AEDB-9340 Series

1250/2500 CPR Commutation Encoder Modules

with Codewheel

Data Sheet

Description

The AEDB-9340 optical encoder series are six-channel

optical incremental encoder modules with codewheel.

The encoder is compliant to RoHS directive and had

been declared as a lead free product. When used with

codewheel, these modules detect rotary position. Each

module consists of a collimated LED source and detector

IC enclosed within a small plastic package. Due to

highly collimated light source and unique photo detec-

tor array designs, these modules are extremely tolerant

to mounting misalignment.

The AEDB-9340 optical encoder has integrated commu-

tation output (U, V, W), two-channel quadrature outputs

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

index output is a positive index pulse that is generated

once for each full rotation of the codewheel.

The AEDB-9340 series optical encoder is designed for

use with a codewheel 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 12 mm (0.472 inch) for 1000/

2000 CPR.

The quadrature, index, commutation signals and power

supplied to encoder are accessed through eight

0.46 mm square male connector pins located on 1.27 mm

(pitch).

The AEDB-9340 optical encoder provides advanced

motion control detection with integrated commutation

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

by Hall Switches, thus making it ideal for servo motor

application. With the AEDB-9340 solution, the system will

be more compact, have reduced alignment time with

usage of alignment jig, thus making assembly process

much easier for housed encoder integration. It has

superior switching accuracy due to much lower

hysteresis when compared to a Hall Switches. The com-

mutation signals can be generated for Brushless DC

motor of different rotor pole-pairs by simply changing

with matching pole-pair codewheel.

Features

• Two-channel quadrature output with ungated index

• Three-channel integrated commutation output (U, V, W)

• Up to 2500 Cycles Per Revolution (CPR)

• Easy assembly with alignment jig

• Designed to fit into circular shaped housing

• Up to 150 kHz frequency response

• –10 C to 85 C operating temperature

• TTL compatible

• Single 5 V supply

• Integrated feedback device for Brushless DC Motor

Applications

Typical applications include industrial printers, plotters,

tape drives, and industrial and factory automation

equipment.

Note: Avago Technologies encoders are not recommended

for use in safety critical applications, e.g., ABS braking

systems, power steering, life support systems and critical

care medical equipment. Please contact sales representative

if more clarification is needed.
