HEDS-9000/9100
Two Channel Optical Incremental Encoder Modules
Data Sheet
Description
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.
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.
For the HEDS-9100, standard resolutions between 96
CPR and 512 CPR are available for use with a HEDS-5120
codewheel or equivalent.
Features
• 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
• 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.
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.

Definitions
Count (N): The number of bar and window pairs or counts
per revolution (CPR) of the codewheel.
1 Shaft Rotation
= 360 mechanical degrees,
= N cycles.
1 cycle (C) = 360 electrical degrees (°e),
= 1 bar and window pair.
Pulse Width (P): The number of electrical degrees that
an output is high during 1 cycle. This value is nominally
180°e or 1/2 cycle.
Pulse Width Error (∆P): The deviation, in electrical degrees
of the pulse width from its ideal value of 180°e.
State Width (S): The number of electrical degrees between a
transition in the output of chann el A and the neighboring
transition in the output of channel B.There are 4 states per
cycle, each nominally 90°e.
State Width Error (∆S): The deviation, in electrical degrees,
of each state width from its ideal value of 90°e.
Phase (φ): The number of electrical degrees between the
center of the high state of channel A and the center of
the high state of channel B. This value is nominally 90°e
for quadrature output.
Phase Error (∆φ): The deviation of the phase from its ideal
value of 90°e.
Direction of Rotation: When the codewheel rotates in the
direction of the arrow on top of the module, channel A will
lead channel B. If the codewheel rotates in the opposite
direction, channel B will lead channel A.
