HEDR-5xxx High Resolution Series

Three Channel Quick Assembly Encoders

Data Sheet

Description

The Avago HEDR-5xxx series encoders are higher resolution

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.

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.

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. Shielded cable (single

ended or line driver) and ribbon cable (line driver) pin-out

connectivity options are available.

Features

• Three channel encoder A,B and I

• Available with option of ribbon or shielded 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)

• -40 °C to 100 °C or -20 °C to 85 °C operating temperature

option

Applications

High volume applications such as industrial printers,

plotters, tape drives, positioning tables ,and automatic

handlers
