          Digital CMOS Laser Sensor

          GV series

          World's First Datum Algorithm

          When the datum(background,reference surface) tuning is performed, workpieces can be correctly detected.

          Datum algorithm

          Based on:
          ・Distance
          ・Received light pattern

          Datum tuning

          Easy tuning Just by pressing the [SET] button with a target on a conveyor.

          target

          When performing the datum tuning (reference surface calibration)with a target on a conveyor (background), the values are set slightly above and slightly below the conveyor position. With no workpiece in place, the light waveform falls within this range -> [ Output OFF ]

          target1

          The CMOS light receiving position changes -> The distance changes -> The workpiece is judged as present -> [ Output ON ]
