VB40-2062

Coaxial connectors, or RF (radio frequency) connectors, are used to connect two electronic devices together. RF connectors are used in a variety of applications, including the transmission of radio and TV signals, radar, microwave signals, telecommunications, GPS and other telecommunications systems.

Characteristics of RF Connectors

One of the most important characteristics of RF connectors is its impedance. This is the measure of the opposition to the flow of electrical current and is expressed in ohms. An impedance of 75Ω offers high performance, is particularly resistant to electromagnetic interference and is generally considered best for data transmission.

Impedance also depends on the inner diameter of the coaxial cable: the standard being 50Ω for most cables of this type. This is the preferred value from a safety perspective and, of course, also from a performance perspective. Another important feature of RF connectors is the type and performance of the contact. This could be a crimped contact, a Split Pin, a compression-style contact, or a stiff metal contact.

VB40-2062 Application Field and Working Principle

The VB40-2062 is a two-piece RF connector manufactured by Johanson Technology. It features a threaded coupling mechanism which provides a secure connection, minimum RF reflections, and high impedance. It is designed for a wide variety of high-frequency applications, such as cellular, GPS, Wi-Fi, Bluetooth, and WiMAX.

The VB40-2062 has a 4.2 mm thread pitch with an associated contact size of 32 AWG. It is a Plug and Jack configuration and features an IP68 environmental test rating. The plug’s coupling nut is made of brass and the thread pitch is 4.2 mm (0.165 in). This connector is ideal for applications requiring a high degree of performance and reliability.

As for the working principle, the VB40-2062 Incorporates a friction sleeve which enables the user to quickly lock two distinct connectors together without any tool. This threading provides a secure, low-loss connection between the connector and the cable, improving RF performance, even at very high frequencies. It also ensures a high quality electrical continuity between the two parts of the connector.

Conclusion

The VB40-2062 connector is a highly reliable and robust two-piece RF connector designed for high-frequency applications. It features a threaded coupling mechanism which provides a secure connection, low RF reflections, and high impedance. It is particularly well suited for applications such as cellular, GPS, Wi-Fi, Bluetooth, and WiMAX due to its high-performance characteristics and environmental testing rating.
