Coaxial Connectors (RF), also known as “coax” connectors, are used in electronics to connect two or more wires together and carry signals across various frequencies. They are commonly used in audio, video, and radio transmissions. The particular connector under discussion is the SF2921-61506-1S, an RF coaxial connector designed for medium-power, 50 ohm applications.

Applications

The SF2921-61506-1S is designed for medium-power applications that require both high-performance and reliable connections. These applications include base-station antennas, active phased arrays, direct broadcast satellite (DBS) antennas, CATV antennas, and WiFi/cellular communications systems. It is also suitable for use in systems where 50 watts or less of power is required, such as in satellite interactions and aviation systems.

Working Principle

The SF2921-61506-1S consists of an outer shell and an inner contact sleeve. The outer shell is made of nickel-plated aluminum and is designed to protect against the elements. The inner contact sleeve is made of stainless steel and is designed to convey the electrical signal from the outer shell to the inner conductor. The inner conductor is a flexible braid wire which is designed to minimize signal loss and maximize the strength of the connection. The braid wire is held in place by the outer shell and the inner contact sleeve.

When connecting two RF connectors, the braid of the first connector is Push Pulled or soldered to the braid of the second connector. This creates a solid connection between the two conductors and the signal can then be transferred. The SF2921-61506-1S connector is designed to be watertight when connected, making it ideal for outdoor applications.

Conclusion

In conclusion, the SF2921-61506-1S is a medium-power RF connector designed for applications that require both high-performance and reliable connections. It features an outer shell made of nickel-plated aluminum, an inner contact sleeve made of stainless steel, and a flexible braid wire designed to minimize signal loss and maximize the strength of the connection. When connecting two RF connectors, the SF2921-61506-1S is designed to be watertight and is ideal for outdoor applications.
