Hi, everybody! I have these Sharp photointerruptors, GP1A50HR. I'm trying to get them to work, but the schematics in the data sheet have two conflicting pinouts. I've wired the emitter with 5v and a 1k resistor, and I can see IR with the camera on my phone. I tried to power the detector side with 5v, according to both pinouts in turn, but I can't read a change in either current or voltage on pin 4 when I put a piece of cardboard into the slot. I think I might have fried it with the reverse voltage, though. Is there anyone who has worked with these?
