全封闭的霍尔接近开关

Hall proximity switches completely closed

文章介绍一种基于霍尔元件的全封闭接近开关,设计了实际运用线路,并将其运用于齿轮转速测试。该霍尔接近开关是将两相同性能的霍尔元件与磁钢(夹在两者之间)封闭在一个隔磁材料中,配以高抗干扰的电路,可以在各个领域得到运用。

This paper presents a proximity switch based on the fully enclosed in the Hall element,the actual use of the line is designed and applied to the gear speed test.The Hall proximity switches to the same performance of the Hall element and the magnet（sandwiched between the two） enclosed in a separated magnetic materials,together with the high noise immunity of the circuit can be in various fields use.
