REFLECTOR: GEMS Optical Sensors

[Dave Philipsen]

Hi Jim,

I ordered one recently.  I got the stainless steel one with 5/8" 
threads.  Since the device only sinks a small amount of current (I'm 
thinking on the order of 20ma) I designed a small relay printed circuit 
board.  The relay has a sensitive coil that can be actuated directly 
from the GEMS sensor.  You then get either NC or NO dry contacts that 
can drive an amp or so.

I've still got the box in the hangar so I'll retrieve it tomorrow and 
let you know the part number.  Works great!
