The 142-5439-001 rf coaxial connector is used for many functions for each of the application fields discussed. It is suitable for applications in digital and analog signal transmission, data transmission, world broadcasting, etc.

Working Principle

The 142-5439-001 rf coaxial connector consist of an outer metal jacket that houses an insulator. Within the insulator is a center pin, which is surrounded by a dielectric sleeve. The outer metal jacket and the center pin of the connector are conductive and can carry the signal from one device to another. The outer metal jacket of this rf connector also provides the shielding from electromagnetic interference (EMI). It also provides the needed structural support between the two sides of the connection. The insulation between the center pin and the outer metal jacket of the connector ensures the electrical current does not flow across the connector and only flows through the center pin. The working principle of the 142-5439-001 rf coaxial connector relies on the electromagnetic field created in between the center pin and the outer metal jacket of the connector. The center pin of the connector transfers the signal from one device to another while the dielectric sleeve keeps the signal in the center and away from the outer metal jacket. The outer metal jacket then provides the needed shielding against EMI.

Conclusion

The 142-5439-001 rf coaxial connector is an efficient and reliable connector for a wide range of applications. It is a suitable choice for analog and digital signals, data transmissions, world broadcasting and it provides protection against electromagnetic interference. The working principle of this type of connector relies on the electromagnetic field created between the center pin and the outer metal jacket.
