Incremental linear encoder with Very High Accuracy for large measuring lengths with 5v TTL Quadrature Output
            click here for more images LIP linear encoders from HEIDENHAIN are available in accuracy grades from ± 1 µm to ± 0.1 µm. 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 µm produces an output signal period of 2 µm. This results in a measuring step of only 0.5 µm even without interpolation.
The high uniformity of the scanning signals permits measuring steps as fine as one nanometer.
