Encoding Characteristics

Encoding Characteristics over the Recommended

Operating Conditions and Mounting Conditions. These

characteristics do not include codewheel/codestrip

contribution.

1. The typical values are average over the full rotation

of the codewheel at Nominal Mouting Position and

Typical Operating Conditions.

2. For a codestrip, the Typical Values are obtained at

zero angular displacement and Typical Operating

Conditions.

3. Maximums are the worst case values predicted

over the full range of Recommended Mounting

Tolerances and Operating Conditions, with

consideration to population shift.
