Product Overview

DHS064-25 at a Glance

DHS064-25 is a capsule slip ring built around a 64 mm body and 25 circuits. The stator stays with the frame and the rotor turns with the machine, so the wiring on the moving side keeps its connection through unlimited 360° rotation. On this model 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 64 mm interface

The 64 mm envelope keeps the joint inside the space the assembly already has, so the surrounding design does not have to change.

Sealed to IP54

Housing and seals are matched to the environment so dust, splash or washdown does not reach the contact surfaces.

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

Radar and surveillance system builders, satellite and communications antenna manufacturers, defence electronics teams and test equipment designers.

Application scenarios

Problems It Solves

Three Failures It Removes

Failure 1

A twisted harness inside a rotating assembly chafes against the housing until an intermittent fault appears that nobody can reproduce.

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

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

Standard lead length is 500mm + 20mm RF rotary joint parameters: RF joint parameters Channel 1 Channel 2. 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 DHS064-25

How many circuits does DHS064-25 have?

This build has 25 circuits, rated 0~240 VAC/VDC at can be customized. 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 64 mm in the model number refer to?

It is the outside diameter of the body. In DHS064-25 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.
