凸輪開關原理

凸輪(lun)(lun)開關(guan)的(de)(de)工作原理是(shi)(shi)因為(wei)凸輪(lun)(lun)控制器(qi)上(shang)套(tao)著很(hen)多的(de)(de)凸輪(lun)(lun)片(一(yi)般的(de)(de)也就是(shi)(shi)12片)，當手動輪(lun)(lun)經(jing)轉(zhuan)軸傳動轉(zhuan)為(wei)時，使觸(chu)(chu)(chu)點(dian)(dian)斷開或(huo)者閉合，就比如當凸輪(lun)(lun)處于一(yi)個位置時，觸(chu)(chu)(chu)點(dian)(dian)就是(shi)(shi)閉合的(de)(de);當凸輪(lun)(lun)轉(zhuan)位使轉(zhuan)子處于凸緣(yuan)時，觸(chu)(chu)(chu)點(dian)(dian)就會斷開。畢竟(jing)這些(xie)觸(chu)(chu)(chu)點(dian)(dian)的(de)(de)凸輪(lun)(lun)片的(de)(de)形狀(zhuang)不(bu)相同，因此這些(xie)觸(chu)(chu)(chu)點(dian)(dian)閉合規律也不(bu)相同，這樣才(cai)會符合不(bu)同的(de)(de)控制要(yao)求。

開關盒

開關盒可(ke)以直(zhi)接安裝在機器上(shang)，同(tong)時又具備IP65的(de)防(fang)護等級。

阻燃等級

LW42系列(lie)凸輪開(kai)關(guan)和安全開(kai)關(guan)材(cai)料(liao)均采用德國(guo)尼(ni)龍66制成，阻燃等級高達Vo級。

附件

開關護(hu)罩可以有效保(bao)護(hu)凸輪開關的觸(chu)點模塊不受灰(hui)塵(chen)及水氣的侵害，延長觸(chu)點使(shi)用壽命。
