Hi again.  I am looking for an optical sensor, probably LED based,
maybe laser diode, that can be mounted on a thin PCB.  It needs to be
fairly small.  I am designing a small retroreflective system from
inside a slot machined into a molding with a piece of reflective tape
approx 3 ft away.

Usually, with that kind of distance, one uses a modulated
light source and tuned detector: 40 kHz infrared
diodes and integrated circuit receivers for this purpose
are the mainstays of TV remote controls...
