It is a sensor that is sensitive to permanent magnets. When the S pole is close, it is normally open and normally closed, and normally closed. When the magnet leaves, it is normally open and normally closed. When the S pole is close, the self-locking type is turned on and held, and the switch is turned off when the N pole is close.
Switch Hall sensors consist of regulators, Hall elements, differential amplifiers, and Schmitt trigger output stages, which output digital quantities.
Principle Introduction When a current-carrying metal or semiconductor sheet is placed vertically in a magnetic field, potential differences occur across the sheet. This phenomenon is known as the Hall effect. The potential difference between the two ends is called the Hall potential U, and its expression is U=K·I·B/d where K is the Hall coefficient, I is the passing current in the slice, and B is the applied magnetic field (Lorentz Lorrentz) magnetic induction, d is the thickness of the sheet. It can be seen that the sensitivity of the Hall effect is directly proportional to the magnetic induction intensity of the applied magnetic field. The Hall switch belongs to this type of active magnetoelectric conversion device. It is based on the Hall effect principle and is manufactured using an integrated package and assembly process. It can easily convert a magnetic input signal into an electrical signal in a practical application. At the same time, it has the requirements of practical application and easy operation and reliability in the industrial field. The input of the Hall switch is characterized by the magnetic induction B. When the B value reaches a certain level (such as B1), the internal switch of the Hall switch is turned over, and the state of the output level of the Hall switch is also reversed. Transistor output is generally used at the output end, and proximity switches are similar to NPN, PNP, normally open, normally closed, latched (bipolar), dual signal output points.
Hall switches can be applied to proximity switches, pressure switches, odometers, etc. as a new type of electrical accessories. The Hall switch functions like a reed switch magnetron, but it has a longer life than it does, and it responds quickly to wear. Also, the polarity of the magnet must be taken into consideration during installation. The polarity of the magnet does not work.
