D-sub connectors are electrical connectors used for many types of communication and I/O applications. The D-sub connector family includes several types of plugs and sockets for many different types of wiring schemes and custom configurations. Among the many types of D-sub connectors available, the DBMV21C1PNK87 is of particular interest because of its specific application field and working principle.

The DBMV21C1PNK87 is a type of D-sub miniature VGA connector, commonly used to connect computers to other computers, displays, and other video equipment. The connector is used in a variety of applications, including aerospace, military, and industrial applications. It is made up of three connectors: a 3-conductor socket, a 9-pin male plug, and an 8-pin male plug.

The 3-conductor socket is used for two video signals (component and composite video) and one ground. It connects to the motherboard and receives two video signals and one ground signal. The 8-pin male plug is used to provide 12V DC power to the connected components. The 9-pin male plug is used to transfer analog RGB input signals from the connected components.

The working principle of the DBMV21C1PNK87 is simple. The VGA (Video Graphics Array) connector on the computer sends analog RGB signals to a connected device (e.g. monitor or projector). The connected device will then interpret the RGB signals and display the content on its screen. The 12V DC power signal from the 8-pin male plug will keep the connected devices powered on. Lastly, the 3-conductor socket provides a GND connection between the computer and the device, which helps ensure a stable connection.

Overall, the DBMV21C1PNK87 is a versatile and reliable D-sub connector that is suitable for a wide range of applications. Its broad application field and simple working principle make it an ideal connector for any high-quality video connection.
