D-type connectors most commonly consist of two and sometimes more parallel rows of connections. The connectors have a D-format metal shell that provides mechanical strength and limited screening - the metal shells of the plug and socket make contact to provide screening. Panel mounting connectors are typically secured to the panel using nuts that have an additional thread allowing the mating connector to be secured to prevent working loose. Free connectors can have backshells that provide screening and can be connected to the cable screen, or if plastic, provide protection. Strain relief on the cable is also provided.

The pins in the more common connector types with two rows of pins (9, 15, 25 and 37 way) are spaced approximately 0.108 inch (2.74 mm) apart with the rows spaced 0.112 inch (2.84 mm) apart. High pin counts and higher pin densities can be achieved using more rows of pins.

• The D-type connector has been used in many applications as a multi-way connector, but it is probably most widely known as the connector used for RS-232 serial links
• The D-type connector was used for the serial link on most computers for many years, and today variations of D-type connectors are still found on most computers
• D-sub or D-subminiature connectors are common types of electrical components typically used in computing to help form connections on a circuit board
