SICK’s WL27-3 Reflex Array photoelectric sensor provides reliable leading and continuous edge detection of irregularly shaped objects, pallets and multi-height objects at a low cost.
Any object 12 mm or larger is detected with the Reflex Array’s 50 mm detection height. Operating in a “reflex” (retro-reflective) mode results in only having to mount and power a single device, reducing costs. An intuitive alignment/teach procedure quickly ensures the device is operating under ideal conditions with the reflector. A high-resolution version offers a Minimum Detectable Object (MDO) resolution down to 5 mm with 24 mm detection height.
