Introduction to D-Sub Connectors

A D-Sub connector, also known as a DE-9 connector, is a type of connector used primarily in computer and audio/visual applications. It is named after its distinctive D-shape, which is derived from the shape of the pins used for connection.

D-Sub connectors, or DE-9s, are commonly used for parallel and serial data connections in personal computers. They are also used for analog audio connections such as left/right stereo jacks on computers and devices, as well as for digital video connections. In addition, these connectors are often used for networking, serial devices, and other electronic equipment.
