[] * A7B-P[]-1 *
Connectors Solder terminals A7B-C
PCB terminals A7B-CP

* 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.
