Have a try with that RS opto if you can, it's cheap and should work

Have ordered two plus two different reflectives to try (219-2634 is
Omron SY410 and 455-0969 is Optek OPB760T)
I wish I had a fast digital scope with advanced triggering, maybe
then
I could figure out what is happening :(
Sadly I'm still in the Tek 465B (100 MHz) era - thought it was "the
last word" when I bought it - is still working though and very
reliable delayed triggering off a level if repetition rate is high
enough to actually see the trace!
