由此便可“感知”有物體接近。6、其它型式其它型式的接近開關(guān)，當(dāng)觀察者或系統(tǒng)對波源的距離發(fā)生改變時，接近到的波的頻率會發(fā)生偏移，這種現(xiàn)象稱為多普勒效應(yīng)。聲納和雷達(dá)就是利用這個效應(yīng)的原理制成的。利用多普勒效應(yīng)可制成超聲波接近開關(guān)、微波接近開關(guān)等。當(dāng)有物體移近時，接近開關(guān)接收到的反射信號會產(chǎn)生多普勒頻移，由此可以識別出有無物體接近。主要功能1.檢驗距離檢測電梯、升降設(shè)備的停止、起動、通過位置；檢測車輛的位置，防止兩物體相撞檢測；檢測工作機(jī)械的設(shè)定位置，移動機(jī)器或部件的極限位置；檢測回轉(zhuǎn)體的停止位置，閥門的開或關(guān)位置。2.尺寸控制金屬板沖剪的尺寸控制裝置；自動選擇、鑒別金屬件長度；檢測自動裝卸時堆物高度；檢測物品的長、寬、高和體積。3.檢測物體存在有否檢測生產(chǎn)包裝線上有無產(chǎn)品包裝箱；檢測有無產(chǎn)品零件。4.轉(zhuǎn)速與速度控制控制傳送帶的速度；控制旋轉(zhuǎn)機(jī)械的轉(zhuǎn)速；與各種脈沖發(fā)生器一起控制轉(zhuǎn)速和轉(zhuǎn)數(shù)。5.計數(shù)及控制檢測生產(chǎn)線上流過的產(chǎn)品數(shù)；高速旋轉(zhuǎn)軸或盤的轉(zhuǎn)數(shù)計量；零部件計數(shù)。6.檢測異常檢測瓶蓋有無；產(chǎn)品合格與不合格判斷；檢測包裝盒內(nèi)的金屬制品缺乏與否；區(qū)分金屬與非金屬零件；產(chǎn)品有無標(biāo)牌檢測；起重機(jī)危險區(qū)報警。</p><p> 接近開關(guān)是與(機(jī)器的)運動部件無機(jī)械接觸而能操作的位置開關(guān)。當(dāng)運動的物體靠近開關(guān)到一定位置時，開關(guān)發(fā)出信號，達(dá)到行程控制及計數(shù)自動控制的開關(guān)。通常用于工業(yè)自動化控制系統(tǒng)中，實現(xiàn)檢測、控制，是一種無觸點、非接觸型的檢測裝置。接近開關(guān)的種類非常多，用于檢測金屬的和(或)非金屬的物體存在與否的電感式和電容接近開關(guān)、能檢測反射聲音物體存在與否的超聲波式接近開關(guān)、能檢測物體存在與否的光電式接近開關(guān)盒能檢測磁性物體存在與否的非機(jī)械磁性式接近開關(guān)適用標(biāo)準(zhǔn)為《低壓開關(guān)設(shè)備和控制設(shè)備第5-2部分：控制電路電器和開關(guān)元件接近開關(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《低壓開關(guān)設(shè)備和控制設(shè)備第5-7部分：控制電路電器和開關(guān)元件用于帶模擬輸出的接近設(shè)備的要求》，相應(yīng)的國標(biāo)已完成制定即將發(fā)布實施，該標(biāo)準(zhǔn)修改了GB/中有關(guān)帶半導(dǎo)體開關(guān)元件的接近開關(guān)的要求，以適用于帶模擬輸出的接近設(shè)備。1.分類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物體的“感知”方法也不同，因此接近開關(guān)的種類非常多，其類型有電感式、電容式、光電式、超聲波式、霍爾式等。對于符合IEC60947-5-7標(biāo)準(zhǔn)的產(chǎn)品。溫州接近開關(guān)質(zhì)量哪家好，歡迎來電咨詢，無錫日環(huán)傳感科技有限公司。</p><div

所以同一款標(biāo)準(zhǔn)的接近開關(guān)檢測不同的金屬時其感應(yīng)距離是不同的。下圖所示為某款接近開關(guān)檢測不同金屬時感應(yīng)距離與被測物材質(zhì)的關(guān)系。（當(dāng)然，現(xiàn)在也有一些特殊型號即衰減系數(shù)為1的接近開關(guān)，在檢測不同的金屬時可以做到有相同的感應(yīng)距離，但因為其價格較貴普及度不高，我們不做交流），由圖中可知，同一款傳感器檢測不同的金屬時其感應(yīng)距離相差還是很大的。從左到右依次為生鐵、不銹鋼、鉛、黃銅、鋁、紫銅第二點需要注意的是接近開關(guān)現(xiàn)場安裝時會有一個參數(shù)叫齊平、非齊平的（也有叫屏蔽、非屏蔽的）。如下圖。所謂齊平就是指接近開關(guān)感應(yīng)面與與周圍金屬殼體是齊平的，這種安裝方式的在使用時可以把接近開關(guān)埋在金屬載體中，只要感應(yīng)面不低于載體面就行。而非齊平類型的在安裝時其感應(yīng)面必須高出周圍金屬載體（非金屬載體則無此要求）。（在此順便普及一下為什么會有非齊平的方式：因為非齊平的感應(yīng)面其電磁場區(qū)域大，在同等尺寸的外殼下可以增加感應(yīng)距離，而大的感應(yīng)距離正是很多應(yīng)用所需要的，所以才有了非齊平的設(shè)計）。長春圓形接近開關(guān)參數(shù)</p><p>
