Electrical Characteristics
Electrical Characteristics over Recommended Operating Range, typical at 25 C.
Encoding Characteristics
Encoding Characteristics over Recommended Operating Range and Recommended Mounting Tolerances.
These Characteristics do not include codewheel/codestrip contribution. The Typical Values are averages over
the full rotation of the codewheel. For operation above 100 kHz, see frequency derating curves.
Note: Module mounted on tolerance circle of
3.3 k
