Sick has launched the WL27-3, a reflex array photoelectric sensor
developed for reliable detection of pallets and irregularly shaped and multiheight
objects. Any object 12 mm or larger is detected with the sensor’s 50-mm-detection
height, regardless of its properties or position within the array, including clear
materials. Sensing range is 4.5 m. Designed for simple light grid applications,
the reflex array provides low-cost area detection in a standard sensor platform.
Operating in reflex (retroreflective) mode results in having to mount and power
only a single device, reducing costs. Applications include leading-edge detection
of products with tapered edges (totes), bagged products, warped boards and packaged
products, as well as continuous-edge detection of containers with holes/gaps.
