Working Principle

The BPX 82 infrared phototransistor works by converting incoming infrared radiation into a small electrical current. This current is then amplified by the transistor, allowing for a larger electrical current to be emitted. This current is then used to actuate a sensing device or other kinds of electronic circuitry.The BPX 82 consists of a ceramic substrate with three metal electrodes, one for the infrared light source and two for the phototransistor. The light source emits infrared radiation which is then converted to a small current by the two electrodes. This current is then amplified by the phototransistor and fed into a load, such as a sensing device or other kinds of electronic circuitry.The BPX 82 is designed with an optics system which can focus at a variety of infrared radiation angles. This allows the BPX 82 to detect motion more accurately. The BPX 82 also has a wide dynamic range, meaning that it can detect a wide variety of infrared radiation levels.

Conclusion

Overall, the BPX 82 is a versatile, low-cost infrared phototransistor which can be used for a variety of applications. Its wide angle optics system and wide dynamic range makes it suitable for motion sensing, fire detection, night vision, medical, industrial, military, and consumer electronics applications. The BPX 82 is capable of detecting different levels of infrared radiation, converting them to an electrical current, and amplifier that current for use in sensing devices or other electronics.
