AEDx-8xxx-xxx
2- or 3-Channel Incremental Encoder Kit with Codewheel
Data Sheet
Description
The AEDx-8xxx comes in an option of two-channel or
three-channel optical incremental encoder kit with code-
wheel integrated in a protective housing. The encoder is
lead free and compliant to the RoHS directive. Each en-
coder kit consists of a collimated LED source and a detec-
tor IC enclosed within a small plastic package.
The AEDx-8xxx optical encoder has two-channel quadra-
ture outputs (A,B) plus a third channel index output (I).
There are three index options available. i.e. ungated, gat-
ed-90 ° and gated-180 ° electrical degree index pulse.
The AEDx-8xxx series optical encoder is designed for use
with motors with shaft diameters of 2mm and up to 5mm.
The quadrature, index and power supplied to the encoder
are accessed through an 8-pin male connector of 1.25 mm
pitch.
The AEDx-8xxx solution enables the servo system to be
more compact. With the aid of alignment jig, the assembly
process will also require less alignment time, thus making
the assembly process much easier for servo motor inte-
gration.
Applications
The AEDx-8xxx provides motion detection for DC servo
motor and closed loop stepper motor feedback system in
the following applications:
• Pick and Place machines
• Semiconductor equipment
• Factory automation equipment
Features
• 3-channel differential output (A,B) with ungated, gated-
90 ° and gated-180 ° index pulse (I)
