The SEM90-HN050AK22 is a high-resolution absolute rotary encoder from the SICK SEM90 series, designed for direct motor integration with large hollow shafts. It uses the HIPERFACE® digital interface, allowing both power and data to be transmitted through a single cable, simplifying wiring and reducing system complexity. Its compact, bearing-free design ensures wear-free operation and high reliability, making it ideal for precise positioning in limited-space installations.
