4.7. HAL508
The HAL508 is a unipolar switching sensor (see
Fig. 4
–
25).
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 HAL518 is a sensor with the
same magnetic characteristics but with an inverted out-
put characteristic.
Magnetic Features:
–
switching type: unipolar
–
medium sensitivity
–
typical B
ON
: 18 mT at room temperature
–
typical B
OFF
: 16 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 HAL508 is the optimal sensor for applications with
one magnetic polarity such as:
–
solid state switches,
–
contactless solution to replace micro switches,
–
position and end point detection, and
–
rotating speed measurement.
