Avago Technologies Codewheels for Optical Encoder Modules
Product Overview
Avago Technologies offers a versatile range of codewheels designed for use with their HEDS-9000, HEDS-9100, HEDS-9040, and HEDS-9140 series optical encoder modules. Available in Glass, Film, and Metal, these codewheels cater to diverse environments, applications, and budgets. They provide resolutions from 96 Counts Per Revolution (CPR) up to 2048 CPR, supporting both two and three-channel encoder outputs. The choice of material offers distinct advantages: Metal codewheels are highly versatile with a high temperature rating and robust performance; Film codewheels provide higher resolutions; and Glass codewheels combine high temperature resistance with high resolution capabilities. These codewheels are a cost-effective solution for applications requiring precise motion control and feedback.
