Two possible applications are shown in
The difference between two-wire and three-wire application is shown in
Gear Tooth Sensing
In the case of ferromagnetic toothed wheel application the IC has to be biased by the
south or north pole of a permanent magnet (e.g. SmCO
with the dimensions 8 mm × 5 mm × 3 mm) which should cover both Hall probes.
The maximum air gap depends on:

– the magnetic field strength (magnet used; pre-induction) and
– the toothed wheel that is used (dimensions, material, etc.; resulting differential field)
