D-Sub Connectors

The D-sub connector, also known as D-subminiature, is a type of electrical plug used for connecting PC-related equipment. This type of connector is commonly used in the video, audio, and communications industries. The D-sub connectors are classified based on the number of contacts they have. There are three main categories in the D-sub family: D, DD, and DDX. Within those three categories, each connector can have either solder, horizontal, or vertical contact arrangements.
