HEDS-51X0/61X0 Series, HEDG-512X/612X Series HEDM-512X/61XX Series Two and Three Channel Codewheels for use with Avago Technologies Optical Encoder Modules Data Sheet Description Avago Technologies offers a wide variety of codewheels for use with Avago Technologies’ HEDS-9000, HEDS9100, HEDS-9040, and HEDS-9140 series Encoder Modules. Designed for many environments, applica­tions, and budgets, Avago Technologies’ code­wheels are available in Glass, Film, and Metal. These code­wheels are available in resolu­tions from 96 Counts Per Revolution (CPR) to 1024 CPR on an 11 mm optical radius and 500 to 2048 CPR on a 23.36 mm optical radius. Each of the three codewheel materials offers a certain advantage. Metal codewheels are the most versatile, with a tem­pera­ture rating up to 100°C, resolu­tion to 512 CPR (28 mm diameter), as well as 2 and 3 channel outputs. Film code­wheels offer higher resolution (up to 1024 CPR on a 28 mm diameter) with an operating tem­ perature of 70°C. Glass code­wheels combine the best of film and metal, offer­ing a temperature rating of 100°C and resolutions to 1024 CPR on a 28 mm diameter. In addition, each material offers a specific reliability rating. It is important to consider the specific application operating environ­ment, long term operating conditions, and temperature ranges when choosing a code­ wheel material.

In brief, metal codewheels are rugged, but do not offer higher resolution capabilities. Film codewheels allow higher resolution, but cannot endure the same temperatures and high humidity as metal. Glass codewheels offer both high temperature and higher resolution, but are also more expensive. Consider the following rating table when choosing a codewheel material.
