So i have some operator panels that are mission critical that need the rotary encoders changed in. That's easy but there are multiple very basic 10 way, 0.5mm pitch 5.5mm width x 78mm long that feed various switch arrays or displays sections & these are now due to age de-laminating & cannot be reinstalled.
It's impossible to hard wire, the manufacturer has classed the equipment as No Longer Serviceable (so no spares).
These were made by Sumitomo who provide a very comprehensive pdf catalog on such tech. I have searched & find various suppliers DigiKey, Mouser etc that do not carry stock. They can contract to manufacture but that means many, many units!
What to do? My only option as i see it is whether anyone may have seen such a flat ribbon flex used elsewhere & in another product? Length is not important. Perhaps it is a current spare part? This is the 1st time such a situation has arisen so things are kind of desperate! Has anyone else had this sort of problem?
