AEDS-9240 Series

360/720 CPR Commutation Encoder Module

Data Sheet

Description

The AEDS-9240 optical encoder is a six channel optical

incremental encoder module. When used with a code-

wheel, this encoder detects rotary position. Each module

consists of a lensed LED source and a detector IC enclosed

in a small plastic package. Due to a highly collimated light

source and a unique photo detector array, these modules

are extremely tolerant to mounting misalignment.

The AEDS-9240 encoder is designed with integrated com-

mutation output channels (U,V,W), two-channel quadra-

ture outputs (A,B), plus a third channel ungated index

output (I). This ungated index output is a positive index

pulse that is generated once for each full rotation of the

codewheel.

The AEDS-9240 encoder is designed for use with a code-

wheel that has an optical radius of 19.00 mm (0.748 inch)

to obtain an optimum 360/720 CPR (count per revolution)

resolution.

The quadrature, index, commutation signals and power

supplied to encoder are accessed through eight 0.46mm

square male connector pins located on 1.27mm pitch.

The AEDS-9240 optical encoder also provides advanced

motion control detection. Its integrated commutation

outputs (U,V, and W) is equivalent to those produced by

Hall Switches. Thus, this makes the encoder ideal for servo

motor applications. Application of the AEDS-9240 en-

coder also enables motor systems to be more compact.

In addition, the provision of alignment jigs enables a sig-

nificantly reduced production time and ease of assembly

into housed encoders. The encoder also provides superior

switching accuracy due to a much lower hysteresis when

compared to Hall Switches. Its commutation signals can

easily be interchanged for Brushless DC motor of different

rotor pole-pairs by simply switching to matching pole-

pair codewheels.

Features

• Two-channel quadrature output with ungated index

• Three-channel integrated commutation Output (UVW)

• 360/720 Cycle Per Revolution (CPR)

• Easy assembly with alignment jig

• Design to fit into circular shaped housing

• Up to 150 kHz frequency response

• -40°C to 100°C operating temperature

• TTL Compatible

• Single 5V Supply

• Integrated feedback device for Brushless DC Motor

• RoHS Compliant

Applications

Typical applications include industrial printers, plotters,

tape drives, industrial and factory automation equip-

ment.

Note:

Avago Technologies encoders are not recommended for use in safety

critical application, e.g., ABS braking systems, power steering, life sup-

port systems and critical care medical equipment. Please contact sales

representative if more clarification is needed.

... Theory of Operation The AEDS-9240 optical encoder is an emitter/detector module. Coupled with a codewheel, these modules trans- late the rotary motion of a shaft into a six-channel digital output. The modules contain a single Light Emitting Diode (LED) as its light source. The light is collimated into a parallel beam by means of a single polycarbonate lens located di- rectly over the LED ...
