5.4 Function and application
Principle of operation
The product determines the position of a sensor magnet via a row of 2 sensor ele-
ments in the sensor head.
The sensor elements measure the field strength in x-direction and y-direction re-
spectively, which allows axially and diametrically magnetized magnets to be de-
tected.
