OPB 740
Series Reflective Object
Sensors
Description
The OPB740 through OPB744 series of
reflective object sensors each consist of an
infrared emitting diode and an NPN silicon
phototransistor mounted side by side on
converging optical axes in an black plastic
housing. Various options include choice of
no windows, blue polysulfone windows for
dust protection or opaque windows with
offset openings for improved resolution.
Available with wires as OPB740W /
OPB744W series.
The OPB 745 reflective object sensor
consists of an infrared emitting diode and an
NPN silicon photodarlington .
