Introduction to D-Sub Connectors

A D-Sub Connector, or more commonly known as a connector with D-Subminiature design, is a type of electrical connector commonly used in computers and electronics. It has two or more parallel rows of pins or sockets surrounded by a D-shaped metal shield. The shield helps to protect against dust, dirt and other debris that could otherwise damage the contacts. D-Sub Connectors come in a variety of sizes and configurations. Common sizes include the DB9, DB15, and DB25. There are also several specialty types, including the E-Connector, which has seven pins arranged in a V-shaped pattern.
