The OPB702 is a type of optical sensor that uses reflection to measure the presence or absence of an object. It works by reflecting light off of an object and then measuring the intensity of the reflected light. The sensor can be used to detect objects of different shapes and sizes, or to monitor the presence and movement of an object. It is most commonly used in industrial applications, such as automated manufacturing and assembly lines.

The working principle of the OPB702 can be divided into two parts: the optical sensing and the analog output. The optical sensing utilizes the photo-electrical effect to detect the presence of objects. When light is incident on certain objects, it will be partially reflected and partially absorbed. The reflected light is then detected by an optical receiver and a signal is generated to indicate the presence or absence of the object. The analog output provides an voltage signal that is proportional to the reflective light intensity. By setting the sensitivity of the analog output, different objects can be detected.

The OPB702 can be used for a variety of applications, including industrial automation, robotics, medical and inspection equipment, and food processing. It is often used in automated assembly lines to detect when parts are present or missing. It is also used to detect objects of different shapes and sizes, and to track the movement of objects. In robotics, it is used to detect obstacles or changes in the environment, such as the presence of a person or animal. In medical and inspection equipment, it is used to detect defects on surfaces or to measure the size of objects. In food processing, it is used to detect when an item is present or when a new batch starts.

In conclusion, the OPB702 is a type of optical sensor that uses reflection to detect the presence or absence of an object. It utilizes the photo-electrical effect to detect light intensity and provides an analog output signal that is proportional to the reflective light intensity. It can be used for a variety of applications, such as industrial automation, robotics, medical and inspection equipment, and food processing.
