Incremental linear encoders for limited installation space, high traversing speeds, and medium traverses up to 6m with 5v TTL Quadrature Output
LIDA 477 incremental linear encoders use AURODUR steel scales with grating periods of 20 µm as measuring standard. The new LIDA models are relatively insensitive to scale contamination and unevenness of the mounting surface.Measuring standard - AURODUR steel scale tape with AURODUR graduation 20 µm
Output signals - 5v TTL Quadrature
Signal period - 4 um, 2 um, 0.4 um, 0.2 um
Accuracy grades - ± 15 µm
Recommended measuring steps - 0.05 um
Measuring lengths - 240 mm to 6040 mm
Maximum traversing speed - 480 m/min at -3dB cutoff frequency >200 kHz
Reference mark - One position at midpoint of measuring length
