4.6. HAL506
The HAL506 is the most sensitive unipolar switching
sensor of this family (see Fig. 4
–
21).
The output turns low with the magnetic south pole on the
branded side of the package and turns high if the mag-
netic 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 HAL516 is a sensor with the
same magnetic characteristics but with an inverted out-
put characteristic.
Magnetic Features:
–
switching type: unipolar
–
high sensitivity
–
typical B
ON
: 5.5 mT at room temperature
–
typical B
OFF
: 3.5 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 HAL506 is the optimal sensor for all applications
with one magnetic polarity and weak magnetic ampli-
tude at the sensor position 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.
