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” (+/- alternating display) or “-MP” (-/+ alternating display) after the “206” or “207” in the model number
(e.g., A7BS-206-PM, A7BS-207-PM-1, or A7BS-206-MP). There is no “-MP” type available, however, for A7BS-20@-S models.
*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).
*3. Models with diodes are available. Add “-D” to the model number (e.g., A7BS-207-D or A7BS-207-D-1).

End Caps
Spacers
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 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.

Stopper Pins
• Use A7BS-S Stopper Pins to make dial display restrictions for these Switches.
• Insert the Stopper Pins in the positions required to give the desired display range. For
example, for a display range of 0 to 5, insert a Stopper Pin at position 1 (see following
diagram) to stop the display from going above 5 when the (+) button is pressed, and insert
a Stopper Pin at position 2 to stop the display from going below 0 when the (-) button is
pressed.

A7BS/A7BL
Output Codes/Terminals
• Switches with output codes 06 or 07 both use binary coded decimal
but Switches with output code 07 have a component-adding
provision. Similarly, Switches with output codes 54 or 55 both use
binary coded hexadecimal but Switches with output code 55 have
a component-adding provision.
• How to Read Output Codes
For example, when the dial position is “3,” the common terminal C
on the Switch is connected to terminals 1 and 2. When the Switch
is inserted into the Connector, the common terminal C becomes
connector terminal 2, and terminals 1 and 2 become connector
terminals 4 and 5 respectively.

Safety Precautions
Refer to Precautions for Correct Use on page in the Technical Guide for Thumbwheel Switches.
Precautions for Correct Use
Handling
Models with External Stoppers (A7BS-20@-S)
• The molded components of the Switch use polyacetal resin and
ABS resin. It is recommended that alcohol is used to wipe off dirt
and smudges from the molded components. Take care to prevent
the alcohol from getting inside.
• A7BS/A7BL Thumbwheel Switches are not drip-proof. Do not use
them in areas subject to water or oil.
With the A7BS-20@-S, any range can be set externally using the
Stopper Pin. Insert the Stopper Pin using the following procedure:
(2) Stopper Pin (lower limit)
(3) Stopper Pin (upper limit)
• Do not allow solder flux or alcohol to enter the Switch.

Setting Numbers
Locking Type
Example: To Display the Range 0 to 7
1. Any number within the range of (0 to 7) can be chosen to limit the
numbers displayed in the display window. (In this example, 8 and
9 are outside of this range.)
2. First, insert the Stopper Pin in the hole

number to be defined.
• Return the button to its original position after setting. It is then
locked to prevent rotation, and the set numbers will not change
accidentally.
3. Next, inset the Stopper Pin in the hole
past the upper limit (“7”) for the number
to be defined. (The Stopper Pins then
surround the exact range to be
defined.)
4. Confirm that the (+) push-button can no
longer be pushed after reaching the
upper limit of (“7”).
5. Confirm that the (-) push-button can no longer be pushed after
reaching the lower limit of (“0”). This completes the setting.
