style="text-indent:25px">限位開關(guān)、接近開關(guān)和光電開關(guān)是三種原理不同的傳感器，但作用一樣，都是檢測(cè)位置用的。那么讓我們看一下它們的區(qū)別； ①外形：限位開關(guān)一般是由一個(gè)明顯的動(dòng)作部位，而且該部位可以來回運(yùn)動(dòng)，運(yùn)動(dòng)角度不同，有的可以180度，有的只能90度。接近開關(guān)比較簡(jiǎn)單，只是單獨(dú)的一個(gè)傳感器。有些光電開關(guān)的外形與接近開關(guān)一致，但有些則完全不同，需要有發(fā)射和接收兩部分組成。 ②檢測(cè)距離：限位開關(guān)需要與檢測(cè)物質(zhì)直接接觸。接近開關(guān)較近，一般檢測(cè)范圍一般是3-20mm，取決與傳感器，接近開關(guān)的檢測(cè)距離很大程度上與檢測(cè)頭的直徑有關(guān)，即檢測(cè)距離越大，需要的直徑越大。而光電開關(guān)的檢測(cè)距離一般很長(zhǎng)，有些甚至可以達(dá)到幾米。這是一個(gè)明顯優(yōu)于接近開關(guān)的特點(diǎn)，但光電開關(guān)的原理與光有關(guān)，那么它就有一個(gè)明顯的缺點(diǎn)，法國(guó)溯高美負(fù)荷隔離開關(guān)價(jià)格，那就是容易受到水汽灰塵等影響，法國(guó)溯高美負(fù)荷隔離開關(guān)價(jià)格，法國(guó)溯高美負(fù)荷隔離開關(guān)價(jià)格，一旦水汽灰塵將檢測(cè)路線遮擋，傳感器就會(huì)失靈，而接近開關(guān)檢測(cè)金屬就沒有這個(gè)問題。法國(guó)溯高美負(fù)荷隔離開關(guān)價(jià)格</p><div

①限位開關(guān)：也可以叫行程開關(guān)；可以安裝在相對(duì)靜止的物體(如固定架、門框等，簡(jiǎn)稱靜物)上或者運(yùn)動(dòng)的物體（如行車、門等）上。當(dāng)物體接近靜物時(shí)，開關(guān)的連桿驅(qū)動(dòng)開關(guān)的接點(diǎn)引起閉合的接點(diǎn)分?jǐn)嗷蛘邤嚅_的接點(diǎn)閉合。由開關(guān)接點(diǎn)開、合狀態(tài)的改變?nèi)タ刂齐娐泛蜋C(jī)構(gòu)的動(dòng)作。 ②接近開關(guān)：一種無需與運(yùn)動(dòng)部件進(jìn)行機(jī)械直接接觸而可以操作的檢測(cè)位置的傳感器，接近開關(guān)又稱無觸點(diǎn)行程開關(guān)，它可以完成行程控制和限位保護(hù)等。該傳感器無需與檢測(cè)物質(zhì)接觸，但是檢測(cè)物質(zhì)的材質(zhì)需要是金屬，因?yàn)闊o需與檢測(cè)接觸，因此它的特點(diǎn)是工作可靠、壽命長(zhǎng)、功耗低、復(fù)定位精度高、操作頻率高以及適應(yīng)惡劣的工作環(huán)境等。 ③光電開關(guān)；它是利用被檢測(cè)物對(duì)光束的遮擋或反射，由同步回路接通電路，從而檢測(cè)物體的有無。物體不限于金屬，所有能反射光線（或者對(duì)光線有遮擋作用）的物體均可以被檢測(cè)。法國(guó)溯高美負(fù)荷隔離開關(guān)價(jià)格</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">限位開關(guān)、接近開關(guān)和光電開關(guān)是三種原理不同的傳感器，但作用一樣，都是檢測(cè)位置用的。其功能和應(yīng)用場(chǎng)合分別為： 1、限位開關(guān)為機(jī)械開關(guān)，試用于不是很使用頻率不是很頻繁場(chǎng)合，除此之外，有些機(jī)械開關(guān)可以做成全金屬，就可以工作在高溫場(chǎng)合，這是其他傳感器做不到的。 2、接近開關(guān)壽命較長(zhǎng)，適用于“通過信號(hào)”。氣缸上的位置檢測(cè)一般都是接近開關(guān)。但因接近開關(guān)內(nèi)部也有電路，因此不能應(yīng)用在強(qiáng)磁干擾的地方。 3、光電開關(guān)應(yīng)用較廣，只需要有物體遮擋光源即可觸發(fā)，因此不能應(yīng)用在灰塵較大的地方和強(qiáng)磁干擾的地方。</p><p style="text-indent:25px">磁性開關(guān)是一種利用磁場(chǎng)信號(hào)來控制的線路開關(guān)器件，也叫磁控開關(guān)。磁性開關(guān)的作用只是感應(yīng)到活塞桿了發(fā)出一個(gè)信號(hào)給PLC , 磁性開關(guān)不是限位用的，只是用作自動(dòng)控制中提供給PLC等氣缸狀態(tài)的傳感器, 它只能反饋氣缸是否到位，不能夠用于定位。磁性開關(guān)只會(huì)發(fā)出一個(gè)到位信號(hào)，行程的限制需要機(jī)械限位。如果你的汽缸負(fù)載大受外力或者慣性很大，氣體是被壓縮的。活塞桿就會(huì)移動(dòng)，所以如果要準(zhǔn)確位置，還是需要機(jī)械限位的。所以精確控制肯定不行的，一般沒多大要求的，也可以采用磁性開關(guān)限位，但只能是粗略的定位，要求不高的場(chǎng)合，可以省個(gè)行程開關(guān)！</p><div
