HEDC-55xx/HEDC-56xx Two or Three Channel Quick Assembly Encoders With Connector Latch Data Sheet Description Features The HEDC-5xxx-xxx, while similar to the industry standard Available in two or three channel encoder A, B and I HEDS-5xxx kit encoder, provides a connector latch on Latching connector design the cover housing to improve connector retention. This Single 5 V supply device is built upon the HP/Agilent/Avago HEDS-9000 series encoder module, and provides the same perfor- Resolution of up to 1024 CPR mance, low cost, high reliability, high resolution, and ease TTL compatible, with single ended or differential of assembly customers have come to expect. output. Each encoder contains a lensed LED source, an integrated Quick assembly circuit with detectors and output circuitry. A codewheel No signal adjustment required (disk) which rotates between the emitter and detector IC Small size -40 C to 100 C operating temperature generates two square waves in quadrature. Three channel units include an index pulse (high state) of 90e, which is Applications generated once for each full rotation. High volume applications such as printers, plotters, tape HEDC-5xxx-xxx provides resolutions from 50 to 1024 CPR, drives, textile machines, positioning tables and also and accommodating shaft diameters from 2 mm to 8 mm. automatic handlers among others. This kit encoder may be quickly and easily mounted to a motor. The electrical interface is through five (single Note: Avago Technologies encoders are not recommended for use in ended) or ten (differential versions) 0.025 inch square safety critical applications, e.g., ABS braking systems, power steering, life support systems and critical care medical equipment.
