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).
