D-Sub contacts, also known as D-shaped contacts, are connectors that are typically found on data cables and communication cables. They are shaped like the letter D, which makes them stand out from other connectors. The contacts are usually made of copper or brass and are designed to provide a secure connection. The contacts are usually surrounded by insulation to protect the contacts from wear and tear.

The contact size of D-Sub contacts varies from size 1-45 depending on the applications they will be used for. The numerical value given represents the width of the contact at its largest point. As such, smaller application areas dictate lower values while more demanding applications require higher contact sizes.

D-Sub contacts are commonly found on connectors such as VGA, PS/2, Serial, and DB-37. VGA connectors, for instance, will typically contain three D-Sub contacts: one for a power line, one for a signal line, and one for a ground line. Meanwhile, connectors such as Serial contain nine D-Sub contacts, each assigned a specific task.

The working principle of D-Sub contacts revolves around a simple conductive system. The contacts secure one end of the wire or cable to create a continuous electrical pathway which will in turn enable data signals to be transmitted. The contacts must be properly aligned in order for the connection to be established and working correctly, as an offset contact may cause the device to interpret the signal incorrectly or not at all. Furthermore, D-Sub contacts should also be regularly checked and maintained, as over time the contacts may become loose or corroded, thus weakening the signal strength.

In conclusion, D-Sub contacts are essential components of many electronic devices, and are used to securely transfer data in a variety of application areas. They are important for devices such as computers and gaming consoles, and are easily identifiable due to their characteristic D-shaped design. Furthermore, the working principle of D-Sub contacts is simple and straightforward, relying on the contacts to establish a secure electrical connection between two points.
