Description:
Each reflective object sensor in the OPB708, OPB709, OPB740 through OPB746 and OPB740WZ through
OPB746WZ series consists of an infrared emitting diode and a NPN silicon phototransistor or a photodarlington.
The OPB747WZ and OPB748WZ consist of a Red visible LED and a low light level rejection (R
phototransistor. The Red LED allows better contrast ratio when detecting Black marks on a White surface. All
these devices are mounted side-by-side on converging optical axes in a black plastic housing focusing on a small
area and depth of field.
OPB7 _ _ WZ series are wired (UL approved wire) devices that offer various lens options, including no windows,
blue polysulfone windows for dust protection or opaque aperture windows with offset openings for improved target
resolution.
On each sensor included in this data sheet, the photosensor responds to radiation only when a reflective object
passes within its field of view.
Custom IC(ON) current binning, special wire lengths and connectorization is available through your OPTEK rep.
Applications:
Vibra-Tite evaporates fast without causing structural
