D-Sub, D-Shaped Connectors - Adapters

D-Sub connectors are cased plugs and sockets designed to terminate individual electrical conductors, making a secure, reliable connection. The 212563-1 is a standard D-Subminiature Connector/Adapter, with a square flange, 2 rows of 9 pins or 9 sockets, and an outer shell made of high-quality plastic. This D-Sub connector is a popular choice for control enclosures, office equipment, and assembly areas.

In terms of application fields, the 212563-1 D-Sub connector is broadly used in telecommunications, automotive, medical, and other areas needing point-to-point electrical connections. Generally, a plug is mated with its corresponding female socket, with a reliable secure fit, for connecting two sets of wires/cables. This design is effective in protecting the cables from corrosion, vibration, and loosening due to operation or temperatures, all while providing a secure connection. In addition, a variety of accessories and gadgets are available to help connect wires and pin sets when the standard D-Sub connector and socket are used.

In terms of working principles, the 212563-1 D-Sub Connector/Adapter is designed to terminate a single electrical conductor, and form a secure connection to the device or assembly. The plug features a high contact force to ensure good contact compression and maintains reliable connections. The pins are also designed to be low profile, to reduce the contact area with the mating conductors, and increase the signal transmission speed. The spring-type design of the pins and sockets helps to absorb dynamic energy and reduce shock and vibration.

The D-Sub also features a hermaphroditic design, which means the socket and the plug perform the same purpose and can be viewed as a “male” or “female” connector. This simplifies construction and allows the housing to feature a consistent diameter for the two parts.
