For your answer, what are the reasons for the unstable output signal of the photoelectric sensor? The following situations may cause the photoelectric sensor to detect the wrong action of the object: ① Electrical interference; ② Abnormal power supply; ③ The size of the object to be measured; ④ The measured object is not in the stable detection area of the sensor; ⑤ The detection frequency is too fast. Countermeasures: ① Supply a stable voltage to the sensor, and the supplied current must be greater than the current consumption of the sensor; ② The size of the measured object must be larger than the standard detection object or a very small detection object; ③ The passing speed of the measured object must be slower than the response speed of the sensor; ④ The measured object must be detected within the stable detection range of the sensor; ⑤ Corresponding protective measures can be taken, such as: shielding protective covers around, grounding high-power equipment, etc.
