HAL560  
4.2. HAL560  
Applications  
TheHAL560isalowsensitiveunipolarswitchingsensor  
with an inverted output (see Fig. 4–5).  
The HAL560 is designed for applications with one mag-  
neticpolarityandstrongmagneticamplitudesatthesen-  
sor position where an inverted output signal is required  
such as:  
The sensor turns to low current consumption with the  
magnetic south pole on the branded side of the package  
and turns to high current consumption if the magnetic  
field is removed. It does not respond to the magnetic  
north pole on the branded side.  
– applications with strong magnets,  
– solid state switches,  
– contactless solutions to replace micro switches,  
– position and end point detection, and  
– rotating speed measurement.  
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 inverted  
– low sensitivity
