CUI Inc has developed a proprietary method of measuring rotational movement by implementing ASIC to detect changes in the frequency of a signal modulated by capactive reactance. Used for years as the key technology in digital callipers, it has been applied to position encoding in the form of the AMT series modular encoder. Compared to the technology most commonly used in rotary encoders today, capacitive encoding holds many advantages over optical encoding. CUI's AMT modular encoder family addresses a number of issues that has plagued traditional optical encoders since their introduction decades ago. This paper highlights the cost and performance advantages of this revolutionary encoder family.
