Capsulated Slip Rings for Compact Rotating Assemblies
A capsulated slip ring is a sealed cylinder with a solid shaft: the rotor turns, the stator stays still, and both ends leave the body as flying leads. It is the smallest way to get a rotating electrical connection into a tight assembly.

What This Family Is For
The constraint
In dome cameras, small robot wrists, test rigs and medical instruments there is no room for a flanged through bore unit, and the cable still winds itself up after a few dozen turns.
How INGIANT answers it
INGIANT capsule units run from roughly 5.5 mm to 80 mm outside diameter, with precious metal contacts, an aluminium or engineering plastic housing and pre-terminated leads, so the part drops into the assembly without a mounting redesign.
Who buys this family
Builders of CCTV and PTZ cameras, small robots, laboratory and test equipment, winding and wrapping machines, medical devices and instrument turntables.
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.

Capsulated Slip Rings Questions Engineers Ask
How small can a capsule slip ring be?
The smallest models in this range are around 5.5 mm in outside diameter. The exact envelope depends on how many circuits and how much current per circuit you need.
How is a capsule slip ring fixed in place?
The stator body is clamped or screwed to the frame and the rotor shaft is coupled to the rotating part. Use a flexible coupling or an anti-rotation arm so no radial load reaches the unit.
Do capsule units need lubrication or servicing?
No. The precious metal contact pairs are designed to run maintenance-free for the rated number of revolutions.
