In most cable applications the choice of cable is simple – Screened, Unscreened. Multicore or Multipaired.
Usually cables are fixed and do not move. However, what if your application requires contact movement? When you start to think about it, there are many applications where constant movement is required; from a cable attached to a Robot to a cable in a car wash. There are also many small devices with internal, moving parts that need the cables to be constantly flexing.
So just what makes a Superflex cable and who makes them? A good example of the difference between a normal cable and a Superflex cable is in the makeup of the internal copper stranding. For example, a typical cable @ 0.5mm2 will be made up of 16 strands of thin copper wire x 0.2mm2, whereas a Superflex will have many more thinner strands which vary from manufacturer to manufacturer.
Superflex cables work in a manner which relies on the fact that the thinner strands are less likely to snap during flexing, enabling them to flex up to 1 million times.
Typical Standards:
- Multi-strand according to DIN VDE 0295 class 6, IEC 60228 class 6
- Jacket special PVC according to UL class 43 and VDE 0207 TM5,
- Temperature-resistant according to VDE 0207 up to 90 °C
- Conductors colour-coded according to DIN 47100
