4.3. HAL566  
Applications  
The HAL566 is a very sensitive unipolar switching  
sensor with an inverted output (see Fig. 4–9).  
The HAL566 is designed for applications with one mag-  
netic polarity and weak magnetic amplitudes at the sen-  
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 large airgap or weak 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.  
In the HAL55x, HAL56x two-wire sensor family, the  
HAL556 is a sensor with the same magnetic character-  
istics but with a normal output characteristic.
