4.8. HAL509
The HAL509 is a unipolar switching sensor (see
Fig. 4
–
29).
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.
Magnetic Features:
–
switching type: unipolar
–
low sensitivity
–
typical B
ON
: 26.8 mT at room temperature
–
typical B
OFF
: 23.2 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
–
300 ppm/K
Applications
The HAL509 is the optimal sensor for applications with
one magnetic polarity and strong magnetic fields at the
sensor position such as:
–
solid state switches,
–
contactless solution to replace micro switches,
–
position and end point detection, and
–
rotating speed measurement.
