The SS490 Hall Effect Flux: A Comprehensive Guide**
The SS490 Hall Effect Flux is a solid-state electronic device that can measure the strength of a magnetic field. It is based on the Hall effect, a phenomenon that describes the generation of a voltage across a conductor when it is subjected to a magnetic field. The SS490 Hall Effect Flux is a versatile device that can be used in a variety of applications, including:
- Magnetic field sensing
- Current sensing
- Position sensing
- Speed sensing
How Does the SS490 Hall Effect Flux Work?
The SS490 Hall Effect Flux consists of a thin semiconductor wafer with four terminals: two input terminals and two output terminals. When a voltage is applied across the input terminals, a current flows through the wafer. If a magnetic field is present perpendicular to the wafer, it will cause the electrons in the wafer to deflect, creating a voltage across the output terminals.
The strength of the voltage across the output terminals is proportional to the strength of the magnetic field. This makes the SS490 Hall Effect Flux a very sensitive magnetic field sensor.
