What is a Photoelectric sensor?

Photoelectric sensors are sensors that detect light such as visible light, infrared rays, and ultraviolet rays. The surface shape and condition of the object to be measured, constituent substances, etc. are inspected using the properties of light. Since it can detect surface shape and constituent substances without contact, it is suitable for pre-shipment inspection and non-destructive inspection equipment. It also features long distances, short response times, and high resolution. Detection methods include transmission type, regression reflection type, and diffuse reflection type.

Application of Photoelectric sensor

Photoelectric sensors are used in a wide range of fields such as food and consumer products, electrical equipment, production factories such as automobiles, equipment of facilities such as buildings and condominiums, public institutions such as railways, and laboratory equipment. In production factories, it is used for inspections, etc. by taking advantage of the characteristic that objects can be measured without contact. In facility equipment and public institutions, it is used as a sensor for devices that operate by detecting people, such as automatic doors and ticket gates. In laboratory equipment, it is non-destructive and is used for structural analysis and thickness measurement of the measurement target.
