HEDS-9000/9100
Two Channel Optical Incremental Encoder Modules
Data Sheet
Description
Features
The HEDS-9000 and the HEDS-9100 series are high
performance, low cost, optical incremental encoder
modules. When used with a codewheel, these mod-
ules detect rotary position. The modules consist 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 unique photodetector array, these mod-
ules are extremely tolerant to mounting misalignment.
• High performance
• High resolution
• Low cost
• Easy to mount
• No signal adjustment required
• Small size
• -40°C to 100 °C operating temperature
• Two channel quadrature output
• TTL compatible
The two channel digital outputs and the single 5 V sup-
ply input are accessed through five 0.025 inch square
pins located on 0.1 inch centers.
Standard resolutions for the HEDS-9000 are 500 CPR
and 1000 CPR for use with a HEDS-6100 codewheel or
equivalent.
• Single 5 V supply
Applications
The HEDS-9000 and 9100 provide sophisticated mo-
tion detection at a low cost, making them ideal for high
volume applications. Typical applications include print-
ers, plotters, tape drives, and factory automation equip-
ment.
For the HEDS-9100, standard resolutions between 96
CPR and 512 CPR are available for use with a HEDS-5120
codewheel or equivalent.
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 represen-
tative if more clarification is needed.
ESD WARNING: NORMAL HANDLING PRECAUTIONS SHOULD BE TAKEN TO AVOID STATIC DISCHARGE.
Theory of Operation
The codewheel rotates between the emitter and detec-
tor, causing the light beam to be interrupted by the pat-
tern of spaces and bars on the codewheel. The photo-
diodes which detect these interruptions are arranged in
a pattern that corresponds to the radius and design of
the odewheel. These detectors are also spaced such that
a light period on one pair of detectors corresponds to a
dark period on the adjacent pair of detectors. The photo-
diode outputs are then fed through the signal process-
ing circuitry resulting in A, A, B, and B. Two comparators
receive these signals and produce the final outputs for
channels A and B. Due to this integrated phasing tech-
nique, the digital output of channel A is in quadrature
with that of channel B (90 degrees out of phase).
The HEDS-9000 and 9100 are C-shaped emitter/detec-
tor modules. Coupled with a codewheel, they translate
the rotary motion of a shaft into a two-channel digital
output.
As seen in the block diagram, each module contains a
single Light Emitting Diode (LED) as its light source. The
light is collimated into a parallel beam by means of a
single polycarbonate 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 circuitry necessary to product the
digital waveforms.

Derating Curves over Extended Operating Frequencies (HEDS-9000/9100)
Below are the derating curves for state, duty, phase and VOH over extended operating frequencies of up to
240 kHz (recommended maximum frequency is 100 kHz). The curves were derived using standard TTL load.
–40°C operation is not feasible above 160 kHz because VOH will drop below 2.4 V (the minmum TTL for logic state high)
beyond that frequency.
