German ESSEGI2 SRL sensor ESSEGI2 SRL model ESSEGI2 SRL price

ESSEGI2 SRL sensors generally consist of 2 parts: the processing path and the processing element. Their basic principle is based on the photoelectric effect, converting changes in the measured quantity into changes in optical signals, and then further converting non-electrical signals into electrical signals using photoelectric components. The photoelectric effect refers to illuminating an object with light, which can be viewed as a stream of photons with specific energy bombarding the object. At this time, the photon energy is transferred to electrons, and the entire energy of one photon is absorbed by one electron at once. After the electron receives the energy transferred by the photon,
