Reflective Object Sensor OPB708, OPB709 OPB740 Series, OPB740WZ Series OPB708, OPB709, OPB740, OPB745 Series Features: • • • • • Focused for maximum sensitivity Phototransistor or photodarlington output Crosstalk does not exceed specified ICEO 24” (610 mm) wire length 26 AWG wire size Product Photo Here OPB7_ _WZ Series 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 (RBE) NPN silicon 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: • Non-contact reflective object • Assembly line automation • Machine automation • Machine safety • End of travel sensor • Door sensor • Thermal Paper Mark sensor Part Number OPB708 OPB709 LED Peak Wavelength 935 nm Reflection Distance Inch (mm) Sensor Lead Length/ Wire Type Transistor Darlington OPB740 OPB741 0.150" Minimum Transistor OPB742 OPB743 OPB744 OPB745 OPB740WZ 890 nm Darlington OPB741WZ CONTAINS POLYSULFONE To avoid stress cracking, we suggest using ND Industries’ Vibra-Tite for thread-locking. Vibra-Tite evaporates fast without causing structural failure in OPTEK’s molded plastics. Applies to: OPB460, OPB470, OPB480, OPB490.
