Cable Assemblies for Medical Devices
In a medical assembly, the parts that fail are rarely the parts the datasheet talks about. They are the strain relief where a lead is pulled, the jacket where it meets a cleaning agent, and the documentation gap that appears when a device goes into an audit.
What this application demands
These are the constraints that change the design. Everything else is a normal cable.
- Chemical and cleaning exposure
- The jacket and overmold have to survive the cleaning agents actually used on the device, not just a generic ‘chemical resistance’ claim.
- Sterilization compatibility
- Material behaviour under the sterilization method you use is a material selection problem. We will tell you which of our compounds are and are not appropriate for it.
- Low-noise lead sets
- Triboelectric noise from cable movement matters at low signal levels. Construction, shielding and strain relief all contribute.
- Strain relief at the handset end
- The point where a lead is grabbed and pulled. This is where overmold geometry earns its cost.
- Material traceability
- Certificates traceable to the material lot, retained under your part reference.
Typical builds
- Patient monitor lead sets and extension cables
- Handheld device and probe cables with overmolded strain relief
- Low-noise shielded sensor leads
- Silicone-jacketed high-temperature assemblies
- Reusable cable sets rated for repeated cleaning
What we can and cannot document
We build to your drawing and your documented acceptance criteria. We supply material certificates with lot traceability, first-article inspection reports in your format, and 100% continuity and pinout testing. Where a regulated device requires a certified quality management system, biocompatibility documentation or a submission package that we do not hold, we tell you at quotation rather than at final inspection.
If your device programme needs a supplier with a specific certification, ask us directly. An honest ‘no’ at quotation is cheaper for you than a surprise at audit.
What we ask before quoting
Answer these with the drawing and the quotation will be meaningful on the first pass.
- Cleaning agents and sterilization method the assembly will see
- Material or biocompatibility requirements, if any
- Flex or bend cycles expected at the connector and handset end
- Documentation you need: material certificates, FAI report, test data
- Mating connector part numbers and annual volume
Send the specification and the mating connectors
We will confirm what the cable has to survive, flag anything that will cost you money without adding function, and quote against your drawing.
