Focused for maximum sensitivity Phototransistor Output 650nm Visible Red LED to optimize detection of dye based inks Low-cost plastic housing 24” minimum 26AWG wire leads Optimal operating distance range 0.015” [.38mm] to 0.045” [1.14mm]
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.
