detection initiation range
Channel B
- Signal A is nominally in quadrature to signal B (90° phase shift).
- A = B = High is the indexed position and is outside of the detection range because of
magnetic indexing.
- The signals should not be evaluated until the state A = B = Low is reached.

As driver an ULN2003A with open collector output with integrated clamp diodes
is used. The cathode of all clamp diodes is connected to common and protects
the encoder against, for instance, inductive surges. For this purpose, the com-
mon pin must be connected to U

to which the pull-up or load resistors are also
connected.
