Schmersal限位開關BN 32-R性能特點

產品作用:

限(xian)(xian)位(wei)開關(guan)(guan)就(jiu)是用(yong)以限(xian)(xian)定機(ji)(ji)械(xie)設備的(de)(de)運(yun)動(dong)極(ji)限(xian)(xian)位(wei)置的(de)(de)電(dian)氣開關(guan)(guan)。[2]限(xian)(xian)位(wei)開關(guan)(guan)有接觸(chu)式的(de)(de)和非接觸(chu)式的(de)(de)。接觸(chu)式的(de)(de)比較(jiao)直觀(guan)，機(ji)(ji)械(xie)設備的(de)(de)運(yun)動(dong)部件(jian)上(shang)，安(an)(an)裝(zhuang)上(shang)行程(cheng)開關(guan)(guan)，與其相對運(yun)動(dong)的(de)(de)固定點(dian)上(shang)安(an)(an)裝(zhuang)極(ji)限(xian)(xian)位(wei)置的(de)(de)擋塊(kuai)，或(huo)(huo)者是相反安(an)(an)裝(zhuang)位(wei)置。當行程(cheng)開關(guan)(guan)的(de)(de)機(ji)(ji)械(xie)觸(chu)頭碰上(shang)擋塊(kuai)時，切斷(duan)了(le)(或(huo)(huo)改變了(le))控制電(dian)路，機(ji)(ji)械(xie)就(jiu)停(ting)止(zhi)運(yun)行或(huo)(huo)改變運(yun)行。由于機(ji)(ji)械(xie)的(de)(de)慣性運(yun)動(dong)，這種行程(cheng)開關(guan)(guan)有一定的(de)(de)"超行程(cheng)"以保(bao)護(hu)開關(guan)(guan)不受損壞。非接觸(chu)式的(de)(de)形(xing)式很多(duo)，常見的(de)(de)有干簧管、光電(dian)式、感(gan)應(ying)式等，這幾種形(xing)式在(zai)電(dian)梯中都(dou)能夠見到。當然還(huan)有更(geng)多(duo)的(de)(de)*形(xing)式。

限(xian)(xian)(xian)(xian)(xian)位(wei)開(kai)關(guan)分工(gong)(gong)(gong)作(zuo)(zuo)限(xian)(xian)(xian)(xian)(xian)位(wei)開(kai)關(guan)和極(ji)限(xian)(xian)(xian)(xian)(xian)限(xian)(xian)(xian)(xian)(xian)位(wei)開(kai)關(guan)，工(gong)(gong)(gong)作(zuo)(zuo)限(xian)(xian)(xian)(xian)(xian)位(wei)開(kai)關(guan)是用來(lai)(lai)給出機(ji)(ji)構(gou)(gou)動(dong)作(zuo)(zuo)到(dao)位(wei)信號(hao)的(de)(de)(de)。極(ji)限(xian)(xian)(xian)(xian)(xian)限(xian)(xian)(xian)(xian)(xian)位(wei)開(kai)關(guan)是防止機(ji)(ji)構(gou)(gou)動(dong)作(zuo)(zuo)超出設計范圍(wei)而發生事故的(de)(de)(de)。工(gong)(gong)(gong)作(zuo)(zuo)限(xian)(xian)(xian)(xian)(xian)位(wei)開(kai)關(guan)安(an)裝在機(ji)(ji)構(gou)(gou)需(xu)要(yao)改變工(gong)(gong)(gong)況的(de)(de)(de)位(wei)置，開(kai)關(guan)動(dong)作(zuo)(zuo)后(hou)，給出信號(hao)，進(jin)行(xing)別的(de)(de)(de)相關(guan)動(dong)作(zuo)(zuo)。極(ji)限(xian)(xian)(xian)(xian)(xian)限(xian)(xian)(xian)(xian)(xian)位(wei)開(kai)關(guan)安(an)裝在機(ji)(ji)構(gou)(gou)動(dong)作(zuo)(zuo)的(de)(de)(de)最(zui)遠端，用來(lai)(lai)保護機(ji)(ji)構(gou)(gou)動(dong)作(zuo)(zuo)過大出現機(ji)(ji)構(gou)(gou)損(sun)壞。

限(xian)位(wei)(wei)開關(guan)，指為保(bao)護內置微動(dong)開關(guan)免受外力(li)、水、油、氣體和塵埃等(deng)的(de)損(sun)害(hai)，而組裝在外殼內的(de)開關(guan)，尤其適用于對機(ji)械強度和環境(jing)適應 性有特殊要求的(de)地方。 形(xing)狀大致分為橫向型(xing)、豎(shu)向型(xing)和復合型(xing)。下圖表示典型(xing)的(de)豎(shu)向型(xing)限(xian)位(wei)(wei)開關(guan)的(de)構(gou)造。限(xian)位(wei)(wei)開關(guan)大致上(shang)是由五個構(gou)成要素組成的(de)。

除了機(ji)械操作的(de)(de)(de)限位開(kai)關(guan)外，磁簧開(kai)關(guan)的(de)(de)(de)重(zhong)要性(xing)也在(zai)增(zeng)加。它們通常被用來(lai)與柱塞、滾(gun)輪(lun)和旋轉桿的(de)(de)(de)限位開(kai)關(guan)互補，且被認為是連接(jie)(jie)無觸(chu)點(dian)和非(fei)接(jie)(jie)觸(chu)式限位開(kai)關(guan)的(de)(de)(de)重(zhong)要環節。
