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). 1 A7BS/A7BL Accessories (Order Separately) Use accessories, such as End Caps, Spacers, and Connectors with the Switch Units.

A7B-C A7B-CP 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 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.

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.

Similarly, Switches with output codes 54 or 55 both use binary coded hexadecimal but Switches with output code 55 have a component-adding provision. Output code number • 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.

Standard products are not factory-assembled for shipment. Contact your OMRON representative for details on ordering factory-assembled sets. 4 1. 2. 3. 4. 1 3 2 4 A7BS-206 (Switch Unit): 2 pieces A7BS-207 (Switch Unit): 2 pieces A7B-PA (Spacer): 1 piece A7B-M (End Caps): 1 pair Safety Precautions Refer to Precautions for Correct Use on page in the Technical Guide for Thumbwheel Switches. Precautions for Correct Use Handling • 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. • Do not allow solder flux or alcohol to enter the Switch. Models with External Stoppers (A7BS-20@-S) With the A7BS-20@-S, any range can be set externally using the Stopper Pin. Insert the Stopper Pin using the following procedure: (3) Stopper Pin (upper limit) (2) Stopper Pin (lower limit) (1) Display window Setting Numbers Locking Type • Set with the setting button by raising it. • Return the button to its original position after setting. It is then locked to prevent rotation, and the set numbers will not change accidentally. 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 in front of the lower limit (“0”) for the number to be defined. 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. 7 Read and Understand This Catalog Please read and understand this catalog before purchasing the products.
