Note 1. The classification chart displays four bodies combined with the top cover to create a 4-digit display.
2. The models given above are for the main body.
3. Models with+and - displays can also be made.
Add "- PM" (+/- alternate display) or "- MP" (-/+alternate display) after "206" or "207" in the model
(For example, A7BS-206-PM, A7BS-207-PM-1, or A7BS-206-MP).
But for the A7BS-20 □ - S model, there is no available "- MP" type.
*For models with PCB terminals, add "- P2" to the model (e.g. A7BS-207-P2-1).
*2. Also provide models with internal stops. Add "- S □□" after "206" or "207" in the model and specify the display range in □□.
For example, to specify a range of 0 to 6, add "- S06" to the model number (e.g. A7BS-206-S06-1).
Due to structural reasons, models with internal stops cannot be made for A7BS-254 and A7BS-255.
*3. Provide models with diodes. Add '- D' to the model number (e.g. A7BS-207-D or A7BS-207-D-1).
| ■ Accessories (sold separately) |
Use accessories such as top covers, partitions, and connectors for the body.

Note: The □ in the partition model represents the letters in the range A to U. (See the table in the partition description below.)
| ■ Top cover |
The top cover is used at each end of the body and allows all bodies to be safely installed on the panel. They are provided in pairs, one on the left and one on the right.
| ■ Partition board |
The partition is used to create additional space or spacing between the bodies, and is the same size as the body itself. There are also partitions with engraved characters or symbols that can be used to indicate units such as time and length. (Please refer to the table below.) Please consult your Omron representative office for details.

A7BS-2□□(-1) Welding terminals |
| Note 1. The above dimensions include two top covers and will add 8mm for each inserted partition. |
|
The unmarked tolerance in the external dimension drawings of the above models is ± 0.4mm. The tolerance for multiple connections is ± (number of units x 0.4) mm.
|
|
Dial switch with external stop: A7BS-20□-S(-1) |
| Use A7BS-S stop pins to limit the dial display of these switches. Insert the stop pin at the desired position to provide the desired display range. For example, for a display range of 0 to 5 Insert the stop pin at position 1 (as shown in the figure below) to prevent the display from rising above 5 when the (+) button is pressed Insert the stop pin at position 2 to prevent the display from dropping below 0 when the (-) button is pressed. |
|
*If the output code is 06, the size is 32.5; If the output code is 07, the size is 43.5.
