ZMY20MTC

P1-P3P4-P4
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.
