style="text-indent:25px">限位開關(guān)主要是有一個擋塊壓住限位開關(guān)的觸頭，那么限位開關(guān)里面常開變常閉，常閉變常開，這種開關(guān)一般都用在一個運動物件兩個極端的限位，因為這種開關(guān)機(jī)械方面出故障比較低，使用環(huán)境要求不高，因此用的比較廣。感應(yīng)式限位開關(guān)，一般通過物體靠近限位開關(guān)有感應(yīng)常開變常閉，常閉變常開。但是這種開關(guān)使用的環(huán)境要求高一點，因此沒有機(jī)械式限位開關(guān)應(yīng)用廣fan。沒有記錯的話感應(yīng)式限位開關(guān)一般在氣缸，等一些部件上檢測位移或者壓力。機(jī)械式限位開關(guān)結(jié)構(gòu)簡單，成本低，對于控制要求不太敏感，環(huán)境要求一般，感應(yīng)式對于環(huán)境要求敏感，具體問題具體分析具體解決，成本較高。南京防爆限位開關(guān)工作原理限位開關(guān)在市場上可以覆蓋大多數(shù)限位應(yīng)用。</p><div
