Encoders for 1/2" Output Shaft

So far I've found that the easiest thing to do is to put one earlier in the drivetrain, such as on the face of the CIMs, the gearbox shafts, or the ends of shafts.

EDIT: Why non-optical?

Mounting the encoder directly on the cim output shaft was our first solution, but if you aren't familiar the the Gem 500 gearbox, the way the cim is mounted makes it hard/impossible to effectively space it out to fit the encoder in. I'd also be worried about spacing out the motor because I'm not sure how the shaft would react with the gear at very end of it at stall torque.

The logic behind avoiding optical is that this is for the NASA Robotic Mining Competition and it gets very dusty when mining. So we would be penalized for lack of dust tolerance as well as possibly having problems with the encoders in dusty conditions.
