RF Rotary Joints and Coax Slip Rings for Rotating Antenna Systems
An RF rotary joint carries microwave and coaxial signals through a rotating interface while holding VSWR and insertion loss steady through the full turn.
All 27 RF Rotary Joints and Coax Slip Rings Models
Listed in full, each with its own parameter table.
What This Family Is For
The constraint
On a rotating antenna or radar head the feed cannot be allowed to wind, and any variation in the rotating contact shows up directly as phase and amplitude ripple in the received signal.
How INGIANT answers it
INGIANT builds single and multi-channel RF rotary joints and coaxial slip rings, and integrates them with power and signal rings so one body feeds the antenna and its drive and control circuits.
Who buys this family
Radar and surveillance system builders, satellite and communications antenna manufacturers, defence electronics teams and test equipment designers.
Standard Values Across This Family
These are the catalogue values that appear on most models in this family. Every one of them can be changed on a customised build.
Rotating speed
Catalogue units are rated 0–600 rpm. Lower and higher speed designs are built to order.
Working temperature
-40 °C to +65 °C on standard builds, with wider ranges designed against the application.
Protection level
IP54 as standard, with sealing grades up to IP68 where the environment demands it.
Insulation
Insulation resistance ≥1000 MΩ at 500 VDC, insulation strength 1500 VAC at 50 Hz for 60 s.
Contact system
Precious metal ring and brush pairs with dynamic resistance variation below 10 mΩ.
Lead wire
Colour-coded Teflon insulated tinned stranded flexible wire, 500 mm + 20 mm as standard.

RF Rotary Joints and Coax Slip Rings Questions Engineers Ask
Can an RF channel be combined with power rings?
Yes. The catalogue includes hybrid units such as a 73 circuit power stack combined with one radio frequency channel in a single body.
What determines the price and lead time of an RF rotary joint?
The frequency band, the channel count and the VSWR and insertion loss limits. Send those with the rotating speed and the mechanical envelope and INGIANT will quote against them.
Are COAX slip rings and RF rotary joints the same thing?
They solve the same problem. A coax slip ring transfers a coaxial signal through a contact path, while an RF rotary joint uses a matched microwave structure for higher frequencies and tighter loss limits.
