Description: Each reflectve object sensor in the OPB708, OPB709, OPB740 through OPB746 and OPB740WZ through OPB746WZ series consists of an infrared emitng diode and a NPN silicon phototransistor or a photodarlington. The OPB747WZ and OPB748WZ consist of a Red visible LED and a low light level rejecton (RBE) NPN silicon phototransistor. The Red LED allows beter contrast rato when detectng Black marks on a White surface. All these devices are mounted side-by-side on converging optcal axes in a black plastc housing focusing on a small area and depth of feld. Features: • Focused for maximum sensitvity • Phototransistor or photodarlington output • Crosstalk does not exceed specifed ICEO • 24” (610 mm) wire length • 26 AWG wire size Applications: • Non-contact reflectve object sensor • Assembly line automaton • Machine automaton • Machine safety • End of travel sensor • Door sensor • Thermal Paper Mark
