When using the customized photoelectric beam sensor to detect the distance between objects, the problem that many users may encounter is that there is no output signal after the photoelectric sensor detects the object. There are many reasons why the sensor does not output after detecting the object. Let's take a look.
The first thing that needs to be considered is the problem of customized photoelectric beam sensor wiring and equipment. Regarding the through-beam sensor, the light-emitting part and the light-receiving part need to be used in combination to produce the effect, and both ends need to be powered. The diffuse sensor requires a combination of sensor probes and a retro-reflector. Therefore, it is necessary for the user to provide a stable power supply to the customized photoelectric beam sensor. If the DC power supply is used, the faulty connection of the positive and negative poles will also cause the sensor to have no output signal.

Secondly, it is necessary to ensure that the orientation of the detected object must be within the area that the sensor can detect. Misalignment of the optical axis of the customized photoelectric beam sensor can also cause the output signal to disappear. In addition, the size and color of the detected object do not meet the specifications, which will also cause the sensor to fail to detect the passing object well.
Different detection environments will also have a certain impact on the customized photoelectric beam sensor. The light intensity cannot exceed the extra scale. If there is dust in the field environment, the appearance of the sensor probe needs to be cleaned regularly. If multiple sensors are tightly installed, they may interfere with each other. Another major influence is electrical interference. If there is high-power equipment around the customized photoelectric beam sensor, it is necessary to take corresponding anti-interference measures. If these reasons are checked up one by one and there is still no signal output, it is recommended that a professional be checked and repaired.
