The polarized reflective sensors are available in models for both solid and transparent material and the diffuse reflective is also available in a focalized version. The small, 12mm-by-33mm package makes these IP66-rated sensors well-suited for tight mounting locations on semiconductor machinery, packaging machinery and assembly systems. Sensing distance range is from 0.2cm up to 6m, depending on the model.Automation Systems Interconnect Inc.www.asi-ez.com877.650.5160
