When multiple shielded wires pass through a common connector ... Does each shield need its own separate pin or can several shields be ganged together in a single pin? Shields eventually come together at a common ground point someplace, right? 



Thanks,

Jay

Cool! It's been a while since I read over all the neat tricks and tips. 



Another simple question...



Audio wire drawings show shield ground at intercomm (real ground), but open circle at the end-point (i.e. shield pulled back and covered with heat shrink). This one I get.



Other schematics (ADS600B) show shield grounds at both ends of the wire. Really? It would seem unwise to physically ground both sides, so maybe I'm not understanding the intent.



Thanks,

Jay

    Follow the instructions. Shields can be shield-only,

    attach one end; or shield+purposful conductor, attach

    both ends as prescribed.



    Check out extensive discussions on shields on

    aeroelectric.com and in the archives of this

    forum.

I contacted the vendor and they stated that the diagram that showed shield grounds on both ends was a typo. One end only. Glad I asked the question though as there's always more to learn!

Cheers,

Jay

    Any day you go to bed knowing something you did not

    know that morning is a GOOD day. Any day you can

    tap the sum of your knowledge and experience to

    make the life of somebody else easier, it's a GREAT

    day.
