接近開關定義與用途=∕∕∕
接近開關又稱無觸點行程開關，它除可以完成行程控制和限位保護外，還是一種非接觸型的檢測裝置，用作檢測零件尺寸和測速等，也可用于變頻計數(shù)器、變頻脈沖發(fā)生器、液面控制和加工程序的自動銜接等。接近開關按工作原理可分為高頻振蕩型、電容型、感應電橋型、永久磁鐵型和霍耳效應型等。
接近開關在航空、航天技術以及工業(yè)生產(chǎn)中都有廣泛的應用。在日常生活中，如賓館、飯店、車庫的自動門，自動熱風機上都有應用。在安全防盜方面，如資料檔案、財會、金融、博物館、金庫等重地，通常都裝有由各種接近開關組成的防盜裝置。在測量技術中，如長度，位置的測量；在控制技術中，如位移、速度、加速度的測量和控制，也都使用著大量的接近開關。
