Coaxial Connectors (RF) - Adapters

Coaxial connectors, also known as RF connectors, are commonly used for connecting electronics systems that require RF signals. They are one of the most widely used connection solutions across a variety of communication systems and applications such as television sets, radios, antennas, and mobile phones. The term “coaxial” refers to the geometry of the electrical cable used for the connection, in which two concentric components are connected by a dielectric, or insulating material, so that the current cannot be disturbed or attenuated along the cable.

What is a 4940 Connector?

A 4940 connector is a type of coaxial connector designed to connect RF cables to electronic devices. It is also known as a "TNC" connector, which stands for "Threaded Nut Connector." The 4940 connector is one of the most popular coaxial connectors and offers excellent electrical performance. It is widely used in a variety of applications, such as satellites, ships, and telecommunications equipment.

4940 Application Field and Working Principle

The 4940 connector is used in a variety of applications such as television sets, antennas, mobile phones, radios and more. The connector is designed to reliably provide connection with RF signals, and the performance is rated to ensure it resists attenuation and distortion. It contains a threaded center pin to provide a mechanical connection and a dielectric to insulate the connector from interference. It also has a protective metal casing to provide a sturdy, reliable connection. The connector is designed to hold up to both high-power signals and high-temperature environments without damaging the contact surface.The 4940 connector works by creating a coaxial connection, which ensures maximum signal integrity and resistance to interference. The center conductor is insulated by the dielectric, and the outer conductor is protected by the metal housing. When the cable is connected, the connection is secure and cannot be disturbed or attenuated. The connection ensures a reliable electrical connection, even in harsh conditions such as high-power signals or high temperatures.

Conclusion

4940 connectors are widely used in a variety of applications and offer excellent performance and reliability. The connector works by creating a coaxial connection, which ensures maximum signal integrity and resistance to interference. The connection is secure and cannot be disturbed or attenuated. The connector is designed to hold up to both high-power signals and high-temperature environments without damaging the contact surface. Thanks to its excellent portability and durability, the 4940 connector is a popular choice for many electronic device applications.
