The photoelectric switch sensor is the abbreviation of the photoelectric proximity switch. It uses the shielding or reflection of the light beam by the detected object, and the circuit is connected by the synchronous loop to detect the presence or absence of the object. When the photoelectric switch sensor outputs the signal, the signal will occasionally be unstable, and many people don't know why. Today, the editor will explain to you the reasons for the unstable output of the photoelectric switch sensor and the corresponding solutions:

The following situations may cause the output signal of the photoelectric switch sensor to be unstable when detecting the object:
1. The power supply is abnormal.
2. The detection frequency is too fast.
3.The problem of the size of the measured object.
4. The measured object is not in the stable detection area of ​​the sensor.
5. Electrical interference.
Countermeasures:
1. Supply a stable voltage to the photoelectric switch sensor, and the supplied current must be greater than the current consumption of the sensor.
2. The passing speed of the measured object must be slower than the response speed of the sensor.
3.The size of the measured object must be larger than the standard detection object or small detection object.
4.The object to be measured must be detected within the stable detection range of the sensor.
5. Corresponding protective measures can be taken, such as: making a shielding cover around the probe, grounding high-power equipment, etc.
When using the photoelectric switch sensor, you should also pay attention to avoiding dusty places as much as possible; places with more corrosive gases; places where water, oil, and chemicals may splash directly; outdoors or sunlight, etc. Places with shading measures; places where the ambient temperature changes beyond the specified range of the product; places where vibration and shock are large, but no shock-absorbing measures are taken. In order to avoid malfunction of the photoelectric switch sensor.
