The MLG-2 WebChecker automation light grid automatically finds up to 10 edges and measures these in relation to a reference edge. Up to 5 different web widths can be measured at the same time. With semi-transparent materials, defined inner edges can also be detected and measured. Thanks to its modular design, the MLG-2 WebChecker is well-suited for various monitored areas, interfaces and sensing ranges. Measuring fields of a minimum of 150 mm x 200 mm up to maximum of 2,500 mm x 3,150 mm can be implemented. The MLG-2 WebChecker communicates with different controllers. The end customer can therefore very easily change the format on the machine via fieldbuses or IO-Link.
