Hall-Effect Current SensorsOCS Hall-Effect current sensors are a series of analog or digital-analog mixed sensor integrated circuits, They are used to detect the external magnetic field generated by the energized conductor, output voltage signals proportional to the magnetic field strength/current size...
of a magnetic field, a voltage is generated across it. He found that this voltage, now named after him, is proportional to the vector cross product of the current flowing through the sensor and the magnetic field. The proportionality constant γ is a property of the Hall Effect sensor....
A single Allegro Hall-effect sensor IC device can be seen in figure 6. This is the simple switch with functional block diagram as shown in figure 2. All of the circuitry is included on the IC, including the Hall element which can be seen as the red square in the middle o...
Hall effect sensors have been widely used in various linear proximity detection devices to respond to changes in the magnetic field of the proximity device. For example, the detected magnetic pole may be close to the sensor perpendicular to the Hall sensor, or the magnet may pass through the p...
