A device connector includes device-side terminals, a device-side shield shell, harness-side terminals to be fixed to a plurality of wires and connected to the device-side terminals by bolts and a harness-side shield shell connected to a braided wire surrounding the wires. The method encompasses directing a beam of light or radiation at a feature and detecting a reflected beam associated therewith. The methods and apparatus are applicable, for example, in a variety of plant products including the treating of corn, soybeans, peas, wheat, wheat flour, and durum pasta and in a variety of industrial processes including wet and dry milling and refining operations.
