Old LS series:
LS 50x; LS 80x
(e.g. LS 503; LS 803)
I 0 = 5 ... 15µAss

Example:
Reference mark signal
Caution: The reference-mark edges (ref. Mark / Uo line) must not intersect outside
the tolerance range!
Note:
The quality of the output signals has an influence on the measuring accuracy of the linear and rotary
encoders.
The tolerances stated are valid for standard applications of HEIDENHAIN encoders (e.g. LS on machine tools
with measuring steps up to 1 µm).
For operation with encoders with higher accuracy (e.g. exposed, contactless encoders, angle encoders and
encoders with highly interpolated output signals) the tolerances for the output signals are smaller.
HEIDENHAIN compares precision encoders to a measuring standard after adjustment.
