Broadcom Incremental Incremental Encoder, Push Pull Signal

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-9040 and HEDS-9140 series are three channel optical incremental encoder modules. When used with a code wheel, these low cost modules detect rotary position. Each module consists of a lensed LED source and a detector IC enclosed in a small plastic package. Due to a highly collimated light source and a unique photodetector array, these modules provide the same high performance found in the HEDS-9000/9100 two channel encoder family.
