I have an old set of Sargon linear glass encoders. I've verified that the glass is still in one piece (By eye), and I have the read head. The part with the LED and photo sensor.
I don't know if I get quadrature sine waves or just quadrature square wave off the detectors. But I need the physical part of the read head that relieves strain for the cable and holds the detectors around the glass.
It'd be easier to just buy new read heads instead of starting yet another development project. But I can't seem to find anyone who sells individual read heads. Can anyone give me any pointers to vendors?
Also if this is the wrong forum sorry.
