D-Sub Connectors

The 17342821 is a D-sub connector so before we jump into the application field and working principle let\'s first understand what is a D-sub connector.A D-sub connector is a type of connector used in communication and computer system. It is also known as DE-9 or more commonly as D-sub. It’s an abbreviation for a “D-shaped connector.” It’s solid shell design consists of stamped female and machined male contacts. This connector usually consists of two or more parallel rows of pins or sockets often surrounded by a D-shaped metal shield. It is a common type of connector used in construction and equipment wire harnesses, as well as patch cables.The 17342821 is a D-sub connector mainly used as an interface between a PC motherboard and a monitor cable. This connector uses a DE9M connector type as a male connector and a DE9F type as female connector. It is defined by its DE-9 form factor, utilizing 9 pins for communication.The application field of 17342821 lies mostly in the computer and communication field. It is mainly used for the device-level control, signal transmission, and power supply. As the common media of the electrical interfaces between devices, it’s used to maintain the stable and reliable connection for the electric signal transmission. The 17342821 works via pin connection. In this connector, the contacts of a female D-sub connector sockets are inserted into the contacts of a male D-sub connector pin. When these two housing are mated, the contacts ensure high reliability, contact separation force, and excellent corrosion resistance. As the two connector housings are mated, electrical connections are made between pairs of pins. The 17342821 features good anti-interference performance. As the signal transmission speed increases, the number of lines becomes more and more, which means that the contact structure of D-sub connectors should be as stable as possible to guarantee signal transmission. This connector provides a good solution to this need.The D-sub connectors are widely used in industrial instrumentation and automation, data acquisition systems, LED lighting, medical devices, computer peripherals, and many other applications. With the 17342821 D-sub connectors, the compatibility of data bus pathways among multiple devices improves and so does the connection stability of data transmission and power supply. This ensures the accuracy of data transmission without any data errors.In summary, the 17342821 is a kind of D-sub connector whose application field lies in the computer and communication field. It features a DE9M connector type as a male connector and a DE9F type as female connector. It works via pin connection and consists of two or more parallel rows of pins or sockets often surrounded by D-shaped metal shield. The 17342821 is therefore used for keeping the reliable connection for the electric signal transmission with good anti-interference performance. It is used in many applications including industrial instruments, automation systems, LED lighting, medical systems, and computer peripherals.
