Hello all,
I was wondering if you could help me identify a part (actually 2 parts) from a rotary encoder. It's a nice, heavy duty dual concentric switch from an old piece of avionics. I'm trying to find out more about its optical components . It has 2 emitters and 2 detectors on each deck, with a nice glass domes. I have no idea if they work in a visible light spectrum or IR, or how to drive them. What's kind of odd about them is - they don't have leads - the whole package goes through a hole in the PCB and the bottom part is soldered on the other side. They are tiny - about 2mm (0.08in) across.
Has anyone seen anything like this before? Or at least any ideas how to (non-destructively) find out its operating voltage?
