LGS Series Light Grids a 2012 Design News “Golden Mousetrap” Finalist

Design News Golden Mousetrap 2012

Pepperl+Fuchs' LGS Series light grids have been named a 2012 Design News magazine Golden Mousetrap finalist in the Automation and Control: Sensors, Vision Systems, Feedback Devices category. Advanced functions such as object identification and height monitoring capability – features typically found only on significantly more expensive sensing devices – enable users to significantly simplify many typical automation tasks. For more than two decades, the Design News Awards Program has recognized engineering innovation and creativity in product design. 

“We are honored that our LGS Series light grids have been named a Golden Mousetrap finalist,” says Michael Turner, Product Manager, Pepperl+Fuchs. “These light grids come with a range of noteworthy functions previously found only on much more expensive devices, including lightning speed object detection even with beam crossover enabled, the option of not just detecting objects but identifying them too, and even remotely communicating data via an IO-Link interface.”

Additionally, with LGS light grids even if one or two beams are permanently obstructed due to circumstances in the application, they can be ignored with the beam blanking function. At startup, the signal strength is automatically adjusted and optimized for the environmental conditions, making switching more reliable and enabling faster response times.

The LGS Series features a slim IP67 enclosure housing with the control unit integrated into the receiver module, uncomplicated plug-and-play mounting, plus software-free and PC-free programming.

The feature-rich and cost-effective design of the LGS Series makes it an ideal solution for applications ranging from the simple to the complex. Examples of relatively simple applications include monitoring an area for falling objects, ejection control, and the detection of parts as small as 4 mm. Examples of more advanced applications include overhang detection, web sag, and height monitoring. Using the integrated height monitoring function, up to three levels of control can be set with the touch field. More complex application examples include object or hole profiling, where objects can not only be detected but identified using the integrated object identification function. In any of these applications, programming and detection is accomplished quickly and easily without requiring a PC and without using software.

LGS light grids are available in customizable lengths from 100 mm to 3,200 mm, a broad range of resolutions from 8 mm up to 100 mm, and provide reliable operation in temperatures as low as -30 degrees °C. Response time varies from 2 ms to 20 ms depending on the number of beams (4 beams to 253 beams) in the light grid.
