A D-Sub cable, also known as a D-subminiature cable, is a type of cable that is commonly used to connect computer devices. They come in various configurations, ranging from 9 to 50 pins, and choose between low-density D-subs with two rows of pins/sockets or high-density D-subs with three rows.

The D-Sub cable is typically used for transmitting analog or digital signals, such as video, audio, or serial data, and between devices. They are commonly used to connect devices such as monitors, printers, modems, and other peripherals to a computer or other electronic devices. The D-Sub cables are also used in some industrial and military applications where robustness is needed.
