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 ]

Detection example 1

Flat workpiece

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

Detection example 2

Rough workpiece
