First, it is the problem of wiring or configuration to be considered. For the through-beam BANNER photoelectric sensor, it must be used in combination with the light emitting part and the light receiving part, and both ends need to be powered by power; The regression reflector type must be used in combination with the sensor probe and the regression reflector; At the same time, the user must provide a stable power supply to the sensor, and in the case of DC power supply, the positive and negative poles must be confirmed, if the positive and negative poles are connected incorrectly, the output signal will not be available.
Second, the above reason analysis is the consideration of the BANNER Banner photoelectric sensor itself, we also need to consider the position of the detected object, if the detected object is not in the detection area, such a detection is futile. The object to be detected must be within the area that the sensor can detect, that is, within the range that the photoelectric can perceive. Secondly, it is necessary to consider whether the optical axis of the sensor is aligned, the optical axis of the projector and the light receiving part of the beam type must be aligned, and the corresponding probe part of the regressive reflection type and the optical axis of the reflector must be aligned. It is also necessary to consider whether the detection object meets the standard detection object or the minimum detection object standard, and the detection object cannot be less than the standard of the minimum detection object, so as to avoid causing the through-beam type and reflection type to not be able to detect transparent objects well, and the reflective type has requirements for the color of the detected object, the darker the color, the closer the detection distance.
3. If the above situations can be clearly ruled out, what we need to do is to detect the interference factors of the environment. For example, the light intensity cannot exceed the rated range; If there is dust in the field environment, we need to regularly clean the surface of the BANNER photoelectric sensor probe; Or multiple sensors are closely mounted and interfere with each other; There is also a greater impact is electrical interference, if there are high-power equipment around, there must be corresponding anti-interference measures when interference occurs. If you have done the above checks one by one, these factors can be clearly ruled out or there is no signal output, it is recommended to return to the manufacturer for testing and judgment.

Banner Sensors – The basic building blocks of fiber optic sensors
There are three basic components of a fiber optic sensor network, one of which is called a single-point sensor. An optical fiber only plays the role of transmission here, and the other is called a multi-point sensor, where an optical fiber strings many sensors together, so that many sensors can share a light source to achieve networking.
