Sick, a manufacturer of sensors, safety systems, and machine vision and automatic identification products for factory and logistics automation, has introduced the WL27-3 Reflex Array photoelectric sensor for the leading-edge detection of irregular shaped objects. Any object 12 mm or larger is detected with the Reflex Array's 50 mm detection height, regardless of object properties or position within the array.
The WL27-3 Reflex Array provides low-cost area detection in a standard sensor platform. The unit's "reflex" (retro-reflective) mode of operation means only a single device must be mounted and powered, reducing costs. Further, 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.
Applications include leading-edge detection of irregularly shaped objects, such as products with tapered edges (totes), bagged products, warped boards, and packaged products. This also includes continuous-edge detection of multi-height objects, pallets, and containers with holes or gaps. With these applications, the reflex array can oftentimes displace the traditional approach of using small light grids or stacked photoelectric sensors.
