Function: LGM50

Automation light grids in the LGM Series are designed to measure small to large objects. The slimline light grids are modular in design and are available with various beam gaps and field heights. The entire signal evaluation process is carried out within the device. The lightweight systems can be integrated elegantly into their surroundings, from both a technical and a visual perspective. As a result, machines and plants operating in temperature ranges between -30 °C ... +60 °C can be designed to more compact dimensions.
