Tolerances Build-up
The following examples incorporate many different factors in order to show how tolerance buildup can
affect a Hall Effect system. Air gap tolerance, temperature range, and the temperature coefficient of the
magnet will cause the activation distance of a US5881 EUA to vary, thus impacting switching accuracy.
Tolerances:
Air gap Tolerance = 3mm. +
1 mm. and 6mm. +

The US5880 Hall-Effect Switch has a maximum BOP of 250 Gauss and a minimum BRP of 140 Gauss.
If this part were to be actuated by sample Magnet B at an air gap of 3mm and 6mm, the following results
would occur (See Graphs 3 and 4). Each graph has an air gap tolerance of +
1mm which could be due to
a loosely fitted mechanical assembly. Notice the difference in distance and slope between Graphs 3 and
4.

Graph 2 shows what
happens to the slope of a
flux density vs. distance
graph by using different air
gaps with the same magnet
configuration.
