LINEAR GAUGE Full Lineup of Gauge Heads from Ultra-high Precision to Excellent Cost-performance Types Mitutoyo Precision Gauge Heads

Measurement principle Optical transmission-type linear encoders The gauge heads mainly use optical transmission-type linear encoders, the principle of which is shown below. In this type, the light source (LED) and the detector element (photodiode) face each other with the main scale and index scale (20 µm pitch) positioned between them. As the scale moves with respect to the detector, the intensity of the light passing through the window in the index scale varies constantly. At this time, two synchronized sine-wave signals having a relative 90-degree phase difference are output. These...
