OPB739RWZ

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. This sensor can be used with Opteks OCB100CZ auto calibration module to reduce variability from sensor to sensor and to achieve a digital output. Custom electrical, wire, cabling and connectors are available. Contact your local representative or OPTEK for more information .
