AEAT-9000-1GSH0 (Full Option) Ultra-precision 17-Bit Absolute Single Turn Encoder Data Sheet Description Features Avago Technologies AEAT-9000 series are high resolution 17-bit absolute single turn output (131072 absolute single turn optical absolute encoders. They are designed positions over 360) to allows users to achieve superior positioning perfor- 2 channel true differential Sine/Cosine outputs with mance in terms of speed and accuracy performance. The 2048 cycles per revolution modular package enables the encoder to be directly in- 2048 CPR A/B channel incremental digital output tegrated to the motor unlike conventional encoders. As a result, users can expect cost savings and better perfor- Interface output is SSI (2wire SSI / 3wire SSI) with RS485 mance of the overall system. line transceiver or single ended option On-chip interpolation and code correction compensate The AEAT-9000 addresses key qualities that are motor- for mounting tolerance related such as position accuracy, speed stability, and bandwidth which determine command-signal response, Selectable direction for Up/Down position counter disturbance rejection capability, power loss, size, and Electrical alignment output for tilt and locate quietness. They are capable of the industrys best accuracy Built-in monitor track for monitoring of LED light level for an absolute encoder. Error output for LED degradation The AEAT-9000 is a modular absolute encoder that consists of a read head module and a high-precision code disc -40 to 115 C operating temperature (HEDG-9000-H13 & HEDG-9000-H14) which is ordered Applications separately . The modular design allows for better flex - ibility to system designers to easily design-in the encoder Typical applications include feedback system.
