D-Sub Connectors

D-Sub Connectors, also known as D-Subminiature Connectors, are a type of electrical connector widely used in our daily life. One of its most prominent features is that it has two rows of pins or sockets arranged in parallel. It is designated by alphabets. For example, the model number 6843W3K202461 stands for a 9-pin D-Sub Connector. The 6843 stands for “DB” (D-Subminiature), W3 stands for “09” (indicating 9 pins), K stands for “180°” (signifying the contact angle), 20 stands for “2M” (noting the shell size is 2mm) and 2461 stands for “G9” (representing the contact type).

Application Field

D-Sub connectors has many applications. As one of the most popular and widely used connecters, they are usually used for computer and telecommunications. As 9-pin connector variant of DB type, 6843W3K202461 utilizes in Advanced Technology Attachment (ATA) data transfer interface, IEEE 1284 Parallel Port Printer Connector, Serial Port, the Apple Desktop Bus (ADB), RS-232 connectors, and other devices. Choosing the correct D-Sub connector depends on the application and the signal type. 10-pin D-Sub connecters are commonly used in RS-232 port and the interface of serial digital video signal.

Working Principle

The 6843W3K202461 D-Sub Connector is a male pin connector, and the female side is a free socket that will accept male pins from another side of the connector. Iron plated copper female sockets are inserted into the plastic housing which has a hole and a locating key on it. The male pins are pressed into cavities of the plastic housing for a firm and stable connection. A spring pressure is placed on the male pin to keep the male pin in contact with the socket when the connector is turned or twisted. This can ensure a safe and reliable connection by reducing electrical noise.

Conclusion

6843W3K202461 D-Sub connectors, with its excellent functioning features, are widely used in many industries. By connecting computer and telecommunications devices, these connectors provide reliable and secure data communication, making our world more connected. As we continue to develop new technologies and products, D-Sub connectors will surely remain an integral part of our lives.
