High-Resolution Optical Encoder Module AEDR-8723-102 by Broadcom

The AEDR-8723-102 from Broadcom represents a significant advancement in optical encoder technology, offering a blend of high resolution, miniaturization, and reliability for demanding motion control applications. As a reflective surface-mount encoder module, it integrates a photo detector, an infrared LED light source, and signal processing circuitry into a single, compact package. This integration is critical for modern designs where space-saving and high performance are paramount.

A key feature of this module is its impressive high resolution of 1024 pulses per revolution (PPR), achieved through quadrature outputs. This fine resolution provides exceptional positional accuracy and velocity control, making it ideal for applications requiring precise motion feedback, such as in robotics, CNC machines, medical instrumentation, and high-end office automation equipment. The quadrature outputs (Channel A and Channel B) allow the system to not only determine the position but also the direction of rotation, while the optional index pulse (Channel I) provides a reference mark for absolute positioning.

The AEDR-8723-102 operates on the principle of reflective technology. It detects changes in reflectivity from a codewheel or codestrip, which is printed with alternating light and dark lines. This design eliminates the need for a separate lens system, contributing to its remarkably small form factor and robustness against environmental contaminants. Furthermore, it is designed for easy integration into automated assembly processes, featuring a surface-mount package that simplifies PCB design and manufacturing.

Broadcom has engineered this module for exceptional reliability and signal stability. It operates effectively across a wide voltage range and is capable of high-speed motion detection, supporting applications with rapidly changing velocities. The internal circuitry ensures clean digital waveforms, minimizing errors and providing a robust signal even in electrically noisy environments.

ICGOODFIND: The Broadcom AEDR-8723-102 optical encoder module is a premier solution for engineers seeking to enhance system performance with a component that delivers high resolution in an ultra-compact, reliable, and easy-to-integrate package.
