A D-sub connector, or D-subminiature connector, is a compact, pin-and-socket electrical/video connector that is specially designed for high-density packages. These devices are named for the D-shaped metal shield that surrounds and protects the pins and sockets; “subminiature” refers to the fact that D-sub connectors were some of the smallest computer connection components available when they were first introduced.
What Is A D-Subminiature Connector?
A typical D-sub connector consists of a male plug with two or more parallel rows of pins and/or sockets, which are surrounded by a capital D-shaped metal ring. In addition to protecting the delicate components, the D shield helps ensure correct orientation during installation and provides mechanical support; some D shields also provide EMI/RFI protection.
There are countless D-subminiature connector variations, with varying pin counts and configurations. Common D-sub connector options range from DE-9 (which has nine pins arranged in two rows) to the DD-50 (with 50 pins arranged in three rows). Hybrid styles may feature a combination of both standard pins and other connection components, such as coaxial connectors. For installation versatility, D-sub connectors are available in cable mount and board mount styles, among others.
