4.3. HAL566
The HAL566 is a very sensitive unipolar switching
sensor with an inverted output (see Fig. 4–9).
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.
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.
Magnetic Features:
– switching type: unipolar inverted
– high sensitivity
– typical B
ON
: 4 mT at room temperature
– typical B
OFF
: 5.9 mT at room temperature
– operates with static magnetic fields and dynamic mag-
netic fields up to 10 kHz
Applications
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:
– 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.
