OPB606A is an optical reflective analog output sensor, consisting of an infrared emitter and an NPN open-collector phototransistor. It is widely used in various applications due to its versatile design and performance.

The OPB606A is designed for use in many types of applications from low speed to moderate speed sensing, reflective optical feedback systems, and optical barriers. It is constructed with a reflecting surface integral with the phototransistor, making it ideal for use in systems requiring a gap between the emitter and phototransistor. This gap is necessary for accurate optical feedback and the OPB606A\'s design makes it easy to adjust the gap size and optimize its performance.

The OPB606A is an ideal choice for industrial applications, such as automated process control, container level sensing, barcode readers, robotic systems, and others. It is also used in scientific applications for precise measurement and control, such as robotics applications and research.

The working principle of OPB606A is based on infrared light reflection. It consists of an infrared LED emitter and a NPN open-collector phototransistor which is built into the package. The emitter is positioned on one end of the package and the phototransistor is positioned at the opposite end, separated by a narrow gap. When the emitter is turned on, the light beam will be emitted and reflected by an object placed in front of the package. The optical reflection will then be detected by the phototransistor, generating an electrical signal. The output voltage of the device depends on the distance between the emitter and the object. The closer the object is to the package, the higher the output voltage. This type of sensing is highly sensitive and reliable, making it suitable for applications such as line tracking, object detection, color recognition, distance measurement, and many other applications.

Moreover, the OPB606A has a wide operating voltage range from 4 to 28 volts, allowing for a wide variety of applications and circuitry configurations. It also has a low supply current, low dark current, and very low noise. It is constructed with an environmental resistant polycarbonate package, which makes it suitable for use in both internal and external applications.

Overall, the OPB606A is an excellent optoelectronic sensor for use in various industrial and scientific applications. It is highly reliable, accurate, and robust, making it perfect for use in a wide range of applications that require precise distance measurements and readings.
