Description:
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.
