205A123-4-0 Application Field and Working Principle

Circular connectors are widely seen in many fields such as automation, aerospace and computer and telecommunication systems. Among them, the style of 205A123-4-0 is very common and often used because of its excellent performance and various application fields. What is the application field and working principle of this kind of connector?

Application Fields

205A123-4-0 circular connectors, originating from the MIL-STD-connector series, are widely used in electronic measuring instruments, automation instruments, aviation, communication, medical instruments, ships, rail transportation and other industrial control fields. They are often used to connect serial ports, control circuits, and modular devices, and are used in industry as well as in the telecom and medical industries.

Working Principle

The main structure of the 205A123-4-0 consists of five parts: the shell, coupling nut, insulation pins, terminal blocks, and contact pins. When the connector is assembled, the terminal blocks are placed on both sides of the shell with the contact pins in the terminal blocks. When the coupling nut is tightened, the terminal blocks are preloaded to mechanically and electrically link the connector pins. The coupling nut has a fixing hole in the center and can be clamped to the external device by means of a lockring or other fastening parts.The main roles of the contact pins are to transmit, receive, and redirect the electric signals, and to connect the external cable. The outer shell is the outermost part, which can effectively prevent dust and water from entering the connector and ensure the normal operation of the connector. At the same time, the heat dissipation effect of the shell can make the electric current bear load within a certain normal range and will not affect the normal operation of the connector.

Conclusion

To sum up, 205A123-4-0 circular connectors are widely used in the automation, aerospace and medical industries, and its excellent performance ensures the normal operation of the connector. Its application field is very broad and its working principle is very simple.Thanks to its shell, terminal blocks and contact pins, this kind of connector can work reliably and stably in various harsh environment. Therefore, its application field and working principle should be taken into consideration when choosing a connector.
