HEDR-5xxx High Resolution Series Three Channel Quick Assembly Encoders Data Sheet Description Features 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. • Three channel encoder A,B and I 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. • No signal adjustment required 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. • 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 • 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 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.

For 2048 cpr option, the recommend range is 11.5 to 13.5 mm. 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.. 3 Absolute Maximum Rating Parameter Value Units Notes Storage Temperature, TS -40 to 100 -20 to 85 °C High temperature option Low temperature option Operating Temperature, TA -40 to 100 -20 to 85 °C High temperature option Low temperature option Supply Voltage, VCC -0.5 to 7 V Output Current per Channel, IOUT Voltage Line Driver 5 20 mA mA Vibration 10G, 55 to 1000 Hz Shaft Axial Play ±0.175 mm Shaft TIR (max.) 0.05 mm Output waveform 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 (PO): 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.
