style="text-indent:25px">限位開關(guān)，指為保護內(nèi)置微動開關(guān)免受外力、水、油、氣體和塵埃等的損害，而組裝在外殼內(nèi)的開關(guān)，尤其適用于對機械強度和環(huán)境適應(yīng)性有特殊要求的地方。形狀大致分為橫向型、豎向型和復(fù)合型。限位開關(guān)大致上是由五個構(gòu)成要素組成的。限位開關(guān)主要由開關(guān)元件，接線端子，開關(guān)操動件，傳動部分組成，根據(jù)開關(guān)觸頭接通和斷開機械機理，開關(guān)元件有下屬二類。1.緩動開關(guān)：緩動開關(guān):開關(guān)的接通和斷開動作切換時間與開關(guān)操作頻率有關(guān)，操作頻率越快，開關(guān)的切換也越快。2.速度開關(guān)：速度開關(guān):開關(guān)的接通和斷開的轉(zhuǎn)換時間與開關(guān)**作的頻率無關(guān)，只要開關(guān)**作到一定位置，開關(guān)便發(fā)生接通和斷開切換，此過程時間一般為彈簧彈跳所需時間，此時間段為一常數(shù)。</p><p style="text-indent:25px">在數(shù)控雕刻機設(shè)備上，通常會安裝多個限位開關(guān)，此時，限位開關(guān)的主要作用是作為機床回零信號的反饋裝置。目前，采用的感應(yīng)式接近開關(guān)，感應(yīng)距離可達1到5毫米，反應(yīng)速度可以達毫秒級。當(dāng)限位開關(guān)感應(yīng)到鐵質(zhì)障礙物時，會輸出一個低電平有效電信號給系統(tǒng)，系統(tǒng)收到信號后減速的同時，往反方向移動一定距離后停止，這就完成了機床的回零動作。在具體選用限位開關(guān)產(chǎn)品時，如果選用的限位開關(guān)響應(yīng)速度慢，反饋信號異常，就會導(dǎo)致機床回零不準，影響雕刻機的精度；如果限位開關(guān)抗干擾能力差，變頻器等其他干擾電器會導(dǎo)致限位觸發(fā)報警，影響雕刻機正常使用。另外，如果限位開關(guān)抗沖擊能力差，加之系統(tǒng)板卡輸出電壓不穩(wěn)定，則比較容易擊穿限位開關(guān)內(nèi)部元器件，導(dǎo)致限位開關(guān)失靈損壞，較終使雕刻機無法正?；貦C床零點。因此，在選用限位開關(guān)設(shè)備時，應(yīng)注意選用響應(yīng)速度快、抗干擾和抗沖擊能力強的質(zhì)量過關(guān)的限位開關(guān)產(chǎn)品。限位開關(guān)的日常保養(yǎng)方法：電路電壓和電流的定期檢測，電路中的電流電壓對限位開關(guān)原件的影響是非常大的。</p><div

/位置開關(guān)），是一種常用的小電流電器。利用生產(chǎn)機械運動部件的碰撞使其觸頭動作來實現(xiàn)接通或分斷控制電路，達到一定的控制目的。通常，這類開關(guān)被用來限制機械運動的位置或行程，使運動機械按一定位置或行程自動停止、反向運動、變速運動或自動往返運動等。為了提高控制設(shè)備的穩(wěn)定性和可靠性，可將多個限位開關(guān)進行復(fù)合控制使用。目前常用的限位開關(guān)有機械式、光電式、感應(yīng)式等幾種，其中機械式限位開關(guān)是一種接觸式限位開關(guān)，光電式和感應(yīng)式限位開關(guān)則屬于非接觸式限位開關(guān),在這幾種限位開關(guān)中，無論采用哪一種，都必須在其運動部件所經(jīng)過的需限位的地方固定安裝限位開關(guān)部件。無錫防爆限位開關(guān)報價</p></p><br
