The following conditions may cause no output after the customized photocell sensor detects an object:
1. Incorrect wiring or configuration: The through-beam photocell sensor must be used in combination with the light-emitting part and the light-receiving part, and both ends need to be powered; the retro-reflective type must be used in combination with the sensor probe and the retro-reflective plate.
2. Incorrect power supply: The customized photocell sensor must be supplied with a stable power supply. If it is a DC power supply, the positive and negative poles must be confirmed.3. The detected object is not within the detection area of the photocell sensor. The detected object must be within the area that the sensor can detect.
4. The optical axis of the customized photocell sensor is not aligned: the optical axis of the light-emitting part and the light-receiving part of the through-beam type must be aligned; the probe part of the retro-reflective type must be aligned with the optical axis of the reflector.
5. The detection object of the customized photocell sensor does not meet the detection object standard. Different types of sensors have different requirements for the size, color, detection distance, etc. of the corresponding detection object.
6. Environmental interference and electrical interference: The light intensity cannot exceed the rated range. There is dust in the on-site environment, and the probe surface of the customized photocell sensor needs to be cleaned regularly; multiple sensors are closely installed, which will cause interference with each other. There are high-power devices around the customized photocell sensor, and corresponding anti-interference measures must be taken when interference occurs.
