Magnetic proximity sensors
These sensors use a Hall effect cell, a magnetoresistive sensor or a REED switch. Each of these sensitive elements sees its electrical properties modified when a magnet (magnetic field) is brought into its vicinity.
Principle
An element sensitive to the amplitude of the magnetic field (Hall cell) or to the direction of the magnetic field (magnetoresistive sensor) sees its electrical properties modified when a magnet is placed in the vicinity of the sensing face.
Principle
An element sensitive to the amplitude of the magnetic field (Hall cell) or to the direction of the magnetic field (magnetoresistive sensor) sees its electrical properties modified when a magnet is placed in the vicinity of the sensing face.
A signal-shaping stage comprising a Schmitt trigger evaluates the amplitude of the signal delivered by the Hall or magnetoresistive cell. Depending on the voltage attenuation measured, it triggers a change in the state of its output which controls the output stage of the sensor.
