AEAT-9000-1GSH1 (Basic Option)
Ultra-precision 17-Bit Absolute Single Turn Encoder
Data Sheet
Description
Avago Technologies’ AEAT-9000 series are high resolu-
tion single turn optical absolute encoders. The 17-bit
AEAT-9000 encoder code disc consists of 13 pairs of dif-
ferential absolute tracks and 2 pairs of sinusoidal tracks to
perform 4 bits interpolation. In addition, the encoder in-
corporates photo detectors for electrical alignment on the
radial and tilt. AEAT-9000 also comes with 2 channel incre-
mental output with the basic of 2048 counts per rotation.
The AEAT-9000 is a modular absolute encoder that consists
of a read head module and a high-precision code disc
[(HEDG-9000-H13 & HEDG-9000-H14) which is ordered
separately]. The modular design allows for better flex-
ibility to system designers to easily design-in the encoder
feedback system.
Features
