SICK, Inc: Light grid sensors

The versatile MLG and ELG can be used for handling items on conveyors, for order fulfillment, or in other packaging applications. The light grids come in standard and programmable models. Standard models perform like a typical through-beam sensor and provide an output if any of the beams are interrupted. Programmable models are more flexible in application due to their ability to detect, interpret, and give outputs based on which beams are interrupted.
