TT Electronics — SMD Reflective Optical Sensor: OPB9000


TT Electronics Logo
The OPB9000 is a versatile sensor that can be used in a wide variety of industrial and medical applications. The sensor features market leading ambient light immunity which allows operation from dark rooms to bright sunlight. It can detect various types of media with as little as a 30% change in reflectivity. Robust, industrial grade resin allows the sensor to operate at a wide temperature range from -40°C to +85°C, ideal for the harshest environments.

Factory calibrated to a white card at a 12mm distance to offer plug and play detection, the OPB9000 can be recalibrated in a matter of milliseconds with a single command for specific application requirements. Integrated automatic temperature compensation maximizes detection consistency and reliability. The small footprint saves valuable PCB real estate as devices become smaller and more portable.

The OPB9000 eliminates the need for peripheral circuitry like op-amps, data converters, and comparators, as all analog signal conditioning is integrated in the IC.
