Pepperl+Fuchs introduces LGS Series light grids. 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. As a result the LGS series is an easy-to-install, commission and operate sensing solution ideally suited for warehousing, material handling, packaging and general automation applications. 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.

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 4mm. Examples of more advanced applications include overhang detection or web sag and height monitoring. Using the integrated height monitoring function, up to 3 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.

The range of operating modes and features can help improve productivity by enabling new detection solutions. Three separate height switching outputs control object height or tension checks and enable the LGS to detect or report three height profiles. Using flexible teach-in options these light grids can identify objects via their geometry, including objects with gaps and openings, when they are moving or in a fixed position.

Commissioning and operation are similar to standard photoelectric sensors – users simply position the transmitter and receiver opposite each other and signal calibration occurs automatically. Desired features are set without any software, and an innovative touch field with illuminated pictograms facilitates quick and easy step-by-step programming without a PC. Standby mode minimizes energy consumption and maximizes service life in applications where the light grids are not in continuous operation.

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.
