The Broadcom AEAT-9000 series are high resolution single turn optical absolute encoders. They are designed to allow design engineers to achieve superior positioning performance in terms of speed and accuracy performance. The modular package enables the encoder to be directly integrated to the motor unlike conventional encoders. As a result design engineers can expect cost savings and better performance of the overall system. The AEAT-9000 series addresses key motor qualities such as position accuracy, speed stability, and bandwidth which determine command-signal response, disturbance rejection capability, power loss, size, and quietness. They are capable of the industry’s best accuracy for an absolute encoder.The AEAT-9000 is a modular absolute encoder that consists of a read head module and a high-precision code disc. The modular design allows for better flexibility to system designers to easily design-in the encoder feedback system.
