Optical sensors are used to detect variations in light intensity or changes in an object\'s color or shape. Phototransistors are a type of optical sensor that can detect photons of light and convert them into an electric current. The OP800B phototransistor is a more advanced type of phototransistor that has a wide range of applications in industrial, consumer, and medical sectors. In this article, we will explore the application fields and working principle of the OP800B phototransistor.

Application Fields of OP800B Phototransistor

The OP800B phototransistor is a versatile and reliable photodetector that can be used in many different applications. It is particularly well-suited to security and surveillance systems, automatic door opening and closing systems, medical equipment, and automotive headlights. Additionally, OP800B phototransistors can be used in industrial automation systems to detect objects and detect other environmental changes.

The OP800B has a built-in filter that makes it very sensitive to light in the visible spectrum, making it well-suited to applications where detecting small changes in light intensity is important. Additionally, the device’s built-in digital output allows for easy integration into existing networks and systems.

Working Principle of OP800B Phototransistor

OP800B phototransistors are a type of optoelectronic transducer, which means they convert physical phenomena (light) into an electrical signal. When a photon of the correct frequency hits the OP800B’s active area, it is converted into an electron-hole pair, which results in an electric current. This current is then amplified and sent to an output for further processing.

The OP800B is designed to operate in two modes. In the light-activated mode, the device is triggered when it detects a photon of light. In the dark-activated mode, the device is triggered when it fails to detect a photon of light. This makes the OP800B suitable for applications that require either active or passive detection of objects or changes in the environment.

Conclusion

The OP800B phototransistor is a versatile and reliable photoelectric transducer that can be used for a multitude of applications in industrial, consumer and medical sectors. Its wide range of applications includes security and surveillance systems, automatic door opening and closing systems, medical equipment, and automotive headlights. Additionally, its two-mode operation makes it suitable for applications that require either active or passive detection of objects or changes in the environment.
