Note: Flux entering to the South Pole of the magnet will operate the
sensor when magnet is positioned as shown in above drawing. This
assumes the convention that the direction of the external flux of a
magnet is from the North to the South Pole of the magnet

Output voltage increases from
Vnull (2.5 V typ.) as South Pole
gets closer to sensor
Output voltage decreases from
Vnull (2.5 V typ.) as North Pole
gets closer to sensor
Note: In the above drawing the magnet field direction is defined as follows:
(+) Positive Gauss represents the South Pole of the magnet facing the
sensing the area
(-) Negative Gauss represents the North Pole of the magnet facing the
sensing the area

Note: Flux entering to the South Pole of the magnet will operate the sensor
when magnet is positioned as shown in the above drawing. This assumes
the convention that the direction of the external flux of a magnet is from
the North to the South Pole of the magnet. Latching devices requires both
South and North Poles in order to ensure sensors operate and release
respectively
