Am I correct that shielded cable is shielded because of the foil which wraps the cable (underneath the layer of insulation). Then the ground wire will be connected to something on either end to pass the "stray" charges.
Now, I have an application which carries a +5vDC pulse through 22awg wire into a drive. The manual of he drive warns that this line is sensitive to external noise. Frequencies of 100khz will likely be seen by this line.
So I am definitely routing the 16 wires which will be carrying 160vDC as far away as I can from those 5v lines. But, there's only so far I can separate them. At the closest point, they will be 2" apart from eachother. So I was wondering, if I carefully wrapped aluminum foil around the wire, would it shield it? The wire will not be moving, so I don't concern about breakage.
