Dadisick's Background Suppression Photoelectric Sensor GB43 Series is not affected by the target color and background color and can accurately detect objects. It has high accuracy, small differential distance, and can detect tiny step differences. It is anti-interference and can also resist variable frequency fluorescent lamps based on the unique external interference light avoidance algorithm. The perfect application of the BGS function does not require adjustment of the detection distance even when changing production on a production line with heterochromatic workpieces.
