D-Sub Connectors

D-sub connectors, also known as 09652625812, are an industrially used electrical interface. They serve to connect computers and their related peripherals, as well as industrial and automated equipment. The D-sub is so named because of its similarity in shape to the letter "D".

Application Fields

D-sub connectors are used in various settings and for a wide range of functions. Most commonly, these connectors are used in personal computers and computer-related hardware and peripherals. Examples include keyboards, mice, modems, printers, and digital video displays. In industrial settings, D-sub connectors are commonly used in automated testing assemblies and various instrumentation applications.

Construction and Design

The physical design of D-sub connectors includes multiple rows of pins that are mounted on a metal or plastic housing. Connectors may vary in pin or contact count and are typically available in two, three, four, and nine-row designs. All designs of contacts are held securely in place in recessed cavities and are prevented from dislodging by means of mounting screws.

Cable and Accessory Options

Like most other types of connectors, D-sub connectors may come with a variety of mating cables and accessories. This typically includes jacks, a range of cable types, contacts, crimp and IDC assemblies, backshells, cable clamps, strain reliefs, and pressure caps. D-sub accessories are available in various finishes and metals including nickel tin, zinc, and stainless steel.

Working Principles

D-sub connectors use a combination of metal contact pins and sockets to create electrical connections. As cables are mated to the connectors, metal contact pins on the plug insert into sockets in the receptacle. This creates a secure connection point for various high-frequency signals to be transmitted between two devices. To disconnect the connection, users can simply pull the cables from the male and female interfaces.
