Rotary Joints
Rotary joints are needed wherever signals have to be transmitted between a fixed platform and a second platform in continuous rotation. Such applications include traditional radar technology for air traffic control or anti-missile defence, medical engineering, V-Sat and SatCom technology as well as industrial applications like TV camera systems or cable drums that allow sensitive cables to be wound up without twisting them, thus increasing their reliability.
Special benefits of SPINSTAR rotary joints are their compact design, excellent VSWR and low insertion loss, low variation of transmission properties during rotation, and high crosstalk attenuation between the individual channels over the whole frequency range.
