Data Sheet

Description

The HEDS-9710/HEDS-9711 series

is a high performance, low cost,

optical incremental encoder mod-

ule. When operated in conjunction

with either a codewheel or

codestrip, this module detects ro-

tary 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 photodetector

array, the module is extremely tol-

erant to mounting misalignment.

The two-channel analog outputs and

5 V supply input are accessed

through four solder-plated leads

located on 2.54 mm (0.1 inch)

centers.

The standard HEDS-9710/HEDS-

9711 is designed for use with an

Applications

The HEDS-9710/HEDS-9711

provides sophisticated motion

detection at a low cost, making

closed-loop control very cost-

effective. Typical applications

include printers, plotters, copiers,

and office automation equipment.

Note: Agilent Technologies

encoders are not recommended

for use in safety critical

applications, eg., 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 HEDS-9710/HEDS-9711 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 trans-

lates linear motion into analog

outputs.
