Case medical technology
Development of a robust USB cable
For a patient application, the customer requires a cable that is durable and works reliably even under high mechanical loads.
Due to the application, the cable may only have a very low line resistance and must be very thin, while providing a very high tensile strength.
The combination of a very small slim structure with an aramid tension element meant that all customer requirements could be met.
Case medical technology
Sensor cable for ventilation control
Precise control of the air flow is essential when ventilating premature babies.
The cable for such an application must be very thin and flexible and at the same time guarantee a high signal quality.
The use of very small coaxial elements enabled the most flexible and thinnest possible cable design. This means that the mechanical load on the smallest patients can be reliably reduced to a minimum.

Implementation of new regulatory requirements
Due to the new legal situation, materials containing PFAS are no longer permitted for most applications. A corresponding change to the design was requested for an established cable.
The use of PTFE in cable construction offers many advantages from a functional point of view, but is associated with problematic conditions during production and disposal. Replacing these materials is therefore often a challenge when the functional properties need to be retained.
The existing PTFE films were examined for their functional contribution and ultimately replaced with a PFAS-free winding. This had to be combined with a modified extrusion technique in order to meet the product requirements.
Fortunately, the manufacturing costs were reduced as a result of the design change.
Case automation
Application area high mountains
One customer application involves the use of cables suitable for drag chains in high alpine areas. Despite high temperature differences, the cables must remain flexible and reliably transport signals and currents.
The tried-and-tested cable design was to be optimized for this special application to ensure the necessary mechanical stability and flexibility even at temperatures of -50°C.
Through targeted research, suitable alternative materials were identified and successfully integrated. The long-term functionality was successfully proven in extensive tests.
