MAGNET SELECTION GUIDE
The below guide is designed to aid in determining the best magnet for use with a Hall-effect or magnetoresistive sensor. There are several
factors to consider when choosing a magnet. The most important is gap distance. There must be a strong enough magnetic Gauss level
to operate the sensor at the correct distance. By using the maximum operate magnetic Gauss characteristics, you can determine which
magnet will operate the sensor. The other important factors include temperature and physical environment of the application. The Gauss
levels below are typical values only and not guaranteed rated specifications.
*Magnet exibits good stability over indicated temperature range
**Gap distance from sensing surface
***Measurement device saturated @ 800 Gauss
†Millitesla = Gauss × 10
