HEDB-9040 and HEDB-9140
Three Channel Optical Incremental Encoder
Modules Bundle With Codewheel
Data Sheet
Description
The HEDB-9040 and HEDB-9140 series are three channel
optical incremental encoder modules offered with a
codewheel. 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 are
extremely tolerant to mounting misalignment.
The HEDB-9040 and 9140 has two channel quadrature
outputs plus a third channel index output. This index
output is a 90 electrical degree high true index pulse which
is generated once for each full rotation of the codewheel.
The HEDB-9040 is designed for use with a HEDS-6140
codewheel which has an optical radius of 23.36 mm
(0.920 inch). The HEDB-9140 is designed for use with a
HEDS-5140 codewheel which has an optical radius of
11.00 mm (0.433 inch).
The quadrature signals and the index pulse are accessed
through five 0.025 inch square pins located on 0.1 inch
(pitch) centers.
Features
 Two Channel Quadrature Output with Index Pulse
 Resolution from 100 CPR Up To 1024 CPR (Counts Per
Revolution)
 Low Cost
 Easy to Mount
 No Signal Adjustment required
 Small Size
 Operating Temperature: -40°C to 100°C
 TTL Compatible
 Single 5V Supply
Applications
The HEDB-9040 and 9140 provide sophisticated motion
control detection at a low cost, making them ideal for high
volume applications. Typical applications include printers,
plotters, tape drives, and industrial and factory automa-
tion equipment.
Note: Avago 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.
