AL-11R磁性開(kāi)關(guān)是通過(guò)磁鐵來(lái)感應(yīng)的，這個(gè)“磁”就是磁鐵，磁鐵也有好幾種，市場(chǎng)上面常用的磁鐵有橡膠磁、永磁鐵氧體、燒結(jié)釹鐵硼等。開(kāi)關(guān)就是干簧管了。干簧管是干式舌簧管的簡(jiǎn)稱，是一種有觸點(diǎn)的無(wú)源電子開(kāi)關(guān)元件，具有結(jié)構(gòu)簡(jiǎn)單，體積小便于控制等優(yōu)點(diǎn)，其外殼一般是一根密封的玻璃管，管中裝有兩個(gè)鐵質(zhì)的彈性磁片電板，還灌有惰性氣體。平時(shí)，玻璃管中的兩個(gè)由特殊材料制成的磁片是分開(kāi)的。當(dāng)有磁性物質(zhì)靠近玻璃管時(shí)，在磁場(chǎng)磁力線的作用下，管內(nèi)的兩個(gè)磁片被磁化而互相吸引接觸，磁片就會(huì)吸合在一起，使結(jié)點(diǎn)所接的電路連通。外磁力消失后，兩個(gè)磁片由于本身的彈性而分開(kāi)，線路也就斷開(kāi)了。因此，作為一種利用磁場(chǎng)信號(hào)來(lái)控制的線路開(kāi)關(guān)器件，干簧管可以作為傳感器用，用于計(jì)數(shù)，限位等等（在安防系統(tǒng)中主要用于門(mén)磁、窗磁的制作），同時(shí)還被廣泛使用于各種通信設(shè)備中。
