行程開關(guān)就是一般所說的限位開關(guān)??梢岳斫鉃槭且唤M接通或斷開的簡單電路。
“用來檢測物體是否移動到限定的位置”,例如,機床的移動工作臺上裝撞塊,相對不動的床身上裝行程開關(guān),當(dāng)機床工作臺移動預(yù)先設(shè)定的距離后,工作臺上的撞塊壓動床身上安裝的行程開關(guān),行程開關(guān)斷開或接通,就有電信號反應(yīng)到控制柜中,工作臺停止移動或反向移動。
“原理是當(dāng)物體碰觸到限位開關(guān),開關(guān)的常開點閉合,常閉點斷開,用來控制電路或接受信號”
常開與常閉是開關(guān)的兩種原始狀態(tài),常開型一般指沒有壓下的狀態(tài)電路是開通的,常閉型一般指沒有壓下的狀態(tài)電路是斷開的。根據(jù)需要來進(jìn)行選擇,開關(guān)的常開點斷開或常閉點閉合。
如撞塊壓下行程開關(guān)常開點斷開(斷開電路)或常閉點閉合(接通電路)
常開接點:在不受外力(包括電力)的作用下,開關(guān)斷開的,就是常開接點。
物體碰觸到限位開關(guān),開關(guān)的常開點閉合,常閉點斷開,用來控制電路或接受信號。物體可以是任何機械裝置。行程開關(guān)與繼電器是不同的“開關(guān)”繼電器是有電磁線圈的,行程開關(guān)是沒有的,內(nèi)部只有開關(guān)接點,需要外力的作用才使開關(guān)轉(zhuǎn)換狀態(tài)。
限位開關(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(hù)的作用。最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。
