The following conditions may cause the photoelectric sensor to detect that the output signal is unstable:

1 The power supply is abnormal;

2 detection frequency is too fast;

3 measured object size problem;

4 The measured object is not in the sensor stability detection area;

5 electrical interference.

Countermeasures:

1 to the sensor for a stable voltage, the current must be greater than the current consumption of the sensor;

2 The speed at which the measured object passes must be slower than the response speed of the sensor;

3 The size of the object to be measured must be greater than the standard detection object or the minimum detection object;

4 The measured object must be detected within the stable detection range of the sensor;

5 can do the appropriate protective measures, such as: shielding shield around the probe, grounding high-power equipment and so on.
