Photoelectric Sensors with Clear Object Detection

Pepperl+Fuchs' GLV18 Series photoelectric sensors with Clear Object Detection are clear object detection models and use reflectors to detect transparent objects up to 2.5 m away, or opaque objects up to 5 m away. These sensors can detect transparent objects to a contrast as low as 18 percent, including objects as transparent as glass or a clear film. They carry the CE mark, and are UL/cUL Listed.

These sensors come in an industry-standard M18 threaded cylindrical housing and Pepperl+Fuchs says that is up to 50 percent shorter and with up to 50 percent lower power consumption than many competitive models. As a result, they are more likely to fit into space-critical equipment or installations and are less costly to operate - and as lower power consumption enables each power supply to power more sensors, fewer power supplies may be needed in a given application.

GLV18 series sensors also include a unique flush-mount bracket that allows for a simple, tool-less, unobtrusive means of mounting the sensor on a conveyor. Ball-and-swivel and half-clamp mounting brackets are also available. 

Status LEDs are highly visible and placed in dual positions, 180 degrees apart on the housing, for increased visibility. Additionally, status LED functionality is standardized, meaning that GLV18 sensors don't just indicate they are powered and see a target, but also indicate if the sensor's signal strength is lower than it should be so that corrective action can be taken. 

GLVL18 series sensors are useful in material handling applications, primarily for detecting clear shrink-wrap webs or semi-transparent trays or cartons, but are also well suited for use in packaging applications including presence detection of clear clamshells, bottles or pouch webstock. The sensor can be used in other markets such as mylar detection in printing/paper applications and glass detection in automotive applications.
