A DB25 connector is a commonly used connector port in computers. DB-25 stands for D-sub with a 25-bit case size and 25-bit contact configuration, and the ports of personal computers were the first to use DB-25 connectors.

The DB25 pin connector is an analog socket of the D-Subminiatures (D-Sub) connector family with 25 pins. The prefix "D" represents the D shape of the connector housing. The DB25 connector is mainly used for serial and parallel ports, allowing asynchronous data transfer according to the RS-232 standard (RS-232C).

According to the connection method, D-Sub connectors can be divided into the following three types:

1. DB25 DSUB connector with solder contacts.

2. 25 pin connector with insulation displacement contacts.

3. 25-pin D-type connector with crimp terminals.

There are also two types of PCB mount connectors, straight or right-angle termination styles. This type of 25-pin D-Sub connector has built-in solder tails for easy mounting on a PCB.

What is the purpose of the DB 25-pin connector?

Like the DB9 connector, the DB25 is primarily used for serial connections, allowing asynchronous transfer of data provided by standard RS-232 (RS-232C). It is also used for parallel port connections, originally for connecting printers, and is sometimes called a "printer port".
