Proximity Switch
The proximity configuration is the simplest, though it requires the greatest amount of physical movement. It
is also less precise in terms of the position that results in turning the sensor ON and OFF. The magnetic field
intensity is greatest when the magnet is against the branded face of the Hall IC and decreases exponentially as
the magnet is moved away.
Figure 3, Proximity Switch
In Figure 3A, the South magnetic pole is close to the Hall IC, so the switch turns ON. In Figure 3B, the
South magnetic pole has moved too far away, so the switch turns OFF.
