DHK150-68 at a Glance
This is a through bore unit with a 150 mm bore, carrying 68 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. On this model sealing is rated IP54, rated speed is 0~600rpm.
- 68 circuits
- Ø150 mm
- IP54
- 0~600rpm
- -40℃~+65℃
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 150 mm interface
The 150 mm bore lets the shaft, cable bundle or air line pass straight through the axis, 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
Engineers Who Specify This Part
Builders of inspection and subsea systems, radar and antenna positioners, filling and packaging lines, gimbals and pan-tilt platforms, and semiconductor and test equipment.
Application scenarios
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
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
Sourcing several rotating joints for one axis multiplies lead times and alignment tolerances.
Materials Contacts and Construction
Contact system
Precious metal rings and brushes, selected for low contact resistance and long wear life.
Housing
Aluminum Alloy housing, machined in-house on a CNC centre.
Insulation
Insulation resistance ≥1000MΩ @500VDC. Insulation strength 1500 VAC@50Hz,60s,2mA.
Lead wire
Colored Teflon insulated & tinned stranded flexible wire, 500mm + 20mm Standard product outline drawing as standard.
Operating environment
Working temperature -40℃~+65℃. Working humidity <70%. Protection level IP54.

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.
Certifications
- ISO 9001
- GJB9001C
- GB/T 19001-2008 / ISO 9001:2008

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.
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.

About DHK150-68
How many circuits does DHK150-68 have?
This build has 68 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 150 mm in the model number refer to?
It is the bore diameter. In DHK150-68 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.
