To Discuss Your Application Needs
Proterial specializes in building complex fine wire bundles that are traditionally found in ultrasound imaging environments for medical probe cables in both medical and non-medical applications where precision and performance are paramount. This expertise can be expanded upon to other applications such as endoscopes, catheters, and animal probes.
Micro-coaxial cable is used in a wide array of precision medical products and cabling applications, where limited space, high reliability, high-sensitivity and outstanding signal, capacitance and impedance characteristics are important.
Ideal for ultrasound probes, catheters, endoscopy, oximetry systems, sensors, robotics and industrial automation and inspection. We offer a full range of standard sizes from 32 to 50 AWG using high-strength silver-plated or tinned-copper alloys that are rated to +200°C. Our micro-coaxial cable is a market leader due in part to our proprietary high-strength alloys with outstanding low-loss characteristics.
Features and Benefits:
We offer a broad selection of copper alloy wire with precision wire gauges ranging from 36 AWG to 50 AWG. These superfine, high strength, highly conductive 7 strand constructions are useful for small diameter flexible cables. We offer standard 50 & 60 Ohm impedence products.

Proterial’s advanced foam PFA extrusion process delivers low capacitance cable with reliable performance. We utilize a polyester tape skin over the foam to deliver the dielectric withstand voltage required by the medical industry. 38 AWG to 48 AWG wire sizes are available. These are 70, 75, and 85 Ohm impedance cables.
Proterial solid conductor constructions combine all the attributes of the stranded wire coaxials while offering a slightly smaller diameter with improved current carrying capacity, and lower loss. Features and Benefits:
The chart below is a useful tool for understanding the behavior of a single coaxial (with 7 strand conductors) in relation to size, group bundling, frequency and flex life.
In addition to Micro-coaxial cable, Proterial offers high performance single lead wire which is at the heart of our Micro-coaxial line. Providing extremely thin wall PFA and our standard alloy materials, our lead wire offers the same exceptional characteristics that customers have come to expect.
Our bundles can include many different styles of cables in addition to micro-coaxial cable. Proterial offers various tubing for air or fluidics, specialty optical fiber for data and power transport, or just basic data and power copper wiring. We custom design each cable for whatever evolving and demanding need occurs. Hybrid bundling of a multi-function cable is also available.
Features & Benefits:
A number of micro-coaxials are bundled for ultrasound probe cable. Typical design specifications should include the style of coax, the number of coax, the shield configuration, flexibility requirements, type of sheath and sheath color. Custom designs are also available upon request.
The applications for medical probe cables, typically used in ultrasound diagnostic apparatus, can be expanded to other medical equipment such as endoscopes, catheters, and animal probes. Proterial Cable offers customized cable to meet specific needs depending on the application or equipment.
Our high strength micro-coaxial cable with ultra-thin medical grade jacketing is the optimal solution for advanced catheter applications.
Features and Benefits:
Standard twisted pairs can be used for differential signal lines (putting equal but opposite voltage on each of the wires). This ensures that noise effects are significantly reduced. Typically twisted pairs reach their limits around ~2-4 Gbps while twinaxials can perform well at higher transmission rates. Twisted pairs may have better flex characteristics over twinaxial designs.
Twinaxial constructions have the pairs laid parallel to each other. This approach allows for very high bandwidth applications greater than that of common twisted pairs. They result in lower attentuation due to a shorter travel distance, better impedance characteristics and better control of skew within the pair. Typically twisted pairs reach their limits around ~2-4 Gbps while twinaxials can perform well at higher transmission rates. Twinax signals are especially good at 5 Gbps+ up to and as high as 25 Gbps / channel currently.
Thermal Management of Medical Cables and Devices is becoming increasingly challenging and critical to the reliability and usability of advanced surgical, imaging and implantable devices. As the trend for lighter, smaller and more operable cables continues so will the trend for finer wire with increased coaxial counts. This will drive the ongoing need for improved cable and device thermal management. When designing a cable, the shield design can have a significant impact on thermal resistance. Secondly, an improved shield can be further improved with a proper thermal connection. Contact Proterial for additional support to maximize your designs’ performance.
