How to identify the detectable range of various photoelectric sensors? 1

To identify the detectable range of various photoelectric sensors, it is necessary to first understand the working principle and classification of photoelectric sensors. A photoelectric sensor is a type of sensor that converts light signals into electrical signals, and its detection range depends on the type, design, and light source used in the sensor. Here are some common types of photoelectric sensors and their detection range identification methods:diode

1. Through photodiode sensors:

This type of sensor is typically used to detect changes in the intensity of light. The detection range depends on the spectral response of the BZX84-B5V1 diode, typically in the infrared, visible to ultraviolet range. To identify its detection range, you can refer to the response curve in the product specification book to determine its operating wavelength.diode

2. Through phototransistor sensors:

Phototransistors provide a more sensitive response than photodiodes. The detection range can also be determined by examining the spectral response curve, while considering the impact of magnification on sensitivity.diode
