    Market Definition

    Photoelectric sensors detect objects, as well as changes in surface conditions, through their optical properties. They emit light beams (visible or infrared) from their emitters (light-emitting elements) and receive them at receivers (light-receiving elements). When emitted light is interrupted or reflected by the objects to be sensed, the amount of light that arrives at the receivers is changed. These receivers detect this change and convert it to an electrical output. Photoelectric sensors are not limited to detecting metal objects only. For instance, proximity sensors operate on the principle of light being interrupted or reflected by the targeted objects, which can be glass, plastic, wood, or liquid. Various types of photoelectric sensors, including through beam, retroreflective, and reflective, are used in numerous applications, such as consumer electronics, industrial manufacturing, and food & beverages. The photoelectric sensor market is diversified, with the presence of various established, as well as emerging players operating across its value chain.
