Ordering Information Switches (Single Switch Units) Model A7MD Mounts via printed circuit board Classification (See note 1.) Character height Terminals Color Output code number 06 (binary coded decimal) 2.8 mm PCB terminals Black A7MD-106-P-09 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. Accessories (Order Separately) Use accessories, such as End Caps and Spacers, with the Switch Units. Accessory End Caps Spacer Classification Color A7MD Black A7MD-1M A7MD-P@ 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.) 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.

Ordering Procedure • Standard products, such as the Switch Units and End Caps, are not factory-assembled for shipment. Safety Precautions Refer to Precautions for Correct Use on in the Technical Guide for Thumbwheel Switches. Precautions for Correct Use Handling • Do not drop the Switch. Doing so may possibly result in deformation of the terminals or damage to the PCB. • The molded components of the Switch use polyacetal resin and ABS resin. It is recommended that alcohol be used to wipe off dirt and smudges from the molded components. Take care to prevent the alcohol from getting inside. • Do not use them in areas subject to dust, water, or oil exposure, and do not operate with wet or oily hands. • Dust from the surrounding air may cause a faulty contact. Always check the Switch after setting it up to ensure that it is outputting correctly. • Tighten mounting screws to a torque between 0.2 to 0.24 N·m, using M2.6 screws. Use plain washers or spring washers together with the screws. • To separate the Switches, use a flat-blade screwdriver as shown in the following figure to release the hooks on the top and bottom and then separate the Switches. Be careful not to bend the hooks. 3 Terms and Conditions Agreement Read and understand this catalog. Please read and understand this catalog before purchasing the products.
