The GV Series digital CMOS laser sensor uses a Datum algorithm to detect targets that conventional sensors cannot.
The optical-triangulation sensor detects shiny targets with multiple reflections, light-absorbing materials, such as black rubber; and target presence or absence based on surface qualities or target height and provides a GO/NG output. The Series has four IP67-rated sensor-head models with detection ranges of 45, 130, 450, and 1,000 mm.
The Datum algorithm uses an innovative calibration technique where the received light waveform pattern from a target or background is used to set upper and lower received light limits.
Three detection modes are selectable: Edge hold detects sudden changes in workpiece height; surface detection detects the nearest surface, and a clamp function that ignores targets too close to the sensor head. A sensor’s panel has a dynamic multisegment-bar LED display. The number of individual LED bars that display red or green confirm the instantaneous detection status.
