P1-P3P4-P6P7-P8
AEDT-981x
High Temperature 115°C, High Resolution,
Three Channels Optical Incremental Encoder Modules
Data Sheet
Description
Avago Technologies' AEDT-981x encoders are industrial
grade high temperature (-40 to 115°C) rating three chan-
nel optical incremental encoder modules building on the
Avago legacy HEDS-9140 series.
Using an Avago developed opto ASIC with the built-in In-
terpolator circuit, AEDT-981x encoders enable wide reso-
lution range from 2000 to 5000 count per revolution with
the rotary codewheel of 11mm optical radius, oering a
high resolution yet compact solution.
With the opto-ASIC’s built-in automatic LED brightness
regulation technique, the encoder current consumption
can be signicantly lowered (Typ. Icc: 20mA) while main-
taining optimal encoder performance across spatial cor-
ners. This LED brightness control feature also enables op-
timal LED current control hence LED life can signicantly
pro-longed.
With the state of the art opto-mechanical design, AEDT-
981x oers excellent spatial play of ∅ 0.40mm and code
wheel gap range of ±150um. This allows great exibility
and ease of installation to the user.
Inheriting the indefeasible integrity in product robust-
ness, repeatability and reliability, AEDT-981x series are de-
signed for wide market employment withstanding wide
application requirement and environment demand.
Features
• -40°C to 115°C Operating Temperature
• Two Channel Quadrature Output with Index Pulse
• Single ended output with ±5mA output sink/source
current per channel
• Suitable for Industrial Applications
• Resolution up to 5000 Counts per Revolution
• Low Power Consumption (Typical Icc: 20 mA)
• No Signal Adjustment Required
• Pin Compatible to legacy HEDS-9xxx Series
• Spatial play tolerance of ∅ 0.40mm
• Allows motor shaft axial play of ±0.15mm
• ESD Immunity HBM 4kV (JESD22-A114D)
Applications
The AEDT-981x series provide high temperature motion
control detection with ease of installation, making them
suitable for wide range of commercial & industrial appli-
cations.
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.
Note: Avago Technologies encoders are not recommend-
ed for use in safety critical applications. Eg. ABS braking
systems, power steering, life support systems and critical
care medical equipment. Please contact sales representa-
tive if more clarication is needed.

Mounting Considerations with Aligning Pin
The AEDT-981X can be mounted using xed aligning pins on the motor base. For this conguration, Side A or B can be
used as the mounting plane as shown.
