Versatile Reflective Optical Sensor For Industrial & Medical Apps


TT Electronics has unveiled a versatile reflective optical sensor with robust built-in ambient light immunity. It can be used in a wide variety of industrial and medical applications, including: industrial printing, dispensing, manufacturing automation, safety and security devices, portable lab/medical equipment.

The new OPB9000 features unparalleled 25+ kilolux ambient light immunity for dependable edge and presence detection of reflective media in a wide range of ambient light conditions – from dark rooms to bright sunlight.

The new sensor is a reflective, CMOS logic output sensor with programmable sensitivity, output polarity, and drain select. The self-calibration feature avoids the need for constant recalibration as the LED ages, saving valuable time and effort.

Robust, industrial grade resin allows the sensor to operate at a wide temperature range from -40C to + 85C, ideal for the harshest environments.


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.

Response time is 6µs to ensure high-speed detection for time-critical applications.

The chip eliminates the need for peripheral circuitry like op-amps, data converters, and comparators, as all analog signal conditioning is integrated in the IC. This allows it to reduce board space requirements by up to 80%. 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.
