講解WENGLOR鏡反射傳感器 通用型

特點概覽:

光(guang)(guang)(guang)電(dian)(dian)(dian)傳感(gan)器(qi)是將光(guang)(guang)(guang)信(xin)號轉換為電(dian)(dian)(dian)信(xin)號的(de)一種器(qi)件(jian)。其工作原(yuan)理基于光(guang)(guang)(guang)電(dian)(dian)(dian)效(xiao)應(ying)。光(guang)(guang)(guang)電(dian)(dian)(dian)效(xiao)應(ying)是指光(guang)(guang)(guang)照射在某(mou)些物質(zhi)上時，物質(zhi)的(de)電(dian)(dian)(dian)子吸收光(guang)(guang)(guang)子的(de)能(neng)量(liang)而發生了(le)相應(ying)的(de)電(dian)(dian)(dian)效(xiao)應(ying)現象。根據光(guang)(guang)(guang)電(dian)(dian)(dian)效(xiao)應(ying)現象的(de)不同將光(guang)(guang)(guang)電(dian)(dian)(dian)效(xiao)應(ying)分為三類(lei)：外(wai)光(guang)(guang)(guang)電(dian)(dian)(dian)效(xiao)應(ying)、內光(guang)(guang)(guang)電(dian)(dian)(dian)效(xiao)應(ying)及光(guang)(guang)(guang)生伏(fu)應。

光(guang)電(dian)(dian)(dian)(dian)(dian)傳感器一(yi)(yi)般由(you)處理通路(lu)和處理元(yuan)件2 部分(fen)組成。其(qi)基本原理是(shi)以(yi)光(guang)電(dian)(dian)(dian)(dian)(dian)效(xiao)應為基礎，把被測(ce)量(liang)的變化(hua)轉換成光(guang)信號的變化(hua)，然后借助光(guang)電(dian)(dian)(dian)(dian)(dian)元(yuan)件進一(yi)(yi)步(bu)將非電(dian)(dian)(dian)(dian)(dian)信號轉換成電(dian)(dian)(dian)(dian)(dian)信號。光(guang)電(dian)(dian)(dian)(dian)(dian)效(xiao)應是(shi)指用(yong)光(guang)照(zhao)射(she)某一(yi)(yi)物體(ti)，可以(yi)看作是(shi)一(yi)(yi)連串帶(dai)有一(yi)(yi)定能(neng)量(liang)為的光(guang)子(zi)(zi)轟(hong)擊在(zai)這(zhe)個物體(ti)上，此時光(guang)子(zi)(zi)能(neng)量(liang)就(jiu)傳遞給電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)，并且是(shi)一(yi)(yi)個光(guang)子(zi)(zi)的全部能(neng)量(liang)一(yi)(yi)次(ci)性地被一(yi)(yi)個電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)所吸收，電(dian)(dian)(dian)(dian)(dian)子(zi)(zi)得到光(guang)子(zi)(zi)傳遞的能(neng)量(liang)后其(qi)狀態就(jiu)會發生(sheng)變化(hua)，從而使受光(guang)照(zhao)射(she)的物體(ti)產生(sheng)相應的電(dian)(dian)(dian)(dian)(dian)效(xiao)應。

這種傳感(gan)器(qi)的正(zheng)常運(yun)作需要(yao)一個反(fan)射器(qi)。基于(yu)高功能預留，它可以(yi)(yi)使用于(yu)任何工(gong)業環(huan)境(jing)。由于(yu)傳感(gan)器(qi)采用了極性光，即便(bian)是鏡(jing)面反(fan)射的物(wu)體也能夠得以(yi)(yi)可靠識(shi)別。

由于設有(you)偏振濾鏡，通(tong)用型鏡反(fan)射傳感(gan)器(qi)(qi)適合檢測(ce)光亮、鍍鉻或反(fan)射的(de)(de)表(biao)面。鏡反(fan)射傳感(gan)器(qi)(qi)使用紅光或激光工作。通(tong)過阻(zu)斷傳感(gan)器(qi)(qi)與反(fan)射器(qi)(qi)之間的(de)(de)光束(shu)來檢測(ce)物體。
