HAL560
4.2. HAL 560
The HAL 560 is a low sensitive unipolar switching sensor
with an inverted output (see Fig. 4–5).
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.
Magnetic Features:
– switching type: unipolar inverted
– low sensitivity
– typical B_ON: 45.6 mT at room temperature
– typical B_OFF: 51.7 mT at room temperature
– operates with static magnetic fields and dynamic mag-
netic fields up to 10 kHz
Applications
The HAL 560 is designed for applications with one mag-
netic polarity and strong magnetic amplitudes at the sen-
sor position where an inverted output signal is required
such as:
– applications with strong magnets,
– solid state switches,
– contactless solutions to replace micro switches,
– position and end point detection, and
– rotating speed measurement.

The hysteresis is the difference between the switching points B_HYS = B_OFF – B_ON
The magnetic offset is the mean value of the switching points B_OFFSET = (B_ON + B_OFF) / 2
Changes to the previous edition:
– tighter specification for B_OFF at –40 °C, 25 °C, and 100 °C
– specification for 140 °C and 170 °C added
