I am looking at a magnetic pickup sensor datasheet.
This graph shows the output voltage against the surface speed.
However, there are 3 curves, that changes the output voltage range changes.
What could be the meaning of "8P", "10P" and "16P"? Are these the poles of the reluctor?
There are no other information in the datasheet except mechanical drawings.
Edit: I don't have the datasheet file right now, here is the best datasheet I found on google about this sensor... it's the same one except the graph.
