Pepperl+Fuchs Inc.’s RLG28 retroreflective area sensors feature six light beams that generate a constant 60-mm detection field to consistently detect objects as small as 12 mm in diameter over the entire sensing range (0 to 4 m). They are suitable for use in materials handling and other applications where single-beam retroreflective sensors have reached their functional limitations, or in applications that would otherwise require costly light grids. The sensors are cULus-listed. They can detect leading edges of objects, regardless of shape, position or texture, and with no readjustment or realignment needed. They are suitable for detecting the leading edges of pallets on palletizers and for identifying protruding pallets.
