Product Overview

DHK065-6-10A at a Glance

DHK065-6-10A puts 6 circuits through a 65 mm bore without limiting rotation. It sits between the fixed and the rotating side of a machine so cables never wind up, and it is supplied by JiuJiang Ingiant Technology Co., Ltd as a standard or customised build. On this model it combines 10 power (A rating) channels with the electrical rings in one body, sealing is rated IP54, rated speed is 0~600rpm.

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. Rated speed is 0~600rpm.

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. Dynamic resistance variation stays <10MΩ.

Fits a 65 mm interface

The 65 mm bore lets the shaft, cable bundle or air line pass straight through the axis, so the surrounding design does not have to change.

One axis carries 10 power (A rating) channels

Stacking separate rotary joints on one shaft costs length, alignment and reliability. Combining them in a single body removes those interfaces.

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

Designers of rotary tables, index drives, cable reels, packaging and filling machines, harbour and construction cranes, robot joints and pan-tilt heads.

Application scenarios

Problems It Solves

Three Failures It Removes

Failure 1

Rotation limited to ±180° forces an unwind move into every cycle, and that time is lost on every part the machine makes.

Failure 2

Contact noise on a rotating joint shows up as sensor drift or dropped packets long before it shows up as a failed continuity test.

Failure 3

Sourcing several rotating joints for one axis multiplies lead times and alignment tolerances.

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.

Customization Options

What Can Be Changed on This Build

  • Circuit count, and the current and voltage rating of each ring
  • Bore diameter, overall length and mounting interface
  • Added channels — Ethernet, USB, HD-SDI, optical fibre, RF coaxial, pneumatic or hydraulic passages
  • Sealing grade from IP51 to IP68, and housing material
  • Lead length, lead specification, connector termination and outlet direction
  • Quality grade S Standard, I Industrial or P Premium against the revolutions expected

Simple customisation 10–20 days. Complex customisation 15–40 days.

Comparison

How It Compares With the Other Formats

A capsule unit is smaller but leaves nothing free at the centre of the axis. Choose the through bore format when a shaft, a cable bundle, an air line or a fibre has to pass straight through the joint. Against separate single-purpose joints, this hybrid build puts 10 power (A rating) channels and the electrical rings on one axis, which removes an interface and a set of tolerances.

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

Standard lead length is 500mm + 20mm Standard product outline drawing. 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

Rated speed is 0~600rpm. 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 DHK065-6-10A

How many circuits does DHK065-6-10A have?

This build has 6 circuits, rated 0~240 VAC/VDC at 2A.5A.10A.15A.20A. 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 65 mm in the model number refer to?

It is the bore diameter. In DHK065-6-10A the digits after the series letters give that dimension in millimetres, and the number after the dash is the circuit count.

Is IP54 enough for my application?

IP54 is the rating on this build. Tell INGIANT the real exposure — dust, splash, washdown, outdoor weather or immersion — and the sealing grade is set against it, with options available up to IP68.

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.
