D-SUB Connector Introduction: What You Should Know About D-Sub Connectors!

The interface shape of D-SUB connectors resembles an uppercase “D,” which is why this type of connector is commonly referred to as D-SUB. These connectors are used for analog or digital interface signals and can be found in various applications in our daily lives, such as printer cables and monitor cables.

D-SUB connectors are available in different types, including DB solder-type, DBH plug-type, DML crimp-type, DMS straight-type, DMR right-angle board-mount type, DMRH right-angle board-mount type, 57S straight-type, 57BR right-angle board-mount type, DRB pin-type, HDC ultra-thin type. Additionally, there are DVI series, VGA series, DR series, HDR series, SCSI series, and high-current series connectors. Among these, the VGA series and DVI series are the most commonly used D-SUB connectors.

The connector housing of D-SUB connectors is available in five different sizes, and each housing size can have two different pin configurations. Standard housing sizes have 2 rows of pins, while high-density housing has 3 rows of pins.

D-SUB connectors are relatively large in size and can appear heavier compared to newer connectors. As a result, it can be challenging to connect and disconnect these connectors in tight spaces. However, right-angle adapters can rotate 90 degrees without damaging the connector, helping to effectively utilize D-SUB connectors in cramped spaces.

The pins inside the housing of D-SUB connectors are exposed, making them susceptible to bending or breaking. To prevent pin damage, it is recommended to use D-SUB plug or socket protective caps to safeguard the pins when not in use. Additionally, gender changers and socket savers can help reduce stress on the connectors caused by frequent plugging and unplugging.
