Product Description
Product Overview
The AEDR-8000 Encoder series is a reflective surface mount optical encoder designed for motion sensing applications. It offers a direct replacement for the HEDR-8000 series, simplifying migration with matching footprints and height profiles. The encoder utilizes reflective technology with an integrated LED light source and photo-detecting circuitry to translate rotary or linear motion into digital outputs. Its small size and surface mount package make it ideal for high-volume applications where space and weight are critical, such as printers, copiers, and card readers.
