產品介紹
是專業做限位開關的一個品牌， SCHMERSAL限位開關就是用以限定機械設備的運動極限位置的電氣開關SCHMERSAL。限位開關有接觸式的和非接觸式的。接觸式的比較直觀，機械設備的運動部件上，安裝上行程開關，與其相對運動的固定點上安裝極限位置的擋塊，或者是相反安裝位置。當行程開關的機械觸頭碰上擋塊時，切斷了（或改變了）控制電路，機械就停止運行或改變運行。由于機械的慣性運動，這種行程開關有一定的“超行程”以保護開關不受損壞。非接觸式的形式很多，常見的有干簧管、光電式、感應式等，這幾種形式在電梯中都能夠見到。當然還有更多的*形式。
SCHMERSAL施邁賽限位開關是一種常用的小電流主令電器。利用生產機械運動部件的碰撞使其觸頭動作來實現接通或分斷控制電路，達到一定的控制目的。通常，這類開關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。
在電氣控制系統中，限位開關的作用是實現順序控制、定位控制和位置狀態的檢測。用于控制機械設備的行程及限位保護。構造：由操作頭、觸點系統和外殼組成。
在實際生產中，將SCHMERSAL限位開關安裝在預先安排的位置，當裝于生產機械運動部件上的模塊撞擊行程開關時，限位開關的觸點動作，實現電路的切換。因此，行程開關是一種根據運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。
SCHMERSAL限位開關廣泛用于各類機床和起重機械，用以控制其行程、進行終端限位保護。在電梯的控制電路中，還利用行程開關來控制開關轎門的速度、自動開關門的限位，轎廂的上、下限位保護。
