4.2. HAL502
The HAL502 is the most sensitive latching sensor of this
family (see Fig. 4
–
5).
The output turns low with the magnetic south pole on the
branded side of the package and turns high with the
magnetic north pole on the branded side. The output
does not change if the magnetic field is removed. For
changing the output state, the opposite magnetic field
polarity must be applied.
For correct functioning in the application, the sensor re-
quires both magnetic polarities (north and south) on the
branded side of the package.
Magnetic Features:
–
switching type: latching
–
high sensitivity
–
typical B
ON
: 2.6 mT at room temperature
–
typical B
OFF
:
–
2.6 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 HAL502 is the optimal sensor for all applications
with alternating magnetic signals and weak magnetic
amplitude at the sensor position such as:
–
applications with large airgap or weak magnets,
–
rotating speed measurement,
–
commutation of brushless DC motors,
–
CAM shaft sensors, and
–
magnetic encoders.
