4. Type Description
4.1. HAL501
The HAL501 is the most sensitive sensor of this family
with bipolar switching behavior (see Fig. 4
–
1).
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
state is not defined for all sensors if the magnetic field is
removed again. Some sensors will change the output
state and some sensors will not.
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: bipolar
–
very high sensitivity
–
typical B
ON
: 0.5 mT at room temperature
–
typical B
OFF
:
–
0.7 mT at room temperature
–
operates with static magnetic fields and dynamic mag-
netic fields up to 10 kHz
Applications
The HAL501 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,
–
CAM shaft sensors, and
–
magnetic encoders.
