Product Description

 Reliable 4.5GHz High Frequency Rotary Joint with ISO/Ce/FCC/RoHS
Dual Channel Rotary Joint 

 A radio frequency rotary joint (or swivel joint) is a mechanism used to transfer fluid (under pressure or vacuum) from a stationary inlet to a rotating outlet, preserving and isolating the fluid connection. Radio frequency slip rings are engineered to endure a wide range of temperatures and pressures for a variety of conditions and environments. In addition, Radio frequency rotary joint may integrate multiple passages and handle different types of fluid simultaneously.
Radio frequency rotary joint typically used  in satellite communication solutions to the military, broadcast media, and corporate customers.
