Description

Technical Field

[0001] The utility model relates to the field of protective devices, in particular to a protective device for a reflective plate of a photoelectric sensor. Background Art

[0002] A photoelectric sensor is a device that converts light signals into electrical signals. Its operating principle is based on the photoelectric effect, which occurs when light strikes a substance and its electrons absorb the energy of photons, generating a corresponding electrical effect. Photoelectric effects are categorized into three types based on their properties: external photoelectric effect, internal photoelectric effect, and photovoltaic effect. Examples of photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, and photocells.

[0003] Photoelectric sensors are widely used in industrial automation and detection systems, particularly in production lines and logistics conveyors. Reflective photoelectric sensors rely on light reflection from reflectors to detect the presence of objects. However, in certain environments, the reflectors can be damaged by accidental impacts from objects being detected, compromising sensor operation. Currently, there is a lack of protective devices specifically designed to protect the reflectors of photoelectric sensors, which compromises operational stability. Therefore, a protective device for the reflectors of photoelectric sensors is needed to ensure reliable sensor operation. Utility Model Content
