Product details
| ■ Switch (single switch section) |
| model | A7MD/A7MD-□-D | |
| classification(SEE NOTE1.) | Installed through printed circuit board | |
| character height | 2.8mm | |
| terminal | PCB terminals | |
| Output code number | colour | black |
| 06(Binary encoded decimal system) | A7MD-106-P-09 | |
| A7MD-106-P-09-D ＊ | ||
| Note 1. The classification diagram combines the four switch sections of the end cap to create a 4-digit display. 2. The model given above is for the 1 switch section. *Equipped with built-in diodes. |
| ■ Accessories (sold separately) |
| Use accessories such as end caps and partitions for the switch section. |
| classification | A7MD/A7MD-□-D |
| Attachment color | black |
| end cap | A7MD-1M |
| pad | A7MD-P□ |
| Note: The □ in the partition model represents the letters in the range A to U. (See the table in the partition description below.) |
| ■ End cap |
| End caps are used at each end of the switch section and allow all switch sections to be safely installed on the panel. They are provided in pairs, one on the left and one on the right. |
| ■ Partition board |
| The partition is used to create additional space or spacing between the switch sections, and is the same size as the switch sections themselves. There are also partitions with engraved characters or symbols that can be used to indicate units such as time and length. (Please refer to the table below.) Please consult your Omron representative office for details. |
