Hall Effect Sensor Manufacturer

Hall Effect Sensor Manufacturer
AH3662 Hall Effect Sensor is an Omnipolar micro-power high sensitivity Hall effect sensor, special designed circuit make it owns omnipolar(regardless S pole or N pole) magnetic field excitation function, excellent symmetry of the positive and negative magnetic switch, and very small average current consumption characteristics.  
When the magnet(regardless S pole or N pole)  is closed to sensor（︱B︱≥︱Bop︱），the sensor outputs low level; When the magnet is far away with the sensor（︱B︱≤︱Brp︱）, the sensor outputs high level. Stable hysteresis （Bhx =︱Bopx--Brpx︱）enables the sensors stable switch state. The sensors' magnetic and electric transfer characteristic curve is shown as the figure: 
Micropowr designing；
Rated working voltage 2.4V ~ 5.5V,
Work under Omnipolar, the excitation field regardless of N or S pole, high magnetic sensitivity, highly symmetric of positive and negative magnetic switching points;
Built-in dynamic offset voltage compensation circuit, high temperature stability, small drift switching point, resistance to mechanical stress and thermal stress;
Ultra small power consumption, it’s only 8μW when the power supply is 2.75V

Method Of Detecting Switch Type Hall Sensor

图片
In the use of hall sensor for maintenance machinery, we will encounter holzer not working, from holzer's shape can not distinguish whether the holzer element is damaged, and how to detect whether the switch type of hall sensor is damaged. Taking Holzer YS282 as an example, the test method of switch type Holzer element is as follows: First, find a resistance R of 1K Omega, which is connected to the figure 1 and 3 feet, and connect the positive pole of the DC power of the 12V to the foot of the  switch type hall sensor YS282, and the anode is connected to the foot. The multimeter is placed in a DC 50V file, the red pen is connected to the foot, and the black pen is connected to the foot, and the pointer changes of the multimeter are observed. When the magnet N is very close to the test point of the hall sensor YS282, the pointer of the multimeter is deflected from the high level to the low level; when the N pole of the magnet is far away from the test point of the Holzer...

Application of Linear Hall Sensor

图片
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...
