DB25 MaleConnector (Wire Type)

 

This is DB25Male type connector with facility to solder wires on inner side.

 

The DB25(originally DE-25) connector is an analog 25-pin plug of the D-Subminiatureconnector family (D-Sub or Sub-D).

 

As with theDB9 connector, the DB25 is mainly used for serial connections, allowing for theasynchronous transmission of data as provided by standard RS-232 (RS-232C).

 

It is alsoused for parallel port connections, and was originally used to connect printers,and as a result is sometimes known as a "printer port" (LPT forshort).

 

So to avoidconfusion, DB25 serial ports on computer generally have male connectors, whileparallel port connectors are DB25 female plugs.
