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 Features: 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. • Codewheels Available in Glass, Film, and Metal 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.

See Encoder Module Data Sheet for specifications and output load recommendations. *HEDM-6140 is guaranteed to 100 kHz with the HEDS-9040 #T00 module.  Encoding Characteristics Reliability Encoding characteristics over recommended operating range and recommended mounting tolerances unless otherwise specified. Values are for worst error over a full rotation. Please refer to Encoder Module Data Sheet for definitions of Encoding characteristics. In addition to the absolute maximum specifications of codewheels, the environment characteristics of the applica­tion are also important. For example, consistent, large tem­perature swings over the life of the product will affect the code­wheel performance charac­ter­istics depending on the material. The following reliabil­ity table shows results of lifetests under varying condi­tions of temperature and humidity. Part Number Description Typ. Max.

Figure 1a shows mounting the module with side A as the mounting plane. Figure 1b shows mounting the module with side B as the mount­ing plane. When assembling the encoder and codewheel, it is important to maintain the tolerances of Side A of the module, and the image side of the codewheel. See module Data Sheets for these tolerances. Mounting a high resolution or three channel encoder with Module Side A as the mounting plane requires alignment pins in the motor base. These alignment pins provide the necessary centering of the module with respect to the center of the motor shaft. In addition to centering, the codewheel gap is also important. Please refer to the respective encoder data sheet for necessary mounting information. Mounting with Module Side B as the Mounting Plane, using Avago Technologies Assembly Tools Avago Technologies offers centering tools and gap setting tools only for the case when the module is mounted with Side B down. Please refer to the Ordering Information Table to choose the correct assembly tools. MODULE SIDE B IMAGE SIDE OF CODEWHEEL IMAGE SIDE OF CODEWHEEL MODULE SIDE B MODULE SIDE A Figure 1a. Figure 1b. *Please note that the image side of the codewheel must always be facing the module Side A.

Do not tighten screws. 1. Place codewheel on shaft. 2. Set codewheel height: a. Place the correct gap setting tool (per Ordering Information Table) on motor base, flush up against the motor shaft as shown in Figure 2. The shim has two different size steps. Choose the one that most closely matches the width of the codewheel boss. The shim should not contact the codewheel boss. b. Push codewheel down against gap setting shim. The codewheel is now at the proper height. 4. Slide the HEDS-8905 or HEDS-8906 centering tool over codewheel hub and onto module as shown in Figure 3. The pins of the alignment tool should fit snugly inside the alignment recesses of the module. 5. While holding alignment tool in place, tighten screws down to secure module. 6. Remove alignment tools. c. Tighten codewheel setscrew.
