Fiber optic sensors are a type of photoelectric sensors. Relatively speaking, fiber optic sensors are usually more accurate than ordinary photoelectric sensors. Ordinary photoelectric sensors directly emit and receive light on the sensor. Due to the diffusion of light and other reasons, the amount of light received cannot be accurately controlled, which leads to the inability to improve the accuracy of detection. Fiber optic sensors transmit light through optical fiber lines, improve the degree of light beam convergence, and are easy to judge the amount of light received, so the detection accuracy is high.
