氣缸磁性開(kāi)關(guān)、AL-19R臺(tái)灣磁性開(kāi)關(guān)是專(zhuān)用于拉桿缸、全金屬結(jié)構(gòu)、堅(jiān)固耐撞擊開(kāi)關(guān)夾具一體化，適用于全缸徑拉桿缸圓筒型設(shè)計(jì)、緊貼氣缸缸壁、感應(yīng)良好。
氣缸磁性開(kāi)關(guān)、AL-19R適用于32mm-125mm缸徑拉桿缸，開(kāi)關(guān)自帶夾具，方便使用，全金屬結(jié)構(gòu)超低壓降，兩線式帶指示燈開(kāi)關(guān)，于1000mA輸出時(shí)，僅1.0V壓降，使用壽命長(zhǎng)；可取代AL-21系列及亞德克CS1-F及CS1-U
用于檢測(cè)氣缸行程的位置，不需再行程兩端設(shè)置機(jī)控閥（或行程開(kāi)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(zhǎng)、成本低、開(kāi)關(guān)反應(yīng)時(shí)間快，故得到廣泛應(yīng)用。
氣缸磁性開(kāi)關(guān)工作原理
氣缸磁性開(kāi)關(guān)是將磁性開(kāi)關(guān)裝在氣缸的缸筒外側(cè)。氣缸可以使各種型號(hào)的氣缸，但缸筒必須是導(dǎo)磁性弱、隔磁性強(qiáng)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(gè)永磁鐵（橡膠磁鐵）的磁環(huán)，隨活塞移動(dòng)的磁環(huán)靠近開(kāi)關(guān)時(shí)，舌簧開(kāi)關(guān)的兩根磁片被磁化而相互吸引，觸點(diǎn)閉合；當(dāng)磁環(huán)移開(kāi)開(kāi)關(guān)后，磁片失磁，觸點(diǎn)斷開(kāi)。出點(diǎn)閉合或斷開(kāi)時(shí)發(fā)出電信號(hào)（或使電信號(hào)消失），控制相應(yīng)電磁閥完成切換動(dòng)作。如下圖所示。磁性開(kāi)關(guān)內(nèi)部一般還帶有開(kāi)關(guān)動(dòng)作的指示燈和過(guò)電壓保護(hù)電路，用樹(shù)脂塑封在一個(gè)殼體內(nèi)。
