Optical Sensors have been around for decades and are used by a variety of industries for applications such as searching for foreign objects in manufacturing, detecting motion, and reading barcodes. Phototransistors are one type of optical sensor that is commonly used in these applications. BP 103-3 is a particular type of phototransistor that has become increasingly popular in recent years. This article will discuss the application field and working principle of the BP 103-3.

The BP 103-3 offers a broad application field with a wide range of uses. It is a surface mount device specifically designed for sensing and controlling high-speed LED or infrared emitter sources. Its low operating voltage and high switching speed make it ideal for use in motion control applications. It is also used in various infrared applications like game controllers and remote controls with its excellent speed and low noise. Furthermore, the BP 103-3 can be used for encoding applications due to its low-cost and simplicity.

The BP 103-3 phototransistor is designed to detect weak optical signals. Its working principle is based on the principle of photovoltaic conversion. When a transparent LED or infrared emitter is powered, the light produced by the source is directed towards the BP 103-3. A photovoltaic effect then occurs as the photons from the light are absorbed by the phototransistor. This absorption causes the BP 103-3 to produce a current, which is then used to control or send out signals for a variety of applications.

In summary, the BP 103-3 is a popular type of phototransistor used in a variety of applications. Its broad application field and simple design allow it to be used in motion control and encoding projects. Its low power requirements and high switching speed make it well suited for infrared applications such as game controllers and remote controls. Finally, its working principle is based on the photovoltaic effect, which allows it to detect extremely weak optical signals. The BP 103-3 is an invaluable part of the optical sensing world.
