Description:
OPB700 and OPB700ALZ sensors consist of an infrared emitting diode and a 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 a NPN silicon photodarlington,
mounted side-by-side on converging optical axes in a black plastic housing.
The interconnect wires for these devices are are UL approved #26 AWG, with Teflon insulation, stripped and
tinned. The OPB700 and OPB701 have 4” (101 mm) wire length while the OPB700ALZ and OPB70 1ALZ have
18” (457 mm) wire length.
Custom electrical, wire, cabling and connectors are available. Contact your local representative or OPTEK for
more information.
