D-Sub, D-Shaped Connectors - Contacts 09691817230D-sub miniature connectors are an electrical connector. They are usually used to join two sections of electrical circuits. They are the most widely used connector type due to their robustness and versatility. Most often, they feature a D-shaped metal shell Designed to fit a variety of standard sized terminals, and may feature more than one row of pins or sockets depending on the purpose.The most common type of D-sub is a 9-pin. It is by far the most popular type for use in computers for connecting external peripherals such as printers, keyboards and mouse. The 9-pin has two rows of four pins, with one pin in the centre being electrically connected to the other pins or sockets, depending on its configuration.In more advanced applications, a 25-pin D-sub can be used. This type has two rows of nine pins, with two extra pins at the top and bottom for specific purposes. It is commonly used for RS232 serial connections, parallel communication and audio connections.Miniature D-sub connectors are also available, primarily used in the telecommunications industry. The contact arrangement is the same as for the standard sized connector; however, the smaller format allows multiple connections to be made in a compact form.The contacts within a D-Sub are usually made from either brass or stainless steel, depending on the application. contacts feature a springy action to ensure a secure contact is always made. Connectors also come with a variety of add-ons such as latching, lids or strain relief.In practical terms, D-Sub connectors offer a standardised connection for IT, networking and automotive devices. Although they may not be the most modern, most computers can benefit from them when it comes to connecting older equipment. More recently, USB A-type sockets are also becoming commonplace as they are much smaller, more robust and faster in use than D-Sub connectors.In conclusion, the D-Sub equipment is a reliable and popular connector type due to their size, ease-of-use and available variants. As such, they are a go-to choice for many devices, both old and new. They offer a reliable and versatile connection and a tried and tested solution for many applications.
