SEMICONDUCTORS
DESCRIPTION
The  ZMY20M  is  an  extremely  sensitive  magnetic  sensor
employing the magneto-resistive effect of thin film permalloy.
It allows the measurement of magnetic fields or the detection
of  magnetic  parts.   The  highly  sensitive  and  small  size
magnetoresistivesensorsconsistofchipcoveredwiththinfilm
permalloy stripes. These stripes form a Wheatstone bridge,
whose output voltage is proportional to the magnetic field
component Hy. The required perpendicular field Hx which is
necessary  to  stabilize  sensor  operation,  is  created  by  an
internal permanent magnet.
