P+F Pepperl+Fuchs photoelectric sensor serves the industrial control industry economy

Pepperl+Fuchs photoelectric sensor photoelectric switch has also been applied in many aspects, such as stroke control, diameter limit, speed detection, air flow control, etc. The detection object must be within the area that the sensor can detect, that is, within the range that the photoelectric can detect. The optical axis of the light emitting part and the light receiving part of the through-beam type must be aligned, and the optical axis of the corresponding retro-reflective probe part and the reflector must be aligned.

The same thing to consider is whether the detection object meets the standard detection object or the minimum detection object standard. The detection object cannot be smaller than the minimum detection object standard, so as to avoid causing the through-beam type and the reflection type to not be able to detect transparent objects well, like the reflection type. The color of the detected object is required. The darker the color, the closer the detection distance. According to the structure, the photoelectric switch can be divided into three types: the amplifier separated type, the amplifier built-in type and the power supply built-in type. The amplifier separation type is to separate the amplifier and the sensor, and is made with a dedicated integrated circuit and a mixed installation process. Because the sensor has the characteristics of ultra-small and multi-variety, the amplifier has more functions. There is a kind of photoelectric sensor, which should belong to Pepperl+Fuchs photoelectric sensor. Relatively speaking, the accuracy of optical fiber sensor is usually higher than that of ordinary photoelectric sensor. Ordinary photoelectric sensor means that the sensor directly emits light and receives light. Due to diffusion and other reasons, the amount of light received cannot be accurately controlled, that is, the accuracy of detection cannot be improved. The optical fiber sensor transmits light through the optical fiber line to increase the degree of beam convergence, and it is easy to judge the amount of light received, and the detection accuracy should be high.
