style="text-indent:25px">限位開關(guān)是一種位移傳感器，對接近的物體有感應(yīng)能力的，通過這個傳感器來完成控制開關(guān)的任務(wù)。通常接近開關(guān)都有一個檢出距離，即開關(guān)對物體的感知的可測范圍，不同的傳感器對物體的感知能力不同，取決于響應(yīng)的頻率。根據(jù)對外物感應(yīng)能力的不同，限位開關(guān)有不同的種類:對電容器的極板進行感應(yīng)的是電容接近開關(guān)，不論對象是否為導體，只要電容的常數(shù)改變，就可以斷定有物體接近，從而控制開關(guān)的開合，但前提是該物體需為導電體;通過溫度感應(yīng)的開關(guān)是熱釋電接近開關(guān)，將該開關(guān)放于檢測面上，有溫度與環(huán)境不同的外物接近時，器件的輸出數(shù)據(jù)就會發(fā)生變化，從而達到檢測的目的。</p><p style="text-indent:25px">限位開關(guān)主要是有一個擋塊壓住限位開關(guān)的觸頭，那么限位開關(guān)里面常開變常閉，常閉變常開，這種開關(guān)一般都用在一個運動物件兩個極端的限位，因為這種開關(guān)機械方面出故障比較低，使用環(huán)境要求不高，因此用的比較廣。感應(yīng)式限位開關(guān)，一般通過物體靠近限位開關(guān)有感應(yīng)常開變常閉，常閉變常開。但是這種開關(guān)使用的環(huán)境要求高一點，因此沒有機械式限位開關(guān)應(yīng)用普遍。沒有記錯的話感應(yīng)式限位開關(guān)一般在氣缸，等一些部件上檢測位移或者壓力。機械式限位開關(guān)結(jié)構(gòu)簡單，成本低，對于控制要求不太敏感，環(huán)境要求一般，感應(yīng)式對于環(huán)境要求敏感，具體問題具體分析具體解決，成本較高。限位開關(guān)有接觸式的和非接觸式的。如果行程開關(guān)安裝在工作機器的末端以限制其行程，則稱為限位開關(guān)或端部開關(guān)。</p><div

style="text-indent:25px">行程開關(guān)的應(yīng)用方面很多，很多電器里面都有它的身影。那這么簡單的開關(guān)能起什么作用呢？它主要是起連鎖保護的作用。常見的例子莫過于其在洗衣機和錄音機（錄像機）中的應(yīng)用了。在洗衣機的脫水（甩干）過程中轉(zhuǎn)速很高，如果此時有人由于疏忽打開洗衣機的門或蓋后，再把手伸進去，很容易對人造成傷害，為了避免這種事故的發(fā)生，在洗衣機的門或蓋上裝了個電接點，一旦有人開啟洗衣機的門或蓋時，就自動把電機斷電，甚至還要靠機械辦法聯(lián)動，使門或蓋一打開就立刻“剎車”，強迫轉(zhuǎn)動著的部件停下來，免得傷害人身。在錄音機和錄像機中，我們常常使用到快進或者倒帶，磁帶急速地轉(zhuǎn)動，但是當?shù)竭_磁帶的端點時會自動停下來。在這里行程開關(guān)又一次發(fā)揮了作用，不過這一次不是靠碰撞而是靠磁帶的張力的突然增大引起動作的。無錫閥門限位開關(guān)制造企業(yè)</p></p><br
