They High frequency rotary joints include coaxial rotary joints, waveguide rotary joints, coaxial waveguide rotary joints. They High frequency rotary joints include coaxial rotary joints, waveguide rotary joints, coaxial waveguide rotary joints. They are also known as high frequency slip rings and radio frequency slip rings. High-frequency swivel couplings are specifically designed to carry high-speed serial digital signals such as high-definition, RF and microwave signals. The slip ring series supports single and multi-channel transmission of high-frequency signals. There are also hybrid solutions that support hybrid transmission of high-frequency signals with control signals, communication signals, power signals and fluidics.
