?SPAN class="pst BU52040HFV-TR_2601631_6">Magnet Selection
Horizontally Stacked Magnet
Vertically Stacked Magnet
Because the field loop in horizontally stacked magnets extends for a shorter distance than that of vertically stacked magnets,
the gap between the magnet and the hall IC must be decreased. Therefore, if horizontally-stacked magnets are used in the
application, the thickness of the magnet or the area of each section should be increased to allow for a larger gap between
the magnet and IC.
Because the IC is unable to detect rotation direction if using magnets that are smaller than the ICs package size, ensure that
the physical size of each N/S division is larger than the ICs package, and that the ICs are properly mounted with an angular
distance of either ?4 or 睛 from one another (where ?= N/S division angle of circular magnet).
