在工廠的實(shí)際應(yīng)用中很多人分不清限位開關(guān)，光電開關(guān)和接近開關(guān)的區(qū)別，普及一下。首先限位開關(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。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。限位開關(guān)也可分為旋轉(zhuǎn)限位開關(guān)及直行限位開關(guān)。限位開關(guān)的內(nèi)部主要是機(jī)械觸點(diǎn)，觸點(diǎn)可以是常開，也可以是常閉。該觸點(diǎn)無源，所以不分NPN和PNP，進(jìn)線是24V，出線也是24V；因此不挑剔PLC。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、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。接近開關(guān)分為PNP和NPN兩種，因此在選擇傳感器時(shí)需要確認(rèn)好PLC的接法。光電開關(guān)；它是利用被檢測(cè)物對(duì)光束的遮擋或反射。淮安電感式接近開關(guān)廠家泰州光電接近開關(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
