ZS-02 Hall Speed SensorDetailed product description：

One Introduction
The ZS-02 Hall speed sensor adopts the Hall effect. When the metal teeth pass through the front end of the Hall sensor, it causes a change in the magnetic field. The Hall element detects the change in the magnetic field and converts it into an alternating electrical signal. The built-in circuit of the sensor amplifies and shapes the signal, outputting a good rectangular pulse signal. The measurement frequency range is wider, the output signal is more accurate and stable, the installation is simple, and it is oil and waterproof. It has been widely used in speed measurement fields such as power, automotive, aviation, textile, petrochemical, etc
