The Results are in: Rolling Bend Flex Test

Data cabling can be subjected to extreme conditions it wasn’t meant to withstand when installed in industrial environments or robotic control systems. These applications require a more rugged cabling solution, which is why we developed our high-flex industrial Ethernet cable assemblies. These durable cables are designed to take a beating and endure harsh conditions without damage that, in other cables, could negatively affect performance. To see just how tough our continuous flex Ethernet cable assemblies are, we decided to put them through some vigorous testing.

 

There are various methods used in continuous motion flex testing. We chose the rolling bend method. The rolling bend trial simulates real world bending and reaching conditions which is critical to getting a true result for cable performance. We tested an unsupported cable span at the point of bend/flex motion to measure the destructive flex forces involved in a continuous motion application. By attaching the cable to a rolling bend test fixture, we were able to perform flex cycling for a specific amount of time. We then re-tested the cable to measure electrical performance. Those results were compared to the original test and a physical inspection was done to find any damage to the cable.

 

What we found was that our high-flex industrial Ethernet cable assemblies were more than able to withstand the rigors of real world use and extreme conditions. All of the tested cables surpassed performance requirements and flex testing had no significant effect on the cable’s mechanical or electrical performance.
