Reflective Object Sensor OPB708, OPB709 OPB708, OPB740 Series, OPB740WZ Series OPB709, OPB740, OPB745 Features: Series Focused for maximum sensitivity Phototransistor or photodarlington output Crosstalk does not exceed specified ICEO 24 (610 mm) wire length OPB7 WZ 26 AWG wire size Series Description: Each reflective object sensor in the OPB708, OPB709, OPB740 through OPB746 and OPB740WZ through OPB746WZ series consists of an infrared emingtti 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 ) NPN silicon phototransistor. The Red LED allows BE 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.
