Technician A says that the Hall Effect sensor produces a digital square wave voltage signal. Technician B says that the Hall Effect sensor contains a permanent magnet on the outside of the rotating blades. Who is correct?
A) A only
B) B only
C) both A and B
D) neither A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because the Hall Effect sensor does indeed produce a digital square wave voltage signal as it detects changes in the magnetic field when the teeth of a rotating component pass by it. Technician B is incorrect because the Hall Effect sensor does not contain a permanent magnet on the outside of rotating blades; instead, it typically uses a magnet to create a magnetic field which is then modulated by the passing of ferrous objects, altering the voltage signal.
