Hello All,

Does anyone have a link or hint regarding shielded CAT-5 which is as

Mainly Ethernet terminations aren't shielded, so there's
no 'ground' connection in the RJ-45 plug. If you go to the
shrounded connectors, the compatible shielded cable is stiff
jacket/foil-shield over (?solid) wires.

Could you ground a braided tube at the chassis and on the
drawer, and just route a stranded CAT5 cable through that?
I have this joy/frustration with people that beat me at thinking
outside of the box.

That's what they have in the system now. It's a pain in the neck in
production (very complex mechanics) and then there is the concern of
chafing.

Adhesively bond the mesh to the jacket. Select the adhesive
carefully.

Production folks don't like that kind of stuff

Anyhow, as posted in my response to Graham we've found a domestic source
that might work:

A lot of engineering is based on finding a solution NOW. Rather than
analyzing everything to death (the academic approach). Let us know
what the results are.

I will. But it's a client so I won't know when they will get around to
this part of the project.

Hello All,

Regular shielded is quite stiff. During EMC we discovered that a cable
inside a unit needs to be shielded and it has to go through a harness that
will be bent back and forth whenever a drawer mechanism opens. Not every
minute or so, just once in a while. It just can't be too stiff.

Try these.

www.lappusa.com
www.igus.com

Both have continuous flex CAT5 cabling.

Thanks for the hints, Jeff. I'll check them out.
