HALL EFFECT SENSOR
Chapter Issue 1 Sep 02 Technical Reference Manual 20.5
HALL EFFECT SENSOR
Description A Hall effect transducer and magnet are combined in a common package, with
a gap between the transducer and magnet. With power ON and the gap clear,
the output transistor is switched on and the signal voltage is pulled down to 0V.
When a ferrous vane is passed through the gap, the Hall effect is cancelled,
switching off the output transistor and the signal is 12V via the digital input
circuit.
Figure 20-3 Hall Effect Schematic
Testing/
Adjustment
With Power ON and a voltmeter connected with +ve to signal (green) and -ve
to 0V (black), the following results should be obtained:
