Linear Hall sensors  are mainly used for the measurement of some physical quantities. 1. Current sensor: Because there is a magnetic field inside the energized solenoid, its size is proportional to the current in the conductor, so the Hall sensor can be used to measure the magnetic field to determine the current in the conductor. Using this principle, a Hall current sensor can be designed. The advantage is that it does not make electrical contact with the circuit under test, does not affect the circuit under test, does not consume the power of the measured power supply, and is particularly suitable for large current sensing. 2. Displacement measurement: The two permanent magnets are placed opposite to each other, and the linear Hall sensor is placed in the middle. The magnetic induction intensity is zero. This point can be used as the zero point of the displacement. When the Hall sensor is used to make a △Z displacement on the Z axis, the sensor has A voltage output, t...

According to the nature of the detected objects, applications of  Hall Sensor  can be divided into: direct application and indirect application. The former is to directly detect the magnetic field or magnetic property of the object under test, and the latter is to detect the magnetic field set by the object under inspection, and use this magnetic field as a carrier of the detected information, through which many non-electrical, non-magnetic The physical quantity. Forces, moments, pressures, stresses, positions, displacements, speeds, accelerations, angles, angular velocities, revolutions, rotation speeds, and times when the operating conditions change, for example, are converted into electrical quantities for detection and control.

Hall sensors are widely used in our daily lives. For example, in a mobile phone with a flip cover or a slide cover, a device for detecting opening or sliding of the mobile phone cover is a Hall sensor; for example, on a computer keyboard, a scroll key for moving a cursor is a Hall sensor. Also, there are Hall sensor applications in parts that require motors, such as automotive gearboxes, power windows and doors. We are dealing with Hall sensors in everyday life.  Hall effect sensor circuit  is widely used. Hall sensor applications have different fields, so the requirements of each market are not the same. The main requirements for Hall sensors in the mobile phone market include size, power consumption and adjustable thresholds. For industrial and automotive applications, Hall sensors must first meet industry or automotive certification requirements for devices such as safety, stability, and temperature ranges to achieve corresponding levels.

As many people know, the higher the degree of automation in cars, the more microelectronic circuits are, and the more they are afraid of electromagnetic interference. In the car, there are many lamps and electrical devices, especially the headlights with large power, air conditioning motors and wiper motor will generate inrush current during switching, causing arcing of the mechanical switch contacts, resulting in greater electromagnetic interference signal. Using power  Hall IC  switching circuits can reduce these phenomena. For example, position, displacement, angle, angular velocity, rotation speed, etc., and these variables can be transformed twice; pressure, mass, liquid level, flow rate, flow, etc. can be measured. The current Hall devices can withstand a certain degree of vibration, and can work in the range of minus 40°C to minus 150°C. All the seals are not contaminated by water and oil and can fully adapt to the harsh working environment of automobiles. Ha...

Hall sensor main characteristic parameters are the following types. (1) Input resistance R (2) Output resistance R It also changes with temperature changes. Selecting the appropriate load resistance is easy to match, which minimizes temperature-induced drift in the hydrodynamic potential. (3) Maximum excitation current I - Hall sensor parameters (4) Sensitivity K Sensitivity KH=EH/IB, its value is about 10MV (MA.T). (5) Maximum Magnetic Intensity BM---Hall Sensor Parameters When the magnetic induction intensity exceeds BM, the nonlinear error of the Hall sensor potential will increase significantly, and the Tesla(T) becomes several thousand Gauss (Gs) (1Gs=104T). (6) Equal potentials At rated excitation current F, when the applied magnetic field is zero, it is an error due to the asymmetry of the geometry of the 4 positive poles. (7) Hall sensor temperature ratio We are manufacturer of  Bipolar Hall IC  and  Linear Hall IC . Welcome create busines...

The magnetic encoder adopts the Hall principle and utilizes the magnetic detection method. The magnetic sensor probe converts the changing magnetic field signal into a change of resistance value through the magnetoresistance effect. Under the action of the applied potential, the changed resistance value is converted into a voltage. Change, through the subsequent signal processing circuit processing, the analog voltage signal into a computer can identify the digital signal, to achieve the magnetic rotary encoder encoding function. We supply  Hall Effect technology , supplying  low cost hall effect sensor . Any questions welcome contact to us at any time.

The car odometer can display the mileage of the car, which is based on the number of rotations of the wheels to indirectly derive the mileage. The number of wheel revolutions can be measured with a  Hall sensor , which is an important part of the odometer. Its performance plays an extremely important role in the work of the whole circuit. The magnet is attached to the iron and fixed at a certain position on the wheel. The Hall circuit is fixed on the frame. For each revolution of the wheel, the magnet passes through the Hall IC once and generates a pulse signal, and the counter counts the pulse. Hall sensors commonly used in odometers are mostly  bipolar latch Hall switch .
