Product Overview

Ingiant at a Glance

This is a capsule unit with a 78 mm body, carrying 6 to 48 rings (Customizable) circuits across a continuously rotating joint. Power and signals cross the joint through sliding precious metal contacts, so the moving assembly can turn indefinitely in either direction.

  • 6 to 48 rings (Customizable) circuits
  • Ø78 mm
Key Benefits

What This Model Gives the Machine

Unlimited rotation without cable wind-up

The rotating side keeps its electrical connection through continuous 360° turning, so the machine never has to stop and unwind.

Maintenance-free contact system

Precious metal contact pairs are designed to run without lubrication or servicing for the rated life, so there is nothing to schedule on this axis.

Fits a 78 mm interface

The 78 mm envelope keeps the joint inside the space the assembly already has, so the surrounding design does not have to change.

Stable transmission under vibration

The contact geometry is designed so that shock and vibration do not translate into resistance variation on the signal rings.

Backed by a 12 month warranty

12 months from date of sale; free repair or replacement for quality problems not caused by human damage

Who It Is For

Engineers Who Specify This Part

OEM engineering teams, defence and research institutes, special machine builders and integrators who cannot design around a catalogue part.

Application scenarios

Problems It Solves

Three Failures It Removes

Failure 1

Cables that have to follow a rotating part fail at the flex point, and the failure always happens in production rather than on the bench.

Failure 2

Slip rings that need periodic servicing pull a machine out of production for a job that should never have been on the schedule.

Failure 3

Fitting a rotating connector after the mechanical design is frozen usually means cutting into the envelope somewhere it was not planned.

Manufacturing and Quality Control

How the Unit Is Built and Checked

Machining runs on the in-house CNC centre across roughly 6000 m² of research and production space, and assembly is done by the production team in Jiujiang.

Before despatch each unit is checked for insulation resistance, insulation strength, dynamic resistance variation and functional signal performance, using the test equipment and procedures held under the ISO 9001 and GJB9001C quality systems.

Comparison

How It Compares With the Other Formats

A through bore unit keeps the centre of the axis clear but needs more radial space and a flange. Choose the capsule format when nothing has to pass through the middle and the envelope is the binding constraint.

Use Guide

Fitting and Commissioning

Mount the stator, not the load

Fix the stator to the frame through the flange or the anti-rotation arm and couple the rotor to the rotating part. The slip ring must never be used as a bearing — the machine's own bearing carries the load.

Respect the lead route

Leave a service loop at both ends and keep the bend radius above the cable's own minimum. Most field failures start at a lead that was pulled straight.

Separate power and signal runs

Route the power leads and the signal leads apart from each other after they leave the unit, and ground the shield at one end only.

Commission at low speed

Turn the assembly by hand first, check continuity on every circuit, then run up to speed and confirm the signal quality before the machine goes into production.

FAQ

About Ingiant

How many circuits does DHS078 have?

This build has 6 to 48 rings (Customizable) circuits, rated 0–440V AC/DC at 2A / 5A / 10A / 20A per ring. The ring count can be changed on a customised build — send the number of single wires that have to cross the joint.

What does the 78 mm in the model number refer to?

It is the outside diameter of the body. In DHS078 the digits after the series letters give that dimension in millimetres, and the number after the dash is the circuit count.

How long does delivery take?

Standard products ship in 7–15 days. Simple customised products take 10–20 days and complex customised products take 15–40 days. The delivery port is Jiujiang, China Mainland.

Can this model be modified for my machine?

Yes. Send the rotating speed, the installation type and size, the circuit count, the voltage and current per ring, the signal types and their parameters, the operating temperature and the IP requirement, and the unit is redesigned around them.
