Medical cable assemblies connect sensors, imaging modules, patient monitors, and surgical instruments to their control units. Unlike general industrial harnesses, these assemblies must maintain electrical stability while meeting stricter requirements for patient safety, sterilization compatibility, and long-term reliability in clinical environments. Shenzhen REUNION Electronic Co., Ltd. has produced medical-grade cable assemblies since 2011 under an ISO 13485 quality management system, with design and manufacturing processes aligned to the documentation and traceability expectations of medical device manufacturers.
Medical Cable Assembly often falls within the scope of IEC 60601-1 for electrical safety, which places limits on leakage current, dielectric strength, and insulation integrity. REUNION works from customer specifications to select materials and construction methods that support compliance with these requirements. Each production lot is traceable through the ERP system, linking raw cable stock, connector batches, and final test records so that medical customers can retrieve documented evidence for audits or regulatory submissions.
Cable jackets and overmolding compounds used in medical assemblies are selected for biocompatibility, chemical resistance, and tolerance to disinfection methods. Silicone offers flexibility and withstands repeated autoclave or ethylene oxide sterilization. TPU provides abrasion resistance and compatibility with alcohol-based disinfectants. For connectors that may contact patients or clinicians, housing materials such as PSU or PEEK are preferred for their low extractable content and resistance to stress cracking. These material choices apply to Plastic Push-pull Connector designs commonly found in medical devices where non-conductive surfaces and lightweight construction are required.
Medical equipment frequently uses Push-Pull Connector interfaces because they allow quick, one-handed connection and deliberate release without rotational force. This is valuable in clinical settings where staff wear gloves and need to connect or disconnect cables rapidly. When the assembly must withstand fluid exposure during procedures or cleaning, Waterproof Connector sealing elements can be integrated into the connector and cable transition to achieve IP67 or higher. REUNION tests sealed medical assemblies for ingress protection and verifies that the cable-to-connector junction remains leak-free after repeated mating and flexing.
The Shenzhen facility operates 10 assembly lines with about 150 employees, supporting both low-volume prototype builds and full production runs. In-house processes include wire cutting, stripping, soldering, overmolding, and final electrical testing. For medical projects, REUNION maintains device history records and can provide certificates of conformance, material certifications, and test reports tied to each assembly lot. The engineering team, supported by 13 patents and 2 software copyrights, handles over 30 customized projects annually and can assist with reverse-engineering from existing samples when original documentation is incomplete.
Yes. Depending on the customer's quality agreement, REUNION can supply material certificates, inspection records, and final test reports. Lot-level traceability is maintained through the ERP system, allowing each finished assembly to be traced back to its raw cable and connector batches.
Sterilization compatibility depends on the selected cable jacket, overmolding compound, and connector materials. Silicone, PSU, and PEEK-based assemblies can typically withstand steam, ethylene oxide, or hydrogen peroxide plasma sterilization. REUNION specifies material grades according to the intended sterilization method and number of cycles.
Push-pull connectors are common in medical applications because they provide secure latching with simple operation. Plastic housings are often preferred for patient-connected equipment due to electrical isolation and low weight. REUNION can integrate these connectors with overmolded cable exits to reduce leakage paths and improve cleanability.
