May I refer you to someone else's photo?

I believe the item on the right is a IR diode.
I'm not sure what the receiver is or how it works, but while playing with one, trying to make a position sensor out of one, I discovered that it may be photo voltaic. Does any one know for sure how this item works?
My real need is to make a sensor to detect when a shaft has receded to a point so I can energize a coil for .030 seconds to raise it back up and start the process over. This is on a fuel pump that keeps burning up the contacts and a new pump is $140
I would appreciate any help I can get on learning what that device on the left of the photo is and maybe some suggestions on a good sensor for when the shaft is down. I thought about a hall effect device, but when the coil energizes, there's too much flux flowing for a hall effect device. I had some strain gauge devices, but I can't find them, so I think optical would be optimal
Thanks,
Kinarfi
