What is a magnetic sensitive diode, its structure, advantages and disadvantages, principles, applications, installation, faults, and solutions 2

2. Disadvantages:

a. Uneven sensitivity: Currently, the magnetic sensitivity effect of conventional materials in magnetic sensitive diodes is non-uniform, resulting in changes in sensitivity at different positions.

b. Large temperature drift: The temperature characteristics of magnetic sensitive diodes are relatively unstable, and they are prone to drift when the temperature changes.diode

3、 Principle:

The working principle of a magnetic sensitive diode is based on the magnetic sensing effect. This effect refers to the corresponding change in the resistance value inside the material when the magnetic induction intensity changes. When a magnetic field acts on a magnetic sensitive diode, the electrons inside the conductor are displaced by the magnetic field force, thereby changing the motion state of the electrons in the conductor. This leads to a change in resistance value, which in turn reflects the strength of the magnetic field.

4、 Application:

Magnetic sensitive diodes are widely used in many applications. Here are some common application areas:diode

1. Circuit protection: Magnetic sensitive diodes can be used to detect overcurrent conditions in circuits to avoid damage caused by the circuit.

2. Magnetometer: Magnetic sensitive diodes can be used to measure the strength and direction of magnetic fields, such as in geomagnetic measurements, navigation systems, etc.diode

3. Position sensor: Magnetic sensitive diodes can be used to detect the position and displacement of objects, and applied to position control and automation systems.diode

4. Non contact switch: Magnetic sensitive diodes can be used as non-contact switches, such as in safety systems, automotive backup switches, etc.diode
