Hall Liner Sensor is a magnetic field sensor made according to the Hall effect. The Hall effect is a kind of magnetoelectric effect, which was discovered by Hall (A.H.Hall, 1855-1938) in 1879 when he was studying the conductive mechanism of metals;

Later, it was found that semiconductors and conductive fluids also have this effect, and the Hall effect of semiconductors is much stronger than that of metals. Various Hall elements made of this phenomenon are widely used in industrial automation technology, detection technology and information processing, etc. aspect. The Hall effect is a basic method to study the properties of semiconductor materials;

The Hall coefficient measured by the Hall effect experiment can determine important parameters such as the conductivity type, carrier concentration, and carrier mobility of semiconductor materials.

What are the main types of Hall Liner Sensors?

Switch type

Among them, Bnp is the magnetic induction intensity of the working point "on", and BRP is the magnetic induction intensity of the release point "off". When the applied magnetic induction exceeds the operating point Bnp, the sensor outputs a low level. When the magnetic induction intensity drops below the operating point Bnp, the sensor output level remains unchanged. When the magnetic induction intensity drops to the release point BRP, the sensor changes from a low level. transition to a high level. The hysteresis between Bnp and BRP makes switching more reliable.

Key lock type

When the magnetic induction exceeds the operating point Bnp, the sensor output changes from high level to low level, and after the external magnetic field is withdrawn, its output state remains unchanged (that is, the latch state), and the reverse magnetic induction must be applied to reach BRP. , to change the level.

Linear

The output voltage has a linear relationship with the external magnetic field strength, and it has good linearity in the range of magnetic induction intensity from B1 to B2. When the magnetic induction intensity exceeds this range, it will appear in a saturated state.

What is the use value of Hall Liner Sensor?

Hall Liner Sensor is a magnetic field sensor made according to the Hall effect. The Hall effect was originally just a kind of magnetoelectric effect. Later, after research, it was found that semiconductors and conductive fluids can also produce this effect, and the Hall effect of semiconductors is much better than that of ordinary metals. Therefore, researchers have used this phenomenon to make various Hall elements. It is widely used in important aspects such as automation technology, information processing and detection technology of modern industry.
