德國(guó)原裝巴魯夫BALLUFF限位開(kāi)關(guān)總代理 限位開(kāi)關(guān)廣泛用于各類機(jī)床和起重機(jī)械，用以控制其行程、進(jìn)行終端限位保護(hù)。在電梯的控制電路中，還利用行程開(kāi)關(guān)來(lái)控制開(kāi)關(guān)轎門的速度、自動(dòng)開(kāi)關(guān)門的限位，轎廂的上、下限位保護(hù)。
日常生活
限位開(kāi)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(jiǎn)單的開(kāi)關(guān)能起什么作用呢？它主要是起連鎖保護(hù)的作用。zui常見(jiàn)的例子莫過(guò)于其在洗衣機(jī)和錄音機(jī)（錄像機(jī)）中的應(yīng)用了。
在洗衣機(jī)的脫水（甩干）過(guò)程中轉(zhuǎn)速很高，如果此時(shí)有人由于疏忽打開(kāi)洗衣機(jī)的門或蓋后，再把手伸進(jìn)去，很容易對(duì)人造成傷害，為了避免這種事故的發(fā)生，在洗衣機(jī)的門或蓋上裝了個(gè)電接點(diǎn)，一旦有人開(kāi)啟洗衣機(jī)的門或蓋時(shí)，就自動(dòng)把電機(jī)斷電，甚至還要靠機(jī)械辦法聯(lián)動(dòng)，使門或蓋一打開(kāi)就立刻“剎車”，強(qiáng)迫轉(zhuǎn)動(dòng)著的部件停下來(lái)，免得傷害人身。
在錄音機(jī)和錄像機(jī)中，我們常常使用到快進(jìn)或者倒帶，磁帶急速地轉(zhuǎn)動(dòng)，但是當(dāng)?shù)竭_(dá)磁帶的端點(diǎn)時(shí)會(huì)自動(dòng)停下來(lái)。在這里行程開(kāi)關(guān)又一次發(fā)揮了作用，不過(guò)這一次不是靠碰撞而是靠磁帶的張力的突然增大引起動(dòng)作的。 德國(guó)原裝巴魯夫BALLUFF限位開(kāi)關(guān)總代理 限位開(kāi)關(guān)是一種常用的小電流主令電器。利用生產(chǎn)機(jī)械運(yùn)動(dòng)部件的碰撞使其觸頭動(dòng)作來(lái)實(shí)現(xiàn)接通或分?jǐn)嗫刂齐娐?，達(dá)到一定的控制目的。通常，這類開(kāi)關(guān)被用來(lái)限制機(jī)械運(yùn)動(dòng)的位置或行程，使運(yùn)動(dòng)機(jī)械按一定位置或行程自動(dòng)停止、反向運(yùn)動(dòng)、變速運(yùn)動(dòng)或自動(dòng)往返運(yùn)動(dòng)等。
在電氣控制系統(tǒng)中，限位開(kāi)關(guān)的作用是實(shí)現(xiàn)順序控制、定位控制和位置狀態(tài)的檢測(cè)。用于控制機(jī)械設(shè)備的行程及限位保護(hù)。構(gòu)造：由操作頭、觸點(diǎn)系統(tǒng)和外殼組成。
在實(shí)際生產(chǎn)中，將限位開(kāi)關(guān)安裝在預(yù)先安排的位置，當(dāng)裝于生產(chǎn)機(jī)械運(yùn)動(dòng)部件上的模塊撞擊行程開(kāi)關(guān)時(shí)，限位開(kāi)關(guān)的觸點(diǎn)動(dòng)作，實(shí)現(xiàn)電路的切換。因此，行程開(kāi)關(guān)是一種根據(jù)運(yùn)動(dòng)部件的行程位置而切換電路的電器，它的作用原理與按鈕類似。
Balluff巴魯夫限位開(kāi)關(guān)就是用以限定機(jī)械設(shè)備的運(yùn)動(dòng)極限位置的電氣開(kāi)關(guān)。限位開(kāi)關(guān)有接觸式的和非接觸式的。接觸式的比較直觀，機(jī)械設(shè)備的運(yùn)動(dòng)部件上，安裝上行程開(kāi)關(guān)，與其相對(duì)運(yùn)動(dòng)的固定點(diǎn)上安裝極限位置的擋塊，或者是相反安裝位置。當(dāng)行程開(kāi)關(guān)的機(jī)械觸頭碰上擋塊時(shí)，切斷了（或改變了）控制電路，機(jī)械就停止運(yùn)行或改變運(yùn)行。由于機(jī)械的慣性運(yùn)動(dòng)，這種行程開(kāi)關(guān)有一定的“超行程”以保護(hù)開(kāi)關(guān)不受損壞。非接觸式的形式很多，常見(jiàn)的有干簧管、光電式、感應(yīng)式等，這幾種形式在電梯中都能夠見(jiàn)到。當(dāng)然還有更多的*形式。 德國(guó)原裝巴魯夫BALLUFF限位開(kāi)關(guān)總代理
