The colored area in the chart above shows the region of allow-
able air gap movement within which the sensor will continue
output switching. The output duty cycle is wholly dependent on
the target’s magnetic signature across the air gap range of move-
ment, and may not always be within specification throughout the
entire operating region (to AG
