HS-S40-L霍尔磁性传感器

1. Introduction

Hall magnetic sensors are a type of magnetic field sensor made based on the Hall effect.The full-potential Hall effect is a type of magneto-electric effect.When the magnet approaches its sprinting surface, the switch outputs a low level; when the magnet is removed, the switch outputs a high level.
