Description

The HEDS-9000 Options T and U

and the HEDS-9100 Options B

and J are high resolution two

channel rotary incremental

encoder modules. These options

are an extension of our popular

HEDS-9000 and HEDS-9100

series. When used with a code-

wheel, these modules detect

relative rotary position. The

HEDS-9200 Option 300 and 360

are high resolution linear encoder

modules. When used with a

HEDS-9000/9100/9200

Extended Resolution

Series

codestrip, these modules detect

relative linear position.

These modules consist of a lensed

Light Emitting Diode (LED)

source and detector IC enclosed

in a small C shaped plastic

package. Due to a highly

collimated light source and

unique photodetector array, these

modules provide a highly reliable

quadrature output.

The HEDS-9000 and HEDS-9100

are designed for use with

codewheels which have an optical

radius of 23.36 mm and 11 mm

respectively. The HEDS-9200 is

designed for use with a linear

codestrip.

These components produce a two

channel quadrature output which

can be accessed through five

0.025 inch square pins located on

0.1 inch centers.

The resolution of the HEDS-9000

Options T and U are 2000 and

2048 counts per revolution

respectively. The HEDS-9100

Options B and J are 1000 and

1024 counts per revolution

respectively. The HEDS-9200

Option 300 and 360 linear

encoder modules have resolutions

of 300 and 360 lines per inch.

Consult local Agilent sales

representatives for other

resolutions.

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.

ESD WARNING: NORMAL HANDLING PRECAUTIONS SHOULD BE TAKEN TO AVOID STATIC

DISCHARGE.
