OT: Photoeye

Where can I find a simple "photoeye" device that works by shining on a reflector and simply operates a relay when the beam is interrupted?

All I can find is expensive stuff that runs a ding-dong "annunciator".

I could cut that up, but would just as soon not.

Thanks! ...Jim Thompson

Look for industrical photoelectric sensors. They're commonly used on production line to count boxes on a conveyor belt, safety shutdown, etc.

Sorry for the delay in this answer. I just got back to newsgroups after many years away. Would this work for you?
