THEORY OF OPERATION OPB732 / OPB732WZ
(mounting tabs and wires) are non-focused analog output reflective
sensors designed to operate from .05” [1.27mm] to 2”[50.8mm] or
greater with an output signal significantly above the typical back-
ground signal in a dark environment. These sensors are tested against
a white 90% reflectance white card at a distance of 1.0” to guaran-
tee a minimum Ic
IF = 30mA. Other surfaces will give different signal levels.
from an LED with a total half power angle (ØHP, Beam Angle) around
18°. When the light strikes an object, it is reflected back toward
the phototransistor. The amount of current Ic
phototransistor is dependent upon the amount of light striking it. The
following graph shows the effect of target distance on the output
current of the OPB732.
