"Hall Sensor" of the American Honeywell Brand

The Hall sensor is a magnetic field sensor made according to the Hall effect. The Hall effect is a kind of magnetoelectric effect. This phenomenon was discovered by Hall in 1879 when he was studying the conductive mechanism of metals. Later, it was discovered that semiconductors and conductive fluids also have this effect. The Hall effect of semiconductors is better than that of metals. It is much stronger. Various Hall elements made using this phenomenon are widely used in industrial automation technology, detection technology and information processing.
Honeywell is the first company to develop Hall-effect technology products. For more than 30 years, the company has been keeping up with changes in industrial demand, developing different types of Hall-effect technology products to meet the needs of different fields, and constantly improving product performance. Honeywell's advanced product technology makes it a global leader in the control field.
The magnetic position sensor produced by Honeywell is compact and adopts an ultra-small SOT-23 surface mount package; the operating voltage can be as low as 2.7 V, which reduces current and improves energy efficiency; built-in pull-up resistors , Can simplify the connection; built-in reverse voltage protection function, fully protect the integrated circuit from damage during assembly; high resistance design can adapt to the working environment of up to 150 degrees Celsius.
Application of Hall sensor in brushless DC motor
The torque in a DC motor is generated by the interaction between the magnetic field of the permanent magnet and the current in the winding. In a brushed motor, the commutator realizes the commutation of the armature current and a suitable magnetic field by switching the armature winding. In the brushless DC motor, the Hall position sensor detects the position of the rotating magnetic field of the rotor, and the corresponding winding is excited through the logic and drive circuit. In general, the windings react to the magnetic field of the permanent magnets of the motor to produce the required torque.

Main components of brushless DC motor
The user can make a reasonable choice according to the installation requirements (that is, the direction of the rotor magnetic field) and the sensing direction of the Hall sensor. Honeywell's SS30, SS31x/SS41x and SS36x/SS46x series of Hall-effect sensors can provide the precise motor shaft position data required for brushless DC motors.

Application of SS461C Hall Effect Sensor in Automobile
With the development of electronic technology, the degree of electronization of automobiles is getting higher and higher. A good car control system can improve the adhesion between the wheels and the ground, thereby improving the safety, power and comfort of the car. The sensor is the core device in electronic technology and a device for signal conversion. Its function is to convert the measured non-electricity signal into an electric quantity signal. It is a key device to promote the overall development of automobile technology. In the automobile chassis electronic control system, the control work is inseparable from the sensor, and the speed sensor plays a major role in the automobile control system.
