AEDT-9340 Series

High Temperature 115°C

1250/2500 CPR 6-Channel Commutation Encoder

Data Sheet

Description

The AEDT-9340 optical encoder series are high tempera-

ture six channel optical incremental encoder modules.

When used with a codewheel, these modules detect ro-

tary 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 AEDT-9340 encoder has integrated commutation out-

put channels (U,V,W), two-channel quadrature outputs

(A,B), plus a third channel index output (I). This ungated

index output is a positive index pulse that is generated

once for each full rotation of the codewheel.

The AEDT-9340 encoder is designed for use with a code-

wheel that has an optical radius of 15 mm (0.590 inch) for

1250/2500 CPR, 12.3 mm (0.484 inch) for 1024/2048 CPR

and 12mm (0.472 inch) for 1000/2000 CPR.

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 AEDT-9340 optical encoder provides advanced mo-

tion control detection. The integrated commutation out-

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

Switches. Thus, this makes to encoder ideal for servo mo-

tor applications. Application of the AEDT-9340 solution

also enables the system to be more compact, with a sig-

nificantly reduced alignment time. This is due to the pro-

vision of alignment jigs for easier assembly into housed

encoders. The encoder also provides superior switching

accuracy due to a much lower hysteresis when compared

to a Hall Switches. The commutation signals can easily

be interchanged for Brushless DC motor of different ro-

tor pole-pairs by simply switching to matching pole-pair

codewheels.

Features

• Two-channel quadrature output with ungated index

• Three-channel

• Up to 2500 Cycles Per Revolution (CPR)

• Easy assembly with alignment jig

• Design to fit into circular shaped housing

• Up to 200 kHz frequency response

• -40°C to 115°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

support systems and critical care medical equipment. Please contact

sales representative if more clarification is needed.

... Theory of Operation The AEDT-9340 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 ...
