The Avago AEDT-981x is a series of high resolution 3-channel optical incremental encoder modules designed for robust, high precision motion control applications. Building upon Avago's market-proven HEDS-914x series, the AEDT-981x features a built-in interpolator supporting a wide range of encoding resolution from 1,000 to 5,000 counts per revolution (CPR) using a codewheel of 11mm optical radius. The module series is industrial grade with operating temperature from -40 °C to +115 °C. With built-in LED brightness autoregulation, the AEDT-981x maintains an optimal encoder performance across spatial corners with low current consumption. The AEDT-981x offers a wide spatial error tolerance of 0.4 mm and codewheel gap range of +/-0.15 mm, providing ease of motor shaft alignment and enhancing photo detector signal integrity.
