供應(yīng)TS-236-11Z-M20236TS0接近開關(guān)行程開關(guān)行程開關(guān)、限位開關(guān)
本開關(guān)用于控制機(jī)械設(shè)備的行程及限位保護(hù)。在實際生產(chǎn)中，將行程限位開關(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，行程限位開關(guān)的觸點(diǎn)動作，實現(xiàn)電路的切換。因此，限位開關(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。限位開關(guān)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，還利用行程限位開關(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)。
