接近開關(guān)定義與用途=∕∕∕

接近開關(guān)又稱無觸點(diǎn)行程開關(guān)，它除可以完成行程控制和限位保護(hù)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(guān)按工作原理可分為高頻振蕩型、電容型、感應(yīng)電橋型、*磁鐵型和霍耳效應(yīng)型等。

接近開關(guān)在航空、航天技術(shù)以及工業(yè)生產(chǎn)中都有廣泛的應(yīng)用。在日常生活中，如賓館、飯店、車庫的自動門，自動熱風(fēng)機(jī)上都有應(yīng)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(guān)組成的防盜裝置。在測量技術(shù)中，如長度，位置的測量；在控制技術(shù)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(guān)。
