The Types of D SUB Connectors (List)

 D-SUB connector cables are commonly used in computing, video, and communication applications. These connectors are also used in military, medical, industrial, data, instrumentation, and consumer applications. D-sub connectors are named for their unique D-shaped shield shape. This metal shield protects the connector's two or more rows of Pin pins or females, ensuring that the connector is mated for docking through proper orientation and alignment. It should fit snugly inside the shield of another male header. Sometimes the shield is also designed to prevent electromagnetic interference.

 

Types of D-sub Connectors

The pins of a D-sub connector are arranged in parallel rows (at least two and at most five). The space between the pins is called the density of the connector. The three densities of D-sub connectors are normal, high, and double.

Density	Row spacing	Pin spacing
Normal	2.84 mm (0.112 in)	2.76 mm (0.1087 in)
High	2.0 mm (0.078 in)	2.3 mm (0.090 in)
Double	Unspecified	Unspecified

 

Types of D-sub Connectors：

D-sub type	Pin layout	Density	Notes
DE-9	5–4	Normal	Commonly used for a computer's serial port. The DB-9 connector is sometimes used for token ring adapters. DB-15 connectors may also appear on tick coaxial cables.
DA-15	8–7	Normal	Used for VGA connections, 10BASE5 (thick Ethernet, or "thicknet"), serial ports, and some NICs (network interface cards).
DE-15	5–5–5	High
DB-19	10–9	Normal	Connection for monitors and disk drives, used on early Macintosh and NeXT computers. Also used for ASCI data connections on some Atari computers of that era.
DE-19	6–7–6	Double
DB-25	13–12	Normal	Used for parallel port connections.
DA-26	9–9–8	High
DA-31	10–11–10	Double
DC-37	19–18	Normal	Used on some Cisco, Nortel, SMC, et al., network appliances. Also used in various models of sensors, switches, satellite antennas, control systems, video hardware, security control systems, etc.
DB-44	15–15–14	High
DD-50	17–16–17	Normal	Legacy SCSI connections.
DB-52	17–18–17	Double
DC-62	21–21–20	High
DD-78	20–19–20–19	High
DC-79	26–27–26	Double
DD-100	26–25–24–25	Double
DF-104	21–21–21–21–20	High

 

PS：The number in the type name indicates the number of active wires in the connector, not necessarily the number of its pins.
