4.3. HAL574
The HAL574 is a medium sensitive unipolar switching
sensor (see Fig. 4–3).
The sensor turns to high current consumption with the
magnetic south pole on the branded side of the package
and turns to low current consumption if the magnetic
field is removed. It does not respond to the magnetic
north pole on the branded side.
For correct functioning in the application, the sensor re-
quires only the magnetic south pole on the branded side
of the package.
In this two-wire sensor family, the HAL584 is a sensor
with the same magnetic characteristics but with an in-
verted output characteristic.
Magnetic Features:
– switching type: unipolar
– medium sensitivity
– typical B
ON
: 9.2 mT at room temperature
– typical B
OFF
: 7.2 mT at room temperature
– typical temperature coefficient of magnetic switching
points is 0 ppm/K
– operates with static magnetic fields and dynamic mag-
netic fields up to 10 kHz
Applications
The HAL574 is designed for applications with one mag-
netic polarity and weak magnetic amplitudes at the sen-
sor position such as:
– applications with large airgap or weak magnets,
– solid state switches,
– contactless solutions to replace micro switches,
– position and end point detection, and
– rotating speed measurement.
