DB9 pin D sub connector Female connector:
DB9 pin D sub connector/dsub connector/.DE 9 or DB9 female Solder Type Connector In assembly of a working cable, is essential to provide the actual connection interface between two devices.The D-subminiature or D-sub is a common type of electrical . They are named for their characteristic D-shaped metal shield. Connector usually contains two or more parallel rows of pins or sockets surrounded by a D-shaped metal shield that provides mechanical support, ensures correct orientation, and screen against electromagnetic interference.
The DB9 (originally named DE-9) is an analog socket, dsub connector,from the D-Subminiatures (D-Sub) family. The DB9 has the smallest “footprint” of the D-Subminiature connectors. The prefix “D” represents the D-shape of the connector shell. The DB9 connector is mainly used in serial ports, allowing asynchronous data transmission according to the RS-232 standard (RS-232C). Note that there are DB9-DB25 adapters that easily convert a DB9 socket to DB25 and vice versa.
