D-sub connectors are suitable for various electronic products. They often appear on communication ports and are used to connect different products such as computers, printers, and power supply units. DB9 connectors are used in token ring networks and other computer networks and controller area networks (CAN). D-sub connectors are also used for computer video output, game controller ports, multi-channel analog, and AES digital audio recording studios.
Over the years, the use of connectors has changed with the technology available at the time. For example, early Macintosh computers used D-sub to connect external floppy disks, and Commodore Amiga used D-sub to connect external floppy disks and video output. But due to their size and cost, the use of D-sub connectors in consumer products has almost disappeared. However, they are still popular in non-consumer applications because their combination of shape, size, density, and cost provide important value to end users.
