style="text-indent:25px">限位開關(guān)定義：在電氣控制系統(tǒng)中，位置開關(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。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，將行程開關(guān)安裝在預(yù)先安排的位置，當(dāng)裝于生產(chǎn)機(jī)械運(yùn)動部件上的模塊撞擊行程開關(guān)時，行程開關(guān)的觸點(diǎn)動作，實(shí)現(xiàn)電路的切換。因此，行程開關(guān)是一種根據(jù)運(yùn)動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。行程開關(guān)廣fan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，還利用行程開關(guān)來控制開關(guān)轎門的速度、自動開關(guān)門的限位、轎廂的上、下限位保護(hù)。行程開關(guān)可以安裝在相對靜止的物體（如固定架、門框等，簡稱靜物）上或者運(yùn)動的物體（如行車、門等，簡稱動物）上。當(dāng)動物接近靜物時，開關(guān)的連桿驅(qū)動開關(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)的動作。隔爆型限位開關(guān)注意事項(xiàng)：本產(chǎn)品不能安裝在具有性氣體存在的環(huán)境。天津防爆限位開關(guān)APL</p><p

style="text-indent:25px">什么是限位開關(guān)？其實(shí)限位開關(guān)的種類比較多。限位開關(guān)一般分為機(jī)械式、電子感應(yīng)式和光電式三種。雖然它們的工作原理不同，但它們的功能是完全相同的。它是一種用于檢測移動電氣設(shè)備工作位置的裝置。讓我先談?wù)剻C(jī)械限位開關(guān)。限位開關(guān)通常被稱為行程開關(guān)或位置開關(guān)。其功能與控制按鈕相同。它可以將機(jī)械位移信號轉(zhuǎn)換成電信號，但觸點(diǎn)的動作不是用手按的。它是利用生產(chǎn)設(shè)備中某些運(yùn)動部件的機(jī)械位移與開關(guān)相撞，使觸點(diǎn)移動，完成對某一電路通斷的控制，從而控制機(jī)械動作或程序執(zhí)行。如果行程開關(guān)安裝在工作機(jī)器的末端以限制其行程，則稱為限位開關(guān)或端部開關(guān)。天津防爆限位開關(guān)APL</p></p><br
