AEAT-9000-1GSH1
Ultra-Precision 17-Bit Absolute Encoder

The Avago Technologies 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.

Benefits

Avago’s single turn encoders provide unique positional information for each shaft location. This location is independent from all other locations. In an absolute single turn encoders application, there are several tracks with common centers, and single light sources. As the light passes through the slots on the moving tracks, it creates shadows at intervals. Where a shadow is detected, a low state (0) is created. When the light successfully penetrates the slot a high state (1) is created. The position of the shaft is detected by reading the pattern of 1’s and 0’s. For higher resolution single turn encoders, incremental tracks are added. These tracks enable the interpolation of signals.

Avago’s single turn encoders provide high accuracy read-out for applications which require precise positional information. In addition, these single turn encoders’ use of the SSI non-proprietary serial communication protocol means that these single turn encoders can match most applications’ output requirements.

Avago's absolute single turn encoders come in a 13-bit and 16-bit resolution package to cater to the needs of a range of applications in the factory and industrial automation industry such as robotic arms, valve controls, test and measurement equipment, etc.
