1. Introduction

The HK5516 speed sensor adopts magnetic sensing effect. When the metal teeth pass through the front end of the sensor, it causes a change in magnetic field. The sensor detects the change in magnetic field and converts it into an alternating electrical signal. The built-in circuit of the sensor amplifies and shapes the signal, and outputs a good rectangular pulse signal. The measurement frequency range is 1-20KHZ, and the output signal is stable. It is easy to install, oil and waterproof, and has been widely used in speed measurement fields such as power, automotive, aviation, textile, petrochemical, etc.
