High Frequency Rotary Joint

Coax rotary joint also could be called high frequency slip ring or connector, which is used for continuous rotation device to transmit hi-frequency signal between fix part and rotary part. This kind of rotary joint can be an element which installed on the cable or instrument as transmitting or breaking the line of electrical connections. The max frequency range reach up to 40GHz (or higher ) analog signal and high speed digital signal.

If you have specific customized requirement, please feel free to consult us so that our sales engineer could recommend the most suitable product to you for you reference.
