Optoelectronic angle of rotation sensor |
摘要 |
A sensor for determining the angular position of a device includes a code disk and a sensor array. The code disk moves in a movement direction in response to rotational movement of the device. The code disk has a digital code including two sets of code tracks extending along the length of the code disk. The corresponding tracks of each track set are spaced apart from one another across the width of the code disk. The sensor array is arranged adjacent to one side of the code disk and across the width of the code disk for sensing the tracks as the other side of the code disk is illuminated to determine the angular position of the device. The sensor provides a reliable indication of the angular position of the device if the digital code is partially contaminated with debris as the digital code contains two sets of corresponding tracks. |
