OPB710 and OPB710F consist of a gallium arsenide infrared emitting diode and an NPN silicon phototransistor. OPB730 and OPB730F consist of a gallium arsenide infrared emitting diode and an NPN silicon photodarlington. On each sensor, the emitting diode and detector are mounted side-by-side on parallel axes in a standard TO-72 header. A black plastic sleeve is attached and filled with encapsulating epoxy to cover the emitter and detector. The OPB710F and OPB730F (“F” versions) have a filtering material added to the epoxy to reduce the effect of ambient light. The package contains an internal barrier which prevents diode emissions from reaching the sensor directly. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.
