Thumbwheel Switch
A7D/A7DP
Ultra-small, Low-cost, Push-operated Switches
• All-in-one design means fewer parts are required. This product delivers high reliability at a low cost. • Uses long-lasting resin springs to achieve a long mechanical durability expectancy of 30,000 operations. • Models with stoppers for restricting the setting range are available. • The series includes a complete range of pen-push models that prevent accidental operation.

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 1 Switch Unit. 3. Models with stoppers are also available. Add “-S@@” after the “106” or “206” 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., A7D-106-S06-1). 4. Models with +, - displays are also available. Add “-PM” after the “106” or “206” in the model number (e.g., A7D-106-PM or A7D-106-PM-1).
Accessories (Order Separately)
Use accessories, such as End Caps and Spacers, with the Switch Units. Classification Accessory Color End Caps (1 pair) Spacer Screw mounting (back mounting) Light gray Black A7D-1M * A7D-1M-1 * A7D-1P@ A7D-1P@-1 (See note.) (See note.) Snap-in (front mounting) Light gray Black A7D-2M * A7D-2M-1 * A7D-2P@ A7D-2P@-1 (See note.) (See note.)
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.) * The minimum order is for 10 End Caps.
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 thatcan be used for indicating units, such as time andlength. (Refer to the following table.) Consult your OMRON representative for details. Symbol Stamp Symbol Stamp A No designation H cm B SEC J m C MIN K °C D H L PCS E g Q x 10 SEC F kg T 0 G mm U •
