Avago (Basic Option): Ultra-Precision Absolute Encoder,17-Bit (AEAT-9000 Series) Avago (Basic Option): Ultra-Precision Absolute Encoder,17-Bit (AEAT-9000 Series)

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.

Features

  • 17-bit absolute single turn output (131072 absolute positions over 360°)

  • 2048 CPR A/B channel incremental digital output

  • Interface output will be SSI (2wire SSI / 3wire SSI)

  • On-chip interpolation and code correction compensate for mounting tolerance

  • Selectable direction for Up/Down position counter

  • Electrical alignment output for tilt and locate

  • Built-in monitor track for monitoring of LED light level

  • Error output for LED degradation

  • -40 to 115°C operating temperature

Applications

  • Rotary applications up to 17 bits/360° absolute position

  • Integration into servo motors

  • Industrial and maritime valve control

  • High precision test and measurement machines

  • Industrial and factory automation equipment

  • Textile, woodworking & packaging machineries

  • Nacelle & blades control in wind turbine

Benefits

  • Feedback device generates unique binary 'word' for each encoder shaft position

  • Provides positional information instantly upon power up

  • Ideal for space constrained applications

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.
