Feature Description (continued)
Magnetic flux that travels from the bottom to the top of the package is considered positive in this data sheet. This
condition exists when a south magnetic pole is near the top of the package. Magnetic flux that travels from the
top to the bottom of the package results in negative millitesla values.

8.3.2.1 Magnetic Threshold
Devices that have a lower magnetic threshold detect magnets at a farther distance. Higher thresholds generally
require a closer distance or larger magnet.
8.3.2.2 Magnetic Response
Omnipolar devices respond the same to north and south poles as shown in Figure 9.
