Description

The HEDS-9202 is a high-performance, low-cost, op-

tical incremental encoder module. When operated in

conjunction with either a codewheel or codestrip, this

module detects rotary or linear position. The encoder

module consists of a lensed LED source and a detector

IC enclosed in a small C-shaped plastic package. Due

to a highly collimated light source and a unique photo-

detector array, the module is extremely tolerant to

mounting misalignment.

The two channel analog outputs and 5 V supply input

are accessed through five 0.025 inch square pins

located on 0.1 inch centers. The standard HEDS-9202

is designed for use with an appropriate optical

radius codewheel, or linear codestrip.

Applications

The HEDS-9202 provides sophisticated motion detec-

tion at a low cost, making closed-loop control very

cost-effective. Typical applications include printers,

plotters, copiers, and office automation equipment.

Note: Avago Technologies’ encoders are not recom-

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

braking systems, power steering, life support systems,

and critical care medical equipment. Please contact

sales representatives if more clarification is needed.

Theory of Operation

The HEDS-9202 is a C-shaped emitter/detector mod-

ule. Coupled with a codewheel, it translates rotary

motion into a two-channel analog output. Coupled

with a codestrip, it translates linear motion into analog

outputs. The module contains a single Light Emitting

Data Sheet

Diode (LED) as its light source. The light is collimated

into a parallel beam by means of a single lens located

directly over the LED. Opposite the emitter is the

integrated detector circuit. This IC consists of multiple

sets of photodetectors and the signal processing cir-

cuitry necessary to produce the analog waveforms.

The codewheel/codestrip moves between the emitter

and detector, causing the light beam to be interrupted

by the pattern of spaces and bars on the codewheel/

codestrip. The photodiodes which detect these inter-

ruptions are arranged in a pattern that corresponds to

the radius and count density of the codewheel/codestrip.

These detectors are also spaced such that a light p e -

riod on one pair of detectors corresponds to a dark

period on the adjacent pair of detectors. The photo-

diode outputs are fed through the signal processing
