Reflective Object Sensor OPB708, OPB709, OPB740 Series, OPB740WZ Series

The OPB708, OPB709, OPB740 through OPB746, and OPB740WZ through OPB746WZ series are reflective object sensors. These devices consist of an infrared emitting diode and either an NPN silicon phototransistor or a 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. All models are housed in a black plastic enclosure with side-by-side components on converging optical axes, designed for focused detection within a small 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. These sensors detect reflective objects within their field of view. Custom options for IC(ON) current binning, wire lengths, and connectorization are available.

Applications

Non-contact reflective object sensor
Assembly line automation
