4.4. HAL575
The HAL575 is a medium sensitive latching switching
sensor (see Fig. 4–4).
The sensor turns to high current consumption with the
magnetic south pole on the branded side of the package
and turns to low consumption with the magnetic north
pole on the branded side. The current consumption does
not change if the magnetic field is removed. For chang-
ing the current consumption, the opposite magnetic field
polarity must be applied.
For correct functioning in the application, the sensor re-
quires both magnetic polaritys on the branded side of the
package.
Magnetic Features:
– switching type: latching
– medium sensitivity
– typical B
ON
: 4 mT at room temperature
– typical B
OFF
: –4 mT at room temperature
– typical temperature coefficient of magnetic switching
points is 0 ppm/K
– operates with static magnetic fields and dynamic mag-
netic fields up to 10 kHz
Applications
The HAL575 is designed for applications with both mag-
netic polaritys and weak magnetic amplitudes at the
sensor position such as:
– applications with large airgap or weak magnets,
– multipole magnet applications,
– contactless solutions to replace micro switches,
– rotating speed measurement.
