AR49-M49M-K12H Integrated Circuit Chip 49-bit Absolute Reflective Encoder Module with Screw Termination and 4.5V-5.5V Operating Voltage

AR49-M49M-K12H is an optical absolute encoder module that offers up to 25-bit single-turn (ST) position information and 24-bit multi-turn (MT) counts, providing a combined 49-bit high-resolution output. The ST block consists of a patterned disk, light source, and photosensitive elements to translate mechanical motion into electrical signals. Designed with multiple serial communication protocols, this module features dedicated electronic circuitry for robust signal communication.
