磁性開關、AL-51R是通過磁鐵來感應的,這個磁就是磁鐵,磁鐵也有好幾種,市場上面常用的磁鐵有橡膠磁、永磁鐵氧體、燒結釹鐵硼等。開關就是干簧管了。干簧管是干式舌簧管的簡稱,是一種有觸點的無源電子開關元件,具有結構簡單,體積小便于控制等優(yōu)點,其外殼一般是一根密封的玻璃管,管中裝有兩個鐵質的彈性磁片電板,還灌有一種叫金屬銠的惰性氣體。平時,玻璃管中的兩個由特殊材料制成的磁片是分開的。當有磁性物質靠近玻璃管時,在磁場磁力線的作用下,管內的兩個磁片被磁化而互相吸引接觸,磁片就會吸合在一起,使結點所接的電路連通。外磁力消失后,兩個磁片由于本身的彈性而分開,線路也就斷開了。因此,作為一種利用磁場信號來控制的線路開關器件,干簧管可以作為傳感器用,用于計數(shù),限位等等(在安防系統(tǒng)中主要用于門磁、窗磁的制作),同時還被廣泛使用于各種通信設備中。在實際運用中,通常用永磁鐵控制這兩根金屬片的接通與否,所以又被稱為“磁控管”。
