United States Honeywell brand "Hall Sensor"

Hall sensor is a magnetic field sensor made according to the Hall effect. Hall effect is a kind of magnetoelectric effect, this phenomenon was discovered by Hall in 1879 when studying the conductive mechanism of metals, and later found that semiconductors, conductive fluids, etc. also have this effect, and the Hall effect of semiconductors is much stronger than that of metals, and various Hall elements made of this phenomenon are widely used in industrial automation technology, detection technology and information processing.

Honeywell was the first company to develop Hall-effect technology products. For more than 30 years, the company has been keeping up with the changing needs of industry, developing different models of Hall-effect technology products to meet the needs of different fields and continuously improve product performance. Honeywell's advanced product technology positions it as a global leader in control.

Honeywell's magnetic position sensors are compact and available in an ultra-small SOT-23 surface-mount package; The operating voltage can be as low as 2.7 V, which reduces the current and improves the energy efficiency. Built-in pull-up resistor simplifies connection; Built-in reverse voltage protection function to fully protect the integrated circuit from damage during assembly; The highly resistant design can withstand working environments with temperatures up to 150 degrees Celsius.

Application of Hall sensors in brushless DC motors

In a DC motor, the torque is generated by the interaction between the magnetic field of the permanent magnet and the current in the winding, and in the brush motor, the commutator realizes the commutation of the armature current and the appropriate magnetic field by switching the armature winding. In brushless DC motors, Hall position sensors detect the position of the rotor rotating magnetic field and excite the corresponding windings through logic and drive circuits. In general, the windings react to the magnetic field of the permanent magnets of the motor to generate the required torque.

The brushless DC motor is mainly composed of

The user can make a reasonable choice according to the installation requirements (i.e., 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 provide the precise motor shaft position data required for brushless DC motors.

SS461C Hall-effect sensor in automotive applications

With the development of electronic technology, the degree of electrification of automobiles is also increasing. A good vehicle control system improves the adhesion between the wheels and the ground, which in turn improves the safety, dynamics and comfort of the car. The sensor is the core device in electronic technology, a device for signal conversion, and its role is to convert the measured non-electric signal into an electric signal, which is a key device to promote the comprehensive development of automotive technology. In the automotive chassis electronic control system, the control work is inseparable from the sensor, and the speed sensor plays a major role in the vehicle control system.

SS461C Hall-effect sensor in automotive applications

The SS461C Hall Effect Sensor is used in speed sensors to detect the rotation of the crankshaft of a car or truck. The SS461C Hall-effect sensor meets the requirements of high accuracy and uses a digital current sink output to provide high output current and high-speed response.
