ASM位置传感器产品分类及工作原理
美国ASM位置传感器用来测量机器人自身位置的传感器。位置传感器可分为两种，直线位移传感器和角位移传感器。其中直线位移传感器常用的有直线位移定位器等，具有工作原理简单、测量精度高、可靠性强的特点；角位移传感器则可选旋转式电位器，具有可靠性高、成本低的优点。角位移器还可使用光电编码器，有增量式与绝对式两种形式。其中增量式码盘在机器人控制系统中得到了广泛的应用。
美国ASM位置传感器工作原理
信号盘安装在发光二极管(LED)与光敏晶体管(或光敏二极管)之间。当信号盘上的透光孔旋转到LED与光敏晶体管之间时，LED发出的光线就会照射到光敏晶体管上，此时光敏晶体管导通，其集电极输出低电平(0．1～O．3V)；当信号盘上的遮光部分旋转到LED与光敏晶体管之间时，LED发出的光线就不能照射到光敏晶体管上，此时光敏晶体管截止，其集电极输出高电平(4．8～5．2V)。
如果信号盘连续旋转，透光孔和遮光部分就会交替地转过LED而透光或遮光，光敏晶体管集电极就会交替地输出高电平和低电平。当传感器轴随曲轴和配气凸轮轴转动时，信号盘上的透光孔和遮光部分便从LED与光敏晶体管之间转过，LED发出的光线受信号盘透光和遮光作用就会交替照射到信号发生器的光敏晶体管上，信号传感器中就会产生与曲轴位置和凸轮轴位置对应的脉冲信号。
