DMX connector shielding
« on: September 16, 2013, 03:37:17 pm »

I recently made 40 some DMX 5 pin cables and did not put heat shrink over the cups on the connectors i am now being told that i need to redo all of the cables before they will use them i am looking for some backing to the fact that i have tested all of the connectors and they all pass signal and the fact that it is data and not power being sent down the lines.

Doesn't matter what we say, only what your boss says. Unfortunately.

You rarely see heat shrink over the cups on XLR connectors unless the wire size makes the spacing extremely close. At least in my experience this is true. Others may have different experiences.

In mil-spec work seeing Hellerman sleeves is common*.  I suppose a properly specified heat shrink would do the job:  providing mechanical support to the wire, helping to prevent vibration-caused flexing of the conductor and eventual failure.

*at least back in the old days, when I salvaged military electronics for my component bin....

No doubt, Tim, but I can't think of a commercially-made cable that uses anything over the pins now.
The newer XLR's have better strain reliefs, and I doubt I would ever use them now. I wired several hundred mil-spec circular connectors back in the day (37-60+ pins) and put heat shrink over every damn one, but the body had enough space (barely) to do this. I do NOT miss those days.
