OPB9000 is a versatile sensor designed for 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 -40C to + 85C, for the harshest environments.

Overview

The OPB9000 is a reflective, CMOS logic output sensor with programmable sensitivity, output polarity, and drain select. Unparalleled 25+ kilolux ambient light immunity along with a wide operating temperature range sets the OPB9000 apart. Factory calibrated to offer plug and play detection, OPB9000 can be re-calibrated in a matter of milliseconds with a single command for specific application requirements. This self-calibration feature eliminates the need to constantly recalibrate as the LED ages, saving valuable time and effort.

Temperature compensation and automatic gain control features enable it to reliably function in the most demanding and dynamic environmental conditions where consistent performance from sensor devices is critical. The 6µs industry leading response time ensures high-speed detection for time-critical applications.
The OPB9000 eliminates circuit complexity and reduces board space requirements by up to 80% with its fully integrated analogue front end and digital interface. It combines an infrared emitter and integrated logic sensor in a miniature 4.0 mm x 2.2 mm x 1.5 mm surface-mount package.

The OPB9000 removes the need for peripheral circuitry like op-amps, data converters, and comparators, as all analog signal conditioning is integrated in the IC. The sensor is suitable for a variety of applications including industrial printing, dispensing, manufacturing automation, safety and security devices, and portable lab/medical equipment.
