Introduction to D-Sub Connectors

D-sub connectors, or more commonly known as D-subminiature connectors, are a type of electrical connector that are commonly used in electronics and telecommunications applications. They have been around since the early 1950s and have become the most popular type of connector for use in data-critical applications. A D-Sub connector is made up of a female receptacle and a male contact, both of which are connected to a backshell – the metal body that holds the components of the connector together. This backshell can also be known as an insulator or a shell typically made up of aluminum, brass or plastic. The contacts can be made from gold, silver, nickel or copper, with the related mating hardware either constructed from the same or a different material. There are a variety of types of D-Sub connectors available on the market, with the common types being those with 9, 15, 25 and 37 pins.
