MAGNET SELECTION GUIDE
This guide is designed to aid in determin-
ing the best magnet for use with a Hall
effect sensor. There are several factors to
consider when choosing a magnet. The
most important is gap distances. There
must be adequate magnetic gauss to op-
erate the sensor at the correct distance.
By using the maximum operate magnetic
gauss characteristics (see sensor order
guides), you can determine which mag-
net(s) will operate the sensor. Other im-
portant factors include temperature
range and the physical environment of
the application.
