Medical Device Wiring Harness


Wiring harnesses are circuits of medical electronic devices. Medical devices wiring harnesses are made by cutting electronic wires of appropriate length according to drawings, and then pressing contact terminals (connectors) made of copper stamping with wires and cables. Bundle the components that make up the connecting circuit.


For example, the display screens of all kinds of medical equipment need wire harness for connection. And it needs really high quality wire harness. Ventilators, defibrillators, oxygen concentrators, monitor, Anesthesia machine, Oxygen generator, Electric wheelchair, Silence of gearbox and fan, MRI machines, X-rays, and electronic beds all require wiring harnesses to improve performance and usability.


  • Our wire harness has passed a total of 15 performance related testing projects in mechanical, physical, electrical, and other aspects. High quality and good performance.

  • We use high-quality materials, products with strong flexibility, acid and alkali resistance, oil resistance, moisture resistance, mold resistance, flame retardancy, wear resistance, corrosion resistance, oxidation resistance, waterproofing, dust prevention, UV resistance and other characteristics, using high-quality environmentally friendly TPU materials, strong insulation performance, wear resistance, corrosion resistance, and long service life; High quality wire core, heat-resistant, fire-resistant and flame-retardant, with a sturdy body that is not easily broken.

  • We customize the wiring harnesses of the same type - customize the length, specifications, color, etc. of the wiring harness according to your drawings or sample requirements, and provide one-on-one technical research and development services.

  • We provide customers with free samples.

  • All materials meet ROSH requirements.

  • Processing technology: terminal riveting, assembly of rubber shell, injection molding, production molding.

  • Application areas: Medical equipment, medical devices, power systems, photovoltaic systems, wind power stations and other renewable resources, urban rail transit.

  • The connector uses Molex, DuPont, JST, 5557-5559, 5240-2510, 08SUR-32S, and the wire uses American standard UL1007 electronic wire.

Advantages of Ronghua:
