Reflex array sensor - Sick Inc

The WL27-3 reflex array photoelectric sensor provides leading and continuous-edge detection of irregularly shaped objects, pallets, and multiheight objects.

The sensor detects objects 12 mm or larger with its 50-mm detection height, regardless of the object’s properties or position within the array — including clear materials.
The unit’s “reflex” (retroreflective) mode results in only having to mount and power a single device. An intuitive alignment/teach procedure quickly ensures the device is operating correctly. A high-resolution version offers a minimum detectable object resolution down to 5 mm with 24‑mm detection height.
