Features
Description
• Gray or binary code options
• High or low power source options
• IP 65 rating
The AEAS-71AC-xxxxB absolute encoder is a feed-
back device that has the capabilityto generate a unique
binary ‘word’ for each encoder shaft position. The
AEAS-71AC-xxxxB also has the unique feature of
being able to provide positional information upon
power up without the need for codewheel movement,
unlike incremental encoders, which need codewheel
movement to provide positional information.
• 50 mm package diameter
• 8 bits and 10 bits resolution
• Hollow shaft with 8 mm inside diameter
• The package comes with 2 m long cable
Each absolute encoder from the AEAS-71AC-xxxxB
consists ofa lensed LED(Light Emitting Diode) source,
an integrated circuit with detectors and output cir-
cuitry, and a special multi-track glass codewheel that
rotates between the emitter and detector IC. These 3
main components are contained within a strong metal
housing fitted with bearings to produce an IP rated
encoder capable of working in very wet and dusty
conditions. Models with IP65 ratings have sealed
bearings.
Applications
• Tool changers and axis control for machine tools
• Robotics
• Telescopes and antennas
• Rotary and X - Y positioning tables
• Medical scanners

Theory of Operation
The AEAS-71AC-xxxxB is a single-
turn, low-cost, and compact
absolute encoder which uses
optical technology to provide
absolute positioning information.
The light is collimated into a
parallel beam by means of a lens
which is built into the LED
housing. This parallel beam goes
through the Fixed Slit that creates
a certain light pattern, due to its
pattern of slots, which will fall onto
the code-wheel. The movement of
the code-wheel between LED and
Photo detector, causes the light
pattern (from the Fixed Slit) to be
further interrupted by the pattern
of spaces and bars on the
The AEAS-71AC-xxxxB consists of
a LED, Fixed Slit, Codewheel
(Rotating Disc) and Photodiode IC.
By using these four main compo-
nents, the AEAS-71AC-xxxxB is
able to produce signals in either
binary or gray output form. These
signals provide to the designer a
unique code for each position that
the codewheel is in.
codewheel. This final light pattern
from the codewheel is then
detected by the Photodiode IC
where its signals are fed through
