Broadcom 5V dc Optical Encoder Hollow Shaft

This range of motion control optical encoders, by Avago Technologies, is available in two and three channel output options. These incremental encoders utilize optical technology for motion control. Incremental encoder devices provide position feedback for incremental counts. Where the feedback signal is always referenced to a start or home position, an incremental encoder provides a uniquely defined, relative position. Avago Technologies offer both optical reflective incremental encoders and optical transmissive incremental encoders. These devices are available as encoder modules for user integration or as complete housed or kit incremental encoders. This range of optical encoders provides accurate positioning and velocity sensing for a variety of applications.

Possible applications include:
printers
copiers
scanners
servo and stepper motor feedback systems
robotic arms
wafer-handling machines

The Broadcom HEDS-5640 are high performance, low cost, two and three channel optical incremental encoders. These encoders offer high reliability, high resolution, and easy assembly. Each encoder contains a lensed LED source, an integrated circuit with detectors and output circuitry, and a code wheel which rotates between the emitter and detector IC.
