So I’m working on repairing a few dental intra-oral x-ray sensors. Some sensors i have discovered have a proprietary cable that the manufacturer wants kept secret and not readily available. I’ve called a few wire manufacturers and distributors and am coming up empty handed…
One particular cable has an outside jacket of 3.4mm and contains 10 conductors. Each conductor is approx 0.67 mm. To add to the complexity, the wires are wrapped in a braided metal shielding and the outside jacket of has a silicone type feel and appearance.
The wires are used in dental offices and are subjected to harsh disinfecting chemicals such as cavicide.
Im attaching a pic of one of the wires and what it looks like.

Would you have any idea where I can find such a “proprietary” cable?
With just a quick glance, I didn’t find the direct equivalent of the cable you have there but there are suitable alternatives. The company I work for routinely buys from Alpha Wire and they make shielded harsh environment cables. Take a look at their Xtra-Guard 5 series of cables with FEP insulation. The jacket is chemical resistant and tolerates temperatures up to 200°C which should work fine with an autoclave.

Funny u said that… I called and spoke with Hector at Alpha Wire yesterday… Yes they make many cables and it seemed like they would be the best choice… Unfortunately the wire they have with 10 conductors is 7.6 mm and that’s way too thick… I need to somewhere between 3 and 4 mm when it’s all done…
I’ve been doing some additional hunting and found cable that’s even smaller than what you are looking for but I haven’t found the specific size you have. Check out http://www.micronmeters.com/c-190-miniature-cable.aspx . There are a number of options there including various insulation types and number of conductors. The options with the best temperature performance and chemical resistance are in the 2.53mm range with 12 32AWG conductors. Other insulations will get you 10 conductors at 3.05mm or 12 conductors at 3.20mm.
All of it looks like a pain to strip properly!
