Sample Magnet A is used in the double-pole slide-by method to show the variation air gap may have in
a mechanical system. These changes in air gap may be caused by factors such as vibration, wear, etc...
Note the differences in each air gaps slope and maximum flux density. As the air gap distance becomes
larger, a decrease in flux density slope will cause less accurate switching in a Hall Effect System.
Graph 9
Graph 6, Slide-by with Sample Magnet A Air Gap Tolerance
By zooming in on the previous graph, min. BRP and max. BOP of the Hall Effect System can be shown
in greater detail and will also reveal the differences in activation distance at each air gap. See Graph 10.
Graph 7, Slide-by with Sample Magnet A
Change in Activation Distance with Air Gap
The plotted lines in Graph 7 do not include the effects of temperature. Graph 8 shows how temperature
will change the magnets flux density characteristics over the selected operating temperature range (-40

to 85

and max. B

. To simplify the graph, only
the 2mm air gap is plotted.
