    Hi,
    I am using the following ribbon cable

    http://www.digikey.com/scripts/DKSearch/dksus.dll?Detail&itemSeq=134642068&uq=635115531978263892

    Datasheet:
    http://multimedia.3m.com/mws/mediawebserver?6666660Zjcf6lVs6EVs666UEjCOrrrrQ-


    I am intending to submit this cable attached to my device for UL testing. The datasheet says that this cable can stand up to 30 Volts DC. I do not know how UL will test this cable and with how much voltage.

    This cable will also have following connectors on its two ends

    1. http://www.digikey.com/scripts/DKSearch/dksus.dll?Detail&itemSeq=134611514&uq=635115545712728205

    2. http://www.digikey.com/scripts/DKSearch/dksus.dll?Detail&itemSeq=133574094&uq=635115545712728205

    My Question:

    Can this cable withstand the testing? or is it appropiate choice? I looked around but was not able to find any cable with these specifications that can tolerate really hiigh voltages. Any recommendations

    The voltages that I am using this cable for are in micro to millivolts range. I do not know how much voltage UL will test this cable for.

  3. Those old multi-colored, twisted pair type ribbon cables IBM and folks
    made used higher dielectric insulation. Some ScSI cables were even cloth
    overwrapped. Some really nice stuff was around back then. still is, but
    it isn't cheap.

    but some is, actually.

    The ribbon cable will not be internal. One end will be connected to the printed ciruit board and the other end will be outside the box, hanging free. The part of the ribbon cable inside the box will have following connector on it

    Digikey part number: S9165-ND

    And the part that stays outside will have following connector on it
    Digikey part number : A32569-ND

  5. If its less than 40v (I think) and 60W then they are not concerned
    with it.

    Cheers

    What does this have to do with high voltage, per your original
    posting?

    Where is the voltage you are worried about? You're allowed 42V in
    energy-limited circuits.

    Does this thing plug into the wall, even?
