4.12. HAL519
The HAL519 is a very sensitive unipolar switching sen-
sor with an inverted output sensitive only to the magnetic
north polarity. (see Fig. 4
–
45).
The output turns high with the magnetic north pole on the
branded side of the package and turns low if the magnet-
ic field is removed. The sensor does not respond to the
magnetic south pole on the branded side, the output re-
mains low. For correct functioning in the application, the
sensor requires only the magnetic north pole on the
branded side of the package.
Magnetic Features:
–
switching type: unipolar inverted, north sensitive
–
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 HAL519 is the optimal sensor for all applications
with the north magnetic polarity and weak magnetic am-
plitude at the sensor position where an inverted output
signal is required such as:
–
solid state switches,
–
contactless solution to replace micro switches,
–
position and end point detection, and
–
rotating speed measurement.
