Three Channel Optical
Incremental Encoder Modules
Data Sheet
Description
The HEDT-9040 and HEDT-9140 are high temperature
three channel optical incremental encoder modules.
When used with a codewheel, these low cost modules
detect rotary 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 photodetector array, these modules provide the
same high performance found in the HEDS-9040/9140
three channel encoders.
The HEDT-9040 and 9140 have Block Diagram two channel
quadrature outputs plus a third channel index output.
This index output is a 90 electrical degree high true index
pulse.
The HEDT-9040 is designed for codewheels which have an
optical radius of 23.36 mm (0.920 in.). The HEDT-9140 is
designed for codewheels which have an optical radius of
11.00 mm (0.433 in.).
The quadrature signals and the index pulse are accessed
through five 0.025 inch square pins located on 0.1 inch
centers.
Resolutions between 360 and 1024 counts per revolution
are available. Consult local Avago sales representatives for
other resolutions.

Applications
The HEDT-9040 and 9140 provide high temperature
motion control detection at a low cost, making them
suitable for industrial applications.
Note: Avago Technologies encoders are not recommend-
ed for use in safety critical applications. Eg. ABS braking
systems, power steering, life support systems and critical
care medical equipment. Please contact sales representa-
tive if more clarification is needed.
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.
