磁性開關(guān)、AL-18R氣缸磁性開關(guān)可替代臺灣磁性開關(guān)CS1-A磁性開關(guān)用于檢測氣缸行程的位置，不需再行程兩端設(shè)置機控閥（或行程開關(guān)）及其安裝架，不需要在活塞桿端部設(shè)置撞塊，所以使用方便、結(jié)構(gòu)緊湊?？煽啃愿撸瑝勖L、成本低、開關(guān)反應(yīng)時間快，故得到廣泛應(yīng)用。
氣缸磁性開關(guān)工作原理
氣缸磁性開關(guān)是將磁性開關(guān)裝在氣缸的缸筒外側(cè)。氣缸可以使各種型號的氣缸，但缸筒必須是導(dǎo)磁性弱、隔磁性強的材料，如硬鋁、不銹鋼、黃銅等。在非磁性體的活塞上安裝一個永磁鐵（橡膠磁鐵）的磁環(huán)，隨活塞移動的磁環(huán)靠近開關(guān)時，舌簧開關(guān)的兩根磁片被磁化而相互吸引，觸點閉合；當(dāng)磁環(huán)移開開關(guān)后，磁片失磁，觸點斷開。出點閉合或斷開時發(fā)出電信號（或使電信號消失），控制相應(yīng)電磁閥完成切換動作。如下圖所示。磁性開關(guān)內(nèi)部一般還帶有開關(guān)動作的指示燈和過電壓保護電路，用樹脂塑封在一個殼體內(nèi)。
