Thumbwheel Switch A7CN/A7CN-L CSM A7CN/A7CN-L DS E 4 1 A Brand New Lineup of A7C Series Compact Thumbwheel Switches The series includes a complete range of locking-type models that prevent accidental operation. Ordering Information Switches (Single Switch Units) Model A7CN Screw mounting (back mounting) Snap-in (front mounting) Classification (See note 1.) Character height 3.4 mm Terminals PCB terminals Output code number Color Light gray Black Light gray Black 06 (binary coded decimal) --- A7CN-106-1 A7CN-206 A7CN-206-1 Model A7CN-L Snap-in (front mounting) Classification (See note 1.) Locking type Character height 3.4 mm Terminals PCB terminals Output code number Color Light gray Black 06 (binary coded decimal) A7CN-L206 A7CN-L206-1 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 in the model number (e.g., A7CN-206-PM or A7CN-206-PM-1). Accessories (Order Separately) Use accessories, such as End Caps and Spacers, with the Switch Units. Screw mounting Classification Snap-in (front mounting) (back mounting) Accessory Color Black Light gray Black End Caps (1 pair) A7CN-1M-1 A7CN-2M A7CN-2M-1 Spacer A7CN-1P -1 (See note.) A7CN-2P (See note.) A7CN-2P -1 (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.) 1A7CN/A7CN-L 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.)
