The OPB739RWZ is a reflective line reader sensor. The sensor utilizes a visible red (650nm) LED and an NPN silicon

phototransistor mounted side by side on converging optical axes in a black plastic housing. The converging light beam

makes this sensor capable of detecting line widths as small as 0.004” [0.1mm] at the optimum distance of 0.030” [0.76mm]

from the target. The red LED maximizes the reflected signal contrast of black lines on white backgrounds. Recommended

line spacing is .050” minimum.

This sensor can be used with Optek’s OCB100CZ auto calibration module to reduce variability from sensor to sensor and to

achieve a digital output.
