4.2. HAL560
Applications
TheHAL560isalowsensitiveunipolarswitchingsensor
with an inverted output (see Fig. 4–5).
The HAL560 is designed for applications with one mag-
neticpolarityandstrongmagneticamplitudesatthesen-
sor position where an inverted output signal is required
such as:
The sensor turns to low current consumption with the
magnetic south pole on the branded side of the package
and turns to high current consumption if the magnetic
field is removed. It does not respond to the magnetic
north pole on the branded side.
– applications with strong magnets,
– solid state switches,
– contactless solutions to replace micro switches,
– position and end point detection, and
– rotating speed measurement.
For correct functioning in the application, the sensor re-
quires only the magnetic south pole on the branded side
of the package.
Magnetic Features:
Current consumption
– switching type: unipolar inverted
– low sensitivity
