By orienting a sensor’s axis to 45 with respect to the axis
of the permanent magnet, as shown in Fig.58, it is possible
to use the sensor along with a comparator, as a proximity
switch. In this arrangement the sensor has a negative
output, for both axial arrangements of the magnet, which
can then be passed onto the inverting input of a
comparator.
The resulting output is clearly indicative of the distance ‘d’
between the magnet and the sensor (see Fig.59). Sensor
switching levels are very important in this application;
below a certain level, strong external magnetic fields may
disturb the sensor sufficiently to produce ambiguous
results.

Besides being used for general position sensing and
measurement, by incorporating a back biasing magnet,
single-point measurements are possible using any
non-symmetrical region of material within the target such
as a hole, pin, or region of non-magnetic material
integrated into a metal plate’s structure. The resulting
disturbance in the magnetic field produces a variation in
sensor output. Figure 60 shows the basic set-up and at the
crossover point, where the hole and sensor match
precisely, the sensor output is clearly independent of
separation distance.
