No. According to the data sheet the sensor must be 2.5 to 1 millimeter from the gear, and directly facing it.
The only way to mount to the clear cover and reach the 50 tooth gear at the bottom is to use spacers. I tried 3/4 inch spacers, and that was a little too long. Half-inch spacers may not be enough.
In the end we drilled the aluminum plate and mounted with a few plastic washers. Then it worked great. See the pictures above.
