Not side by side-
In the placement described we are talking about them facing each other= with=20 a gap between the faces of 0.100~0.125 and the wheel face between them like= an=20 interrupter between optical sense and receive.

Highly unlikely. I have friends who measure integ= rity of=20 signal with oscilloscope. Shielded device with highly directional sensiti= vity.=20 Though they've never measured two side by side. Good theory, though.=20

There is nothin= g wrong=20 with that idea. The only concern is that the two sensors may have=20 interference with each other. The idea is to put another toothed wheel= =20 rotated say a random 33.715= degrees=20 relative to the first wheel. Now you place the second sensor rotated th= e=20 same 33.7....etc degrees. So now when you switch sensors the timing is = the=20 same. Also the two sensors don't interfere with each other.
