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 1 Switch Unit.

3.Models with stoppers are also available. Add “-S @@” after the “203,” “206,” “207,” “219,” “254,” or “255” 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., A7PS-206-S06-1).

4.Models with +, - displays can also be produced. Add “-PM” after the “206” in the model number (e.g., A7PS-206-PM or A7PS-206-PM-1)*1.Models with PCB terminals are available.

*2.Models with diodes are available. Add “-D” to the model number (e.g., A7PS-207-D or A7PS-207-D-1).

Accessories (Order Separately)

Use accessories, such as End Caps and Spacers, with the Switch Units.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 that can be used for indicating units, such as time and length. (Refer to the following table.) Consult your OMRON representative for details.Model

Output Codes/Terminals

?Switches with output codes 06 or 07 both use binary coded decimal but Switches with output code 07 have a component-adding provision. Similarly, Switches with output codes 54 or 55 both use binary coded hexadecimal but Switches with output code 55 have a component-adding provision.

?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 3, and terminals 1 and 2 become connector

terminals 5 and 7 respectively.

Ordering Procedure

Place orders as shown in the example below, specifying the model and number.

Safety Precautions

Refer to Precautions for Correct Use on in the Technical Guide for Thumbwheel Switches .

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.

?A7P Thumbwheel Switches are dust-proof, but they are not drip-proof. Do not use them in areas subject to water or oil exposure.?Do not allow solder flux or alcohol to enter the Switch.

?Do not push the (+) and (-) operating push-buttons at the same time.
