HEDR-5xxx High Resolution Series
Three Channel Quick Assembly Encoders
Data Sheet
Description
Features
TheAvagoHEDR-5xxxseriesencodersarehigherresolution
replacements for our existing low cost HEDS-5xxx series
three channel optical encoders. These upgraded encoders
now come with resolution of 1200 cycles per revolution
(CPR) to 3600 CPR and are designed for easy assembly.
The base-plate and outer diameter of these encoders are
also compatible with the legacy HEDS-5xxx series, making
them ideal replacements for users who wish to upgrade
due to higher CPR requirements.
• Three channel encoder A,B and I
• Available with ribbon cabling
• Single 5 V supply
• Resolution of 1200 to 3600 CPR
• Available in TTL compatible and line driver options
• Quick assembly
• IP40 rating
• No signal adjustment required
• Compact size: 35 mm (L) × 30 mm (W) × 20 mm (H)
Each encoder contains a codewheel, LED source, detector
and integrated circuitry. As the codewheel rotates, the
detector IC generates two square waves in quadrature
and an index pulse (high state) of 90°e (gated to signal A
and B low), once per each full rotation of the codewheel.
• -40 °C to 100 °C or -20 °C to 85 °C operating temperature
option
Applications
The HEDR-5xxx encoders accommodate shaft diameters
of 2 mm to 8 mm and can operate in high temperature
environments of up to 100 °C.
High volume applications such as industrial printers,
plotters, tape drives, positioning tables ,and automatic
handlers
Note: Avago Technologies encoders are not recommended for use in safety critical applications, e.g., ABS braking
systems, power steering, life support systems and critical care medical equipment. Avago’s products and software are
not specifically designed, manufactured or authorized for sale as parts, components or assemblies for the planning,
construction, maintenance or direct operation of a nuclear facility or for use in medical devices or applications. Customers
are solely responsible, and waive all rights to make claims against Avago or its suppliers, for all losses, damage, expense
or liability in connection with such use. Please contact your local sales representative if clarification is needed.

It is recommended that adhesives (Hernon - Tuffbond™ 317) be applied to the screw-base plate interface to prevent
screw loosening due to CTE effect between screw and plastic at operating temperature..

Direction of Rotation: When the encoder rotates in the counter-clockwise direction (as viewed from the top of the
encoder), channel A will lead channel B. If it rotates in the clockwise direction, channel B will lead channel A.
Index Pulse Width (P ): The number of electrical degrees that an index output is high during one full shaft rotation. This
O
value is nominally 90°e (1/4 cycle) gated to signals A and B, both at low state.
