The OPB708, OPB709, OPB740 through OPB746, and OPB740WZ through OPB746WZ series are reflective object sensors. Each unit comprises an infrared emitting diode and either an NPN silicon phototransistor or a photodarlington. The OPB747WZ and OPB748WZ models 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 sensors are designed with side-by-side mounting on converging optical axes within a black plastic housing, focusing on a specific area and depth of field. The OPB_WZ series includes UL-approved wire and offers various lens options, such as no windows, blue polysulfone windows for dust protection, or opaque aperture windows with offset openings for improved target resolution. The photosensor in each device activates when a reflective object enters its field of view. Custom options for IC(ON) current binning, wire lengths, and connectorization are available.
Applications include non-contact reflective object sensing, assembly line automation, machine automation, machine safety, end-of-travel sensing, door sensing, and thermal paper mark detection.
