Ribbon Cable and High Voltages

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.

You don't actually say what voltage you're designing for.

If you build a product, and you get it all UL tested, and it burns
someone's house down, then when things go to court the fact that it uses
cabling with higher-than-rated voltage on it will outweigh the fact that
it happened to pass UL testing.

Why don't you want to use cabling that's rated for your use?


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.

300 volt rating and 105°C
 
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

They won't disassemble the product and test the ribbon cables. They
probably will look at the schematic and see if there might be a fire
or safety hazard, which there won't be in your case.

I've taken several products through UL/CE lately, with ribbon cable
jumpers all over the place. Some carry power between boards, and
signals in the 40 volt range. Not a peep.

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

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?
