Last update 19.01.07
The
KMT32B
magnetic
field
sensor is suited for high precision
angle measurement applications
under
low
field
conditions
(regularly H0 = 25 kA/m, with
reduced
accuracy
applicable
down to H0 = 8 kA/m; beware of
earth’s magnetic field !).

Stress above one or more of the limiting values may cause permanent damage to the device. Exposure to limiting values for
extended periods may affect device reliability.
