Looking for a very good photoreflector? The OPB730F is an EXCELLENT unit!
The OPB730F is a really nice reflective sensor in a TO-72 package, with a reflection sensitivity peaking at about 0.1", but is quite useful out to the 1" range. It uses a gallium arsenide IR LED and a NPN silicon darlington (that means it's extra sensitive) phototransistor pickup in a side-by-side arrangement, and have ambient-light filtering built-in.
These sensors usually go for over $10 in lots of 50+. This is an incredible special!
