KMT32B Datasheet, PDF (3/7 Pages) List of Unclassifed Manufacturers – MAGNETIC ANGLE SENSOR

MAGNETIC ANGLE SENSOR
KMT32B
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.
