ASM位置傳感器產品分類及工作原理
美國ASM位置傳感器用來測量機器人自身位置的傳感器。位置傳感器可分為兩種，直線位移傳感器和角位移傳感器。其中直線位移傳感器常用的有直線位移定位器等，具有工作原理簡單、測量精度高、可靠性強的特點；角位移傳感器則可選旋轉式電位器，具有可靠性高、成本低的優點。角位移器還可使用光電編碼器，有增量式與絕對式兩種形式。其中增量式碼盤在機器人控制系統中得到了廣泛的應用。
美國ASM位置傳感器工作原理
信號盤安裝在發光二極管(LED)與光敏晶體管(或光敏二極管)之間。當信號盤上的透光孔旋轉到LED與光敏晶體管之間時，LED發出的光線就會照射到光敏晶體管上，此時光敏晶體管導通，其集電極輸出低電平(0．1～O．3V)；當信號盤上的遮光部分旋轉到LED與光敏晶體管之間時，LED發出的光線就不能照射到光敏晶體管上，此時光敏晶體管截止，其集電極輸出高電平(4．8～5．2V)。
如果信號盤連續旋轉，透光孔和遮光部分就會交替地轉過LED而透光或遮光，光敏晶體管集電極就會交替地輸出高電平和低電平。當傳感器軸隨曲軸和配氣凸輪軸轉動時，信號盤上的透光孔和遮光部分便從LED與光敏晶體管之間轉過，LED發出的光線受信號盤透光和遮光作用就會交替照射到信號發生器的光敏晶體管上，信號傳感器中就會產生與曲軸位置和凸輪軸位置對應的脈沖信號。
