2. Code repeats every 4 positions

3. Channel A Leads Channel B in CW direction

1. 24 PPR/24 detents is shown

2. The nominal detent position is located

when both Channel A and B are low

3. Channel A Leads Channel B in CW

direction and lags in CCW direction

* It can work well if application circuit still adopts external pull-up

resistors (2.2KΩ).
