D-sub or D-shaped connectors are a type of electrical connector widely used for connecting digital communications, computer systems, and peripherals. They feature a small flat area surrounded by a larger recess, which helps to provide a high degree of shielding from electromagnetic interference and crosstalk. The two most commonly used housing types are the 9-pin (163X10169X) and 25-pin (DB25) housings. Each of these housings have a corresponding gender, with a female housing type being the 9-pin, designated by the letter F, and the 25-pin housing designated by the letter M.

The 163X10169X applications are predominantly used in the RS-232 serial cable. Known formally as the DE-9 connector, it is also called a "PC serial port," as this was the type of connector used on early IBM-PC computers. It is used for connecting digital communications, computer systems, and peripherals. This type of connector is commonly used to link serial electronic devices, such as computer monitors and modems. It is also used in point-of-sale devices, networking components, and process control systems.

The 9-pin housing is unique in the fact that it has two rows of four pins, with the smaller row in the center. This allows for the use of the DE-9 connectors to support both the RS-232 serial cable as well as the RS-485 cable. RS-485 cable requires a break in the middle pins to be able to reliably transmit data over a two-wire connection. The DE-9 connector also supports the optional use of a special 9-wire cable that includes two conductors for the break.

The working principle of the D-sub connectors is quite straightforward: pins along the housing are connected to the other half via contact pins. The housing is then secured with screws or pins, depending on the type of connector. This allows for a connection that is reliable and secure, as the contacts are not exposed to wear and tear.

The D-sub connectors are designed with a “U” shaped notch in the housing. This U-shaped notch is designed to provide support and ensure that the female side sits firmly against the male side and can withstand considerable force from the connection. This technique also ensures proper shielding of the connection from electromagnetic interference and crosstalk.

The D-sub connectors are available in a variety of sizes and configurations, allowing them to be used in a wide range of applications. The 163X10169X connector is a popular choice for connecting digital communications, computer systems, and peripherals. It is also often used in point-of-sale devices, networking components, and process control systems. D-sub connectors are an essential component for any application that requires a reliable and secure data connection.
