Photoelectric sensors with Clear Object Detection detect transparent, opaque objects

The GLV18 series of photoelectric sensors with Clear Object Detection, made by Pepperl+Fuchs, detect objects to a contrast as low as 18 percent.


GLV18 Series photoelectric sensors with Clear Object Detection are now available from Pepperl+Fuchs. Clear object detection models 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%, including objects as transparent as glass or a clear film. They carry the CE mark, and are UL/cUL Listed.Pepperl-Fuchs Clear-Object

“The primary benefit of clear object detection is the ability to consistently detect transparent materials such as a glass bottle, PET plastic, a web of shrink-wrap, or protective bubble wrap,” says Jeff Allison, Product Manager. “Other types of photoelectric sensors would not consistently detect clear objects because the transmitted light would optically burn through the material, but GLV18 series clear object detection sensors are designed to detect such materials.”

These sensors come in an industry-standard M18 threaded cylindrical housing that is purportedly up to 50% shorter and with up to 50% lower power consumption than many competitive models. As a result, they are allegedly 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 to facilitate precise positioning of GLV18 series sensors.

Status LEDs are highly visible and placed in dual positions, 180 degrees apart on the housing, for increased visibility. Additionally, status LED functionality is purportedly 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 suited for use in material handling applications, primarily for detecting clear shrink-wrap webs or semi-transparent trays or cartons. They are also well suited for use in packaging applications including, among others, presence detection of clear clamshells, bottles, or pouch webstock. Additionally, the GLV18 series is a very reliable general purpose sensor family that can be used in a number of other markets, including mylar detection in printing/paper applications, and glass detection in automotive applications.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
