CSM_A7BS/A7BL_DS_E_6_2

Thumbwheel Switch

A7BS/A7BL

Wide Range of Locking-type

Models Available

• Character height of 4.8 or 3.2 mm makes for easy-to-

view display.

• Installation is easy with snap-in mounting.

• The series includes a complete range of locking-type

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 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

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.)

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.

Thumbwheel Switches with External Stoppers:

A7BS-20@-S(-1)

• 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.

Refer to page 7 for details.

Stopper Pins

Note: 1. Two pins constitute one set.

2. The first shipment is free and is attached

to the Switch.

Order the A7BS-S separately if it is

required for maintenance.
