The most noticeable difference in these curves, compared
to the parallel results, is the lack of hysteresis switching.
This is due partly to the auxiliary magnet stabilizing the
sensor and the fact that the orientation of the target
magnet means it does not produce a magnetic field in the
x-direction and cannot therefore adversely affect the
sensor.
An interesting feature of these curves is the way the
curvature changes near the ends of the magnet. This slight
flattening and possible reversal of the curve can be seen
more clearly when a single 4

The reason for the change in curvature is that at small
distances from the target magnet, the radial field H

ends of the magnet is stronger than the field required to
induce a maximum response in the sensor. This effectively
saturates the sensor and the output can fall even as H
increases.
A slightly different approach can be used for very high
resolution measurements. Using a compact RES190
magnet with dimensions of 3
back of the sensor rather than directly above it (see
Fig.70), the output of the sensor was plotted for separation
distances of 1 mm, 0.5 mm and 0.1 mm.
Figure 71 clearly shows that this set-up is very well suited
for high resolution or high sensitivity measurement of
position at very short distances, using the linear part of the
response curve.
