Optical Encoders Market 2017 Global Industry Analysis, Size, Share, Growth, Trends, and Forecast 2025
An optical encoder is an electromechanical device which produces electrical output and is proportionate to the angular state of the input shaft. The optical encoder operates on the principle of optics which converts angular displacementor mechanical rotary motion of an input shaft into a digital signal. A light source from an infra-red or LED is passed through a rotating high-resolution code disk or encoded disk which contains a binary code or grey code. Photo sensors, which could be a phototransistor,...
