Coaxial connectors (RF) are commonly used in telecommunications and broadcast industries for the purpose of providing reliable signal transmission and in many other electronic applications. In this regard, the CJ20-5A coaxial connector is a widely popular form of these connectors. This article discusses the application field and working principle of the CJ20-5A.

Application Field of CJ20-5A Coaxial Connectors

The CJ20-5A Coaxial Connectors are typically found in two types: the IEC169-8/IEC169-7 (inner contact) and the EN1675-8A (inner contact). The IEC 169-8/IEC169-7 type is suitable for applications in which maximum medium voltage is 2.2kV(rms) and frequency not more than 10MHz while the EN1675-8A is suitable for applications where the maximum medium voltage is 5kV(rms) and the frequency is not more than 20MHz. The connector is suitable for numerous applications such as switchers, coaxial cable adapters, etc. The CJ20-5A also finds application in aerospace, satellite and defense industries, which require reliable signal transmission.

Working Principle of CJ20-5A Coaxial Connectors

The CJ20-5A coaxial connector operates on the principle of the electrical wave transmission. A coaxial cable consists of a central core that is covered by a metal sheath. In the case of the CJ20-5A, the central core is made of a conductor that is surrounded by an insulating medium, typically air. In this case, the wave is transmitted from the central core to the sheath, which is then propagated in the cable. When two devices are connected by a coaxial cable, the signal is transmitted and received from one device to the other.

The CJ20-5A coaxial connector also employs a shield to reduce the signal interference. The shield is typically made of braid or spiral wrap. When the shield is connected to the devices, it provides a continuous path for electrons to travel across and this helps to reduce the interference between the two devices. This is due to the fact that the shield provides a barrier that prevents electrons from leaking out and thus, allowing for better and clearer signal transmission and reception.

Conclusion

In conclusion, the CJ20-5A coaxial connector is a highly popular form of these connectors and is suitable for applications that require reliable signal transmission. The working principle of the CJ20-5A is based on the electrical wave transmission with the use of a shield for minimizing the signal interference. As such, the CJ20-5A is a great choice for applications in the telecommunications, aerospace, satellite, and defense industries.
