DBMMD21C1SJ

D-Sub Connectors

DBMMD21C1SJ, also called a D-subminiature connector, is a type of electrical connector widely used in computing and other electronics for various connections. It has two parts, a plug and a socket, which can be mounted on a board or cable and is used to provide electrical connections between two or more devices. The common types of D-sub connector include 9-pin, 15-pin, 25-pin, 37-pin, and 50-pin, which are distinguished by the number of pins they contain.

Application Field

D-sub connectors are widely used in various applications, such as digital audio, computer peripherals, serial networks, industrial control, and so on. In digital audio, DBMMD21C1SJ is commonly used to connect the audio source to the speaker, providing a reliable and stable connection for sound. It is also used in computer peripherals, such as mouse, keyboards, and so on, enabling them to transmit electronic signals properly. In serial networks, these connectors are commonly used to interface serial devices, such as modems and routers, to enable high-speed communication. Lastly, DBMMD21C1SJ is often used in industrial control systems, such as sensors, actuators, and other components, to provide reliable electrical connections.

Working Principle

The working principle of DBMMD21C1SJ is quite simple and involves two parts—the plug and the socket. First, the plug is inserted into the socket, forming a mechanical connection. The plug then connects pins of the socket one by one, making electrical contact. At the same time, the pins on the plug make a connection with the terminals on the socket, forming a complete electrical connection. Once the connection is established, current and voltage travel through it, and the signal is transmitted between the devices.

Conclusion

DBMMD21C1SJ is a type of electrical connector widely used in computing and other electronics, such as digital audio, computer peripherals, serial networks, and industrial control systems. Its working principle is quite simple, involving two parts, the plug and the socket. The pins on the plug make a connection with the terminals on the socket, forming a complete electrical connection. With its reliable and secure connections, it helps enable efficient transmission of electronic signals.
