What is a DB9 connector?

The term “DB9” refers to a common connector type, one of the D-Subminiature or D-Sub types of connectors. DB9 has the smallest “footprint” of the D-Subminiature connectors and houses 9 pins (for the male connector) or 9 holes (for the female connector).

Are DB9 and VGA the same?

The VGA connector can use a classic DB9 connector or (more commonly today) a DB15 style connector. … The VGA connector (15 pins) is still widely used and while it was originally used to carry a 640 x 480-pixel format it is used to carry a variety of geometries including HDTV formats. VGA is an analogue standard.

A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, ensures correct orientation, and may screen against electromagnetic interference. D-sub connectors have gender: parts with pin contacts are called male connectors or plugs, while those with socket contacts are called female connectors or sockets. The socket’s shield fits tightly inside the plug’s shield. Panel mounted connectors usually have 4-40 jackscrews that accept screws on the cable end connector cover that are used for locking the connectors together and offering mechanical strain relief. Occasionally the nuts may be found on a cable end connector if it is expected to connect to another cable end (see the male DE-9 pictured). When screened cables are used, the shields are connected to the overall screens of the cables. This creates an electrically continuous screen covering the whole cable and connector system.

The D-sub series of connectors was introduced by Cannon in 1952. Cannon’s part-numbering system uses D as the prefix for the whole series, followed by one of A, B, C, D, or E denoting the shell size, followed by the number of pins or sockets, followed by either P (plug or pins) or S (socket) denoting the gender of the part. Each shell size usually corresponds to a certain number of pins or sockets: 15, 25, 37, 50, and with 9. For example, DB-25 denotes a D-sub with a 25-position shell size and a 25-position contact configuration. The contacts in each row of these connectors are spaced 326/3000 of an inch apart, or approximately 0.1087 inches (2.76 mm), and the rows are spaced 0.112 inches (2.84 mm) apart; the pins in the two rows are offset by half the distance between adjacent contacts in a row. This spacing is called normal density. The suffixes M and F (for male and female) are sometimes used instead of the original P and S for plug and socket.
