ETC OPB743W

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 mounted side
by side on converging optical axes in a black
plastic housing.

NOTES
1
RMA Flux is recommended. Duration can be extended to 10sec. max. when flow soldering.
2
Derate Linearly 1.82mW/oC above 26oC
3
d is distance from the assembly face to the reflective surface.
4
Reflective surface is Eastam Kodak neutral white test card with 90% diffuse reflectance as a .... reflective surface.
5
Lower curve is based on calculated worst case condition rather than the conventional -20 limit.
6
Crosstalk is the photocurrent measured with current to the input diode & no reflecting surface.
7
All parameters tested using pulse technique.
