D-shaped (D-sub) connectors are a type of electrical connection used in a variety of applications, including computers, instrumentation, automotive, telecommunications, and other equipment. D-sub connectors consist of two halves, each with metal contacts. When mated, the contacts make an electrical connection. Some D-sub connectors are fitted with polarising keys to ensure the two sides of the connector only fit together one way. D-sub connectors are available in 9 to 50 positions and can also be used in serial data transfer applications.

D-sub connectors are available in two types: shielded and unshielded. Shielded D-sub connectors contain a metal shield between the contact and the mating surface which helps reduce interference. Unshielded D-sub connectors are exposed and can be easier to damage or cause interference. The choice of connector type depends on the application and expected environment.

The working principle of a D-sub connector is relatively simple. When two halves of a D-sub connector are mated, electrical connections are made between corresponding contacts on each side. The pins make contact with the mating surface of the other half at a pressure that has been defined for the specific connector. This ensures a reliable and secure connection between the two sides.

D-sub connectors are typically used in computers and other electrical equipment, instrumentation, and telecommunication applications. They are most commonly found on the back of computers and peripheral devices, such as keyboards and mice. D-sub connectors can also be used in serial data transfer applications, such as Ethernet networks and USB connections, where their design makes them suitable for use in even the most demanding environments.

To ensure reliable and secure connections, it is important to use the right type of D-sub connector for the application. The industry standard for connector performance is set out by the DE-15 standard (a variation of the D-sub connector). DE-15 connectors are available in both shielded and unshielded configurations. Both types of connectors must meet the DE-15 specifications in order to be used in applications that require this level of performance.

D-sub connectors are a reliable and secure way of making electrical connections. By choosing the right type of connector for the application, the connections made using D-sub connectors can provide a reliable data transfer rate and maintain a clean and reliable signal. D-sub connectors are an economical and efficient way of making connections in a wide range of applications.
