接近開(kāi)關(guān)是與(機(jī)器的)運(yùn)動(dòng)部件無(wú)機(jī)械接觸而能操作的位置開(kāi)關(guān)。當(dāng)運(yùn)動(dòng)的物體靠近開(kāi)關(guān)到一定位置時(shí)，開(kāi)關(guān)發(fā)出信號(hào)，達(dá)到行程控制及計(jì)數(shù)自動(dòng)控制的開(kāi)關(guān)。通常用于工業(yè)自動(dòng)化控制系統(tǒng)中，實(shí)現(xiàn)檢測(cè)、控制，是一種無(wú)觸點(diǎn)、非接觸型的檢測(cè)裝置。接近開(kāi)關(guān)的種類(lèi)非常多，用于檢測(cè)金屬的和(或)非金屬的物體存在與否的電感式和電容接近開(kāi)關(guān)、能檢測(cè)反射聲音物體存在與否的超聲波式接近開(kāi)關(guān)、能檢測(cè)物體存在與否的光電式接近開(kāi)關(guān)盒能檢測(cè)磁性物體存在與否的非機(jī)械磁性式接近開(kāi)關(guān)適用標(biāo)準(zhǔn)為《低壓開(kāi)關(guān)設(shè)備和控制設(shè)備第5-2部分：控制電路電器和開(kāi)關(guān)元件接近開(kāi)關(guān)》;帶模擬量輸出的接近設(shè)備適用的標(biāo)準(zhǔn)為IEC60947-5-7：2003《低壓開(kāi)關(guān)設(shè)備和控制設(shè)備第5-7部分：控制電路電器和開(kāi)關(guān)元件用于帶模擬輸出的接近設(shè)備的要求》，相應(yīng)的國(guó)標(biāo)已完成制定即將發(fā)布實(shí)施，該標(biāo)準(zhǔn)修改了GB/中有關(guān)帶半導(dǎo)體開(kāi)關(guān)元件的接近開(kāi)關(guān)的要求，以適用于帶模擬輸出的接近設(shè)備。1.分類(lèi)由于位移傳感器可以根據(jù)不同的原理和不同的方法做成，而不同的位移傳感器對(duì)物體的“感知”方法也不同，因此接近開(kāi)關(guān)的種類(lèi)非常多，其類(lèi)型有電感式、電容式、光電式、超聲波式、霍爾式等。對(duì)于符合IEC60947-5-7標(biāo)準(zhǔn)的產(chǎn)品。</p><p>
