Most optical encoders are supplied in several diameters, based on limitations in code wheel and interpolation technology (the higher the resolution, the larger the code wheel diameter). The Avago AEDA-3300 series encoders are the same diameter regardless of resolution, with a total package size of 17 mm diameter by 24 mm high for the version designed for manufacturers of housed encoders. This means that the encoder engine will fit within an 18 mm diameter optical encoder package. For motor manufacturers incorporating an optical encoder as part of a complete motor assembly, Avago also offers a version with a mounting plate (28 mm diameter by 27 mm high).
No special alignment tool is required, since the AEDA-3300 encoder is supplied in a package in which the code wheel has been pre-aligned to the encoder optics. The integrated bearing stage also allows for a greater tolerance to customer shaft position variations, without affecting the encoder performance.
