The OPB708, OPB709, OPB740 through OPB746, and OPB740WZ through OPB746WZ series reflective object sensors each comprise an infrared emitting diode and an NPN silicon phototransistor or photodarlington. The OPB747WZ and OPB748WZ feature a Red visible LED paired with a low light level rejection (RBE) NPN silicon phototransistor, offering enhanced contrast for detecting black marks on white surfaces. These devices are housed in black plastic with converging optical axes, focusing on a specific area and depth of field. The OPB_WZ series includes UL-approved wiring and various lens options, such as no windows, blue polysulfone for dust protection, or opaque aperture windows with offset openings for improved target resolution. The integrated photosensor activates only when a reflective object enters its field of view. Custom IC(ON) current binning, specialized wire lengths, and connectorization are available upon request. These sensors are ideal for non-contact object detection in assembly line automation, machine automation, machine safety, end-of-travel sensing, door sensing, and thermal paper mark detection.
