The term angle encoder is typically used
to describe encoders that have an accuracy
of better than ± 5" and a line count
above 10 000.
In contrast, rotary encoders are encoders
that typically have an accuracy better
than ± 10“.
Angle encoders are found in applications
requiring precision angular measurement
to accuracies within several arc seconds.
