Description:

The OPB739RWZ is a reflective line reader sensor. The sensor utilizes a visible red (650 nm) 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” [0.1 mm] at the optimum distance of 0.030” [0.76 mm] 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.

Custom electrical, wire, cabling and connectors are available. Contact your local representative or OPTEK for more information.
