WL260-S270施(shi)克光電(dian)傳感器分為以(yi)下4種：

⑴槽型光電傳感器

把一個(ge)(ge)光(guang)發(fa)射(she)器(qi)和一個(ge)(ge)接(jie)(jie)收(shou)器(qi)面對面地裝在(zai)一個(ge)(ge)槽(cao)的兩(liang)側組成(cheng)槽(cao)形光(guang)電。發(fa)光(guang)器(qi)能發(fa)出(chu)紅(hong)外光(guang)或可見(jian)光(guang)，在(zai)無阻(zu)情況下(xia)光(guang)接(jie)(jie)收(shou)器(qi)能收(shou)到光(guang)。但(dan)當被檢測(ce)物體從槽(cao)中通過時(shi)，光(guang)被遮擋，光(guang)電開關便動(dong)(dong)作，輸出(chu)一個(ge)(ge)開關控(kong)制(zhi)(zhi)信號，切斷(duan)或接(jie)(jie)通負載電流，從而完成(cheng)一次控(kong)制(zhi)(zhi)動(dong)(dong)作。槽(cao)形開關的檢測(ce)距離因為受整體結構的限制(zhi)(zhi)一般(ban)只有(you)幾(ji)厘米。

⑵對射型光電傳感器

若把發光(guang)(guang)器(qi)(qi)(qi)和(he)收光(guang)(guang)器(qi)(qi)(qi)分離(li)開，就(jiu)可使(shi)檢(jian)測距離(li)加大，一個發光(guang)(guang)器(qi)(qi)(qi)和(he)一個收光(guang)(guang)器(qi)(qi)(qi)組成對射(she)分離(li)式(shi)光(guang)(guang)電(dian)(dian)開關(guan)，簡稱對射(she)式(shi)光(guang)(guang)電(dian)(dian)開關(guan)。對射(she)式(shi)光(guang)(guang)電(dian)(dian)開關(guan)的檢(jian)測距離(li)可達幾米乃至幾十米。使(shi)用對射(she)式(shi)光(guang)(guang)電(dian)(dian)開關(guan)時(shi)把發光(guang)(guang)器(qi)(qi)(qi)和(he)收光(guang)(guang)器(qi)(qi)(qi)分別(bie)裝(zhuang)在檢(jian)測物(wu)(wu)通過路徑的兩側(ce)，檢(jian)測物(wu)(wu)通過時(shi)阻擋(dang)光(guang)(guang)路，收光(guang)(guang)器(qi)(qi)(qi)就(jiu)動(dong)作輸出一個開關(guan)控(kong)制信號。

⑶反光板型光電開關

SICK光(guang)(guang)(guang)(guang)(guang)電傳感(gan)器(qi)把發(fa)(fa)光(guang)(guang)(guang)(guang)(guang)器(qi)和(he)收(shou)光(guang)(guang)(guang)(guang)(guang)器(qi)裝(zhuang)入同一(yi)個(ge)裝(zhuang)置內(nei)，在前方裝(zhuang)一(yi)塊反(fan)光(guang)(guang)(guang)(guang)(guang)板(ban)，利用反(fan)射(she)原理完成光(guang)(guang)(guang)(guang)(guang)電控(kong)制作(zuo)用，稱為(wei)反(fan)光(guang)(guang)(guang)(guang)(guang)板(ban)反(fan)射(she)式(或反(fan)射(she)鏡(jing)反(fan)射(she)式)光(guang)(guang)(guang)(guang)(guang)電開關。正常情況(kuang)下，發(fa)(fa)光(guang)(guang)(guang)(guang)(guang)器(qi)發(fa)(fa)出的光(guang)(guang)(guang)(guang)(guang)源(yuan)被(bei)反(fan)光(guang)(guang)(guang)(guang)(guang)板(ban)反(fan)射(she)回來再(zai)被(bei)收(shou)光(guang)(guang)(guang)(guang)(guang)器(qi)收(shou)到;一(yi)旦被(bei)檢(jian)測物(wu)擋住(zhu)光(guang)(guang)(guang)(guang)(guang)路，收(shou)光(guang)(guang)(guang)(guang)(guang)器(qi)收(shou)不(bu)到光(guang)(guang)(guang)(guang)(guang)時，光(guang)(guang)(guang)(guang)(guang)電開關就動作(zuo)，輸出一(yi)個(ge)開關控(kong)制信號(hao)。

⑷擴散反射(she)型光(guang)電開關

擴散(san)反射(she)(she)(she)型光電開關的檢(jian)測頭里也裝有一個(ge)(ge)發光器(qi)(qi)和一個(ge)(ge)收(shou)(shou)光器(qi)(qi)，但擴散(san)反射(she)(she)(she)型光電開關前方沒有反光板。正常情(qing)況下(xia)發光器(qi)(qi)發出的光收(shou)(shou)光器(qi)(qi)是找不到(dao)的。在檢(jian)測時(shi)(shi)，當檢(jian)測物通過時(shi)(shi)擋住(zhu)了光，并把光部分反射(she)(she)(she)回來，收(shou)(shou)光器(qi)(qi)就(jiu)收(shou)(shou)到(dao)光信(xin)號，輸出一個(ge)(ge)開關信(xin)號。
