HD-SDI Slip Rings for Uncompressed Video From a Rotating Camera
An HD-SDI slip ring carries uncompressed high definition video from a camera on a continuously rotating platform to the fixed recorder or switcher, without dropped frames at the joint.
All 15 HD-SDI Slip Rings Models
Listed in full, each with its own parameter table.
What This Family Is For
The constraint
Broadcast and inspection cameras on pan-tilt heads and rotating rigs need an unbroken high frame rate video path, and any contact noise in the rotating joint becomes a visible artefact.
How INGIANT answers it
INGIANT HD-SDI units combine the video channels with power and control rings in one body, so the camera, the drive and the control bus all pass through a single rotating interface.
Who buys this family
Broadcast and studio rig builders, PTZ and surveillance camera manufacturers, pipeline and tank inspection system builders and stage equipment manufacturers.
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.

HD-SDI Slip Rings Questions Engineers Ask
How many HD-SDI channels can one unit carry?
Single and multi-channel HD-SDI slip rings are available, and video channels are combined with power and signal rings to suit the camera head.
Can I also run pan and tilt power through the same slip ring?
Yes. Power and control rings sit in the same stack as the video channels.
Is fibre a better choice than HD-SDI for long runs?
For long distances or electrically noisy sites a fibre optic rotary joint keeps the signal isolated and loss low. INGIANT builds both, and combines them when needed.
