topworx開關用于控制機械設(she)備的行程(cheng)(cheng)及限位保(bao)護(hu)。在(zai)實際生產(chan)中，將行程(cheng)(cheng)限位開(kai)關(guan)安裝在(zai)預先(xian)安排(pai)的位置，當(dang)裝于生產(chan)機械運動部件上的模塊撞擊行程(cheng)(cheng)開(kai)關(guan)時，行程(cheng)(cheng)限位開(kai)關(guan)的觸點動作，實現電路的切換。

topworx限(xian)位(wei)開(kai)關(guan)(guan)原(yuan)理是用以(yi)限(xian)定(ding)(ding)機械(xie)設備的(de)運(yun)(yun)(yun)動(dong)極限(xian)位(wei)置的(de)電(dian)(dian)氣開(kai)關(guan)(guan)。限(xian)位(wei)開(kai)關(guan)(guan)有(you)接(jie)觸式(shi)(shi)(shi)(shi)的(de)和非(fei)接(jie)觸式(shi)(shi)(shi)(shi)的(de)。接(jie)觸式(shi)(shi)(shi)(shi)的(de)比較(jiao)直觀，機械(xie)設備的(de)運(yun)(yun)(yun)動(dong)部件上(shang)(shang)，安裝上(shang)(shang)行(xing)(xing)(xing)程開(kai)關(guan)(guan)，與其相對運(yun)(yun)(yun)動(dong)的(de)固定(ding)(ding)點(dian)上(shang)(shang)安裝極限(xian)位(wei)置的(de)擋塊，或者(zhe)是相反安裝位(wei)置。當行(xing)(xing)(xing)程開(kai)關(guan)(guan)的(de)機械(xie)觸頭碰上(shang)(shang)擋塊時(shi)，切斷了(le)(或改變(bian)了(le))控(kong)制電(dian)(dian)路，機械(xie)就停止運(yun)(yun)(yun)行(xing)(xing)(xing)或改變(bian)運(yun)(yun)(yun)行(xing)(xing)(xing)。由于機械(xie)的(de)慣性運(yun)(yun)(yun)動(dong)，這種行(xing)(xing)(xing)程開(kai)關(guan)(guan)有(you)一定(ding)(ding)的(de)“超行(xing)(xing)(xing)程”以(yi)保護(hu)開(kai)關(guan)(guan)不受(shou)損壞。非(fei)接(jie)觸式(shi)(shi)(shi)(shi)的(de)形(xing)式(shi)(shi)(shi)(shi)很(hen)多，常見的(de)有(you)干簧(huang)管、光(guang)電(dian)(dian)式(shi)(shi)(shi)(shi)、感(gan)應式(shi)(shi)(shi)(shi)等，這幾種形(xing)式(shi)(shi)(shi)(shi)在(zai)電(dian)(dian)梯(ti)中都(dou)能夠見到。當然還有(you)更(geng)多的(de)先進形(xing)式(shi)(shi)(shi)(shi)。

適(shi)用場景(jing)：

1、適合用于(yu)旋(xuan)轉和線性應(ying)用;

2、認(ren)證為(wei)在所有危險區域中(zhong)使用;

3、集成(cheng)解決(jue)方案(an)(總線+傳感(gan)器+導閥);

4、在現場總線網絡中(zhong)處于(yu)技術一定(ding)的應用范圍(wei)。

因此，限(xian)位(wei)(wei)開(kai)關(guan)(guan)是一種根據(ju)運動部(bu)件的行(xing)程位(wei)(wei)置而切換電(dian)(dian)路(lu)的電(dian)(dian)器，它的作用(yong)(yong)(yong)原理(li)與按(an)鈕類似(si)。限(xian)位(wei)(wei)開(kai)關(guan)(guan)廣泛用(yong)(yong)(yong)于各類機(ji)床和起重機(ji)械(xie)，用(yong)(yong)(yong)以控(kong)制其行(xing)程、進行(xing)終(zhong)端限(xian)位(wei)(wei)保護。在電(dian)(dian)梯的控(kong)制電(dian)(dian)路(lu)中，還利用(yong)(yong)(yong)行(xing)程限(xian)位(wei)(wei)開(kai)關(guan)(guan)來控(kong)制開(kai)關(guan)(guan)轎門的速度(du)、自動開(kai)關(guan)(guan)門的限(xian)位(wei)(wei)，轎廂的上、下限(xian)位(wei)(wei)保護。
