Re: High speed encoder with slotted / flat end... can't find one.

Are you using 4x sampling to get the max from your Bourns?
The quoted CPR is based on using only one of the following:
1) rising edge A
2) falling edge A
3) rising edge B
4) falling edge B
Counting each and every one of them gives you 512 ticks per revolution with a "128cpr" encoder.
