SICK Sensor Intelligence has launched the WL27-3 Refl ex Array photoelectric sensor for leading edge detection of irregularly-shaped objects. Any object 12mm or larger can be detected with the Refl ex Array’s 50mm detection height, regardless of object properties or position within the array, including clear materials.

The WL27-3 Refl ex Array provides low-cost area detection in a standard sensor platform. Operating in a ‘refl ex’ (retro-refl ective) mode, only a single device must be installed. An intuitive alignment and teach procedure ensures the device is operating under ideal conditions with the refl ector. A high resolution version offers a Minimum Detectable Object (MDO) resolution down to 5mm, with 24 mm detection height.
