Reflective Object Sensor

OPB710, OPB710F, OPB730, OPB730F

F-Package

Features:

(OPB710F, OPB730F)

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.
