Hall effect sensor question

Hey all,

I'm looking to use a hall effect sensor to measure the rpm of a wheel. The wheel will max out at 3000 rpm. Would a hall effect sensor have the sensitivity to switch on and off 50 times a second? Even better 100 times a second?

Any feedback would be much appreciated.

Thanks,
Marc

    It depends on the sensor. This one from SparkFun has a maximum switching frequency of 10KHz.
