The OPB739RWZ is a reflective line reader sensor combining a 650nm visible red LED and an NPN silicon phototransistor in a black plastic housing for detecting fine lines and marks. It operates optimally at 0.030 inches (0.76mm) from the target, detecting line widths as small as 0.004 inches (0.1mm), with a recommended minimum line spacing of 0.050 inches. The device has a storage and operating temperature range of -40°C to +85°C, an LED forward current of 40mA, and a phototransistor collector-emitter breakdown voltage of 30V. It meets RoHS standards.
