Any suggestions as to a sensor with more than a few mm of range?
With a MR-sensor bridge...
With a 6-bit interpolator, like the iC-NV, you will get 64 pulses per rotation...
MR-sensor bridge?
I only need ONE pulse per rotation.
Your RPM is too fast, you may use a magnetic reed switch for your disc, as hall sensor has small sensing range
If you drill a hole through the shaft, light could shine through the hole 2 times per revolution.
Devide that signel.
...Another option would be just a photo switch like the iC-LQNP ...
