German POWER LIMIT sensor, POWER LIMIT model, POWER LIMIT price

POWER LIMIT sensor is a device that converts optical signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon where electrons in a material absorb the energy of photons when light strikes certain substances, resulting in corresponding electrical effects. Based on the different manifestations of the photoelectric effect, it is classified into three categories: external photoelectric effect, internal photoelectric effect, and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, and solar cells. The performance and characteristic curves of photoelectric devices are analyzed. PO
