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

value is nominally 90°e (1/4 cycle) gated to signals A and B, both at low state.
