i hope your not trying to use these on a drive train! their avrage life is 15,000 revolutions. our robot has a 1/3 gear ratio to the wheels, and they turn at like 300 rpm. this sensor would wear out in a matter of minutes!

if your going for high presision stuff like, say, an arm, it is *okay* but there are better options. like limit switches? lol jk have fun with this. i just hope you dont use intrupts...
