Sick MLG-2 automation light grids

Reliable and robust sensors for detecting presence, checking for projections, and measuring the height of load carriers and their loads are necessary for ensuring stable and error-free material flows in materials handling and storage processes in high-bay or vertical stores. Automation light grids measure the height of the load so that, for example, a height-dependent storage space can be reliably determined.

The MLG-2 light grids are claimed to offer optimised speed, resolution and optics so that even transparent, small and rapid objects can be detected.

The basis of the light grid platform for automation technology is a specially developed ASIC that enables numerous functions which, when combined with the consistent modularity of the MLG-2 regarding the beam grid, monitored height, range and interfaces, means that the light grid can be configured for every application - precisely covering the desired demands and automation requirements.

The sensor family meets the needs of standard and demanding applications with the ‘Prime’ and ‘Pro’ variants. The measuring light grids permit monitoring heights of up to 3.2 m - with modular configuration within a 150 mm grid. Objects with a minimum size of 2 mm can be detected due to the cross-beam function of versions with beam distances of 5, 10, and 25 to 50 mm.

Both versions can transmit analog measurement values, permit flexible beam evaluation, are easily parameterised, offer common interfaces, are ready for IO-Link integration, and offer energy-saving green mode.
