EXPOSED LINEAR SCALES ENCODERS


LIP
LIP linear encoders from HEIDENHAIN are available in accuracy grades from 1 m to 0.1 m. Through the choice of scale material it is possible to use a measuring standard whose thermal behavior is comparable to that of the measured objects.

A grating period of 4 m produces an output signal period of 2 m. This results in a measuring step of only 0.5 m even without interpolation.

The high uniformity of the scanning signals permits measuring steps as fine as one nanometer.
