OPB702 Optek, Through Hole Reflective Optical Sensor, Phototransistor Output

OPB700/701/702 Reflective Object Sensors. OPB700 and OPB700ALZ series of sensors from Optek consist of an infrared emitting diode and an NPN silicon phototransistor, mounted side-by-side on converging optical axes in a black plastic housing. OPB701 and OPB701ALZ sensors consist of an infrared emitting diode and an NPN silicon photodarlington, and also mounted side-by-side on converging optical axes in a cost-effective black plastic housing. The interconnect wires for these devices are UL approved #26 AWG, with Teflon insulation, stripped ; tinned. The OPB700 and OPB701 have 4" (101 mm) wire length while the OPB700ALZ ; OPB701ALZ have 18" (457 mm) wire length.
