Hall linear/angular position sensor
A Hall position sensor delivers a signal proportional to the
linear position (displacement) and/or angular position of
a magnet fi xed to a moving part.
The sensor detects either the amplitude or the direction of the magnetic fi eld created by the magnet. The application-specifi c magnetic circuit includes a pole piece that concentrates the field.
