That is clear object detection. GLV18 Series photoelectric sensors with Clear Object Detection use reflectors to detect transparent objects up to 2.5 m away, or opaque objects up to 5 m away.
Offered in an industry-standard M18 threaded cylindrical housing, the sensor is up to 50% shorter. In addition, the company claims the power consumption is 50% less than many competitive models.
The sensors can detect clear shrink-wrap webs or semi-transparent trays or cartons in material handling applications as well as the presence detection of clear clamshells, bottles, or pouch webstock in packaging applications.
