4.9. HAL516
The HAL516 is the most sensitive unipolar switching
sensor with an inverted output of this family (see
Fig. 4
–
33).
The output turns high with the magnetic south pole on
the branded side of the package and turns low if the
magnetic field is removed. The sensor 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 the HAL5xx family, the HAL506 is a sensor with the
same magnetic characteristics but with a normal output
characteristic.
Magnetic Features:
–
switching type: unipolar inverted
–
high sensitivity
–
typical B
ON
: 3.5 mT at room temperature
–
typical B
OFF
: 5.5 mT at room temperature
–
operates with static magnetic fields and dynamic mag-
netic fields up to 10 kHz
–
typical temperature coefficient of magnetic switching
points is
–
1000 ppm/K
Applications
The HAL516 is the optimal sensor for all applications
with one magnetic polarity and weak magnetic ampli-
tude at the sensor position where an inverted output sig-
nal is required such as:
–
applications with large airgap or weak magnets,
–
solid state switches,
–
contactless solution to replace micro switches,
–
position and end point detection, and
–
rotating speed measurement.
