SICK Photoelectric Retro-Reflective Sensor PLG3 Series

The SICK automation light grids can be used in a number of solutions, such as detecting and counting irregularly shaped objects, people and vehicles, and checking for presence and pallet overhang detection. The tasks are so versatile that one light grid cannot fulfil the requirements of every application. Light grids from SICK offer multiple ranges, heights, sizes, orientations, and resolutions which simplify integration through high flexibility and performance. Using sensors for order picking has become standard in the automotive and logistics industries. Using the PLG automation light grid for order picking offers significant advantages over conventional, manual order picking technology.

The PLG is mounted at each storage bay and has an integrated job LED to display pick position. The PLG’s single-sided reflector strip saves space in the bin and reduces damage and installation costs.
