OPTEX Sensor Product Features

working principle Mirror reflection photoelectric sensor

Or reflect the infrared beam through an object or mirror, and the photoelectric sensor receives the reflected beam to determine the presence of the object based on the strength of the beam. There are also many types of infrared photoelectric switches, generally including mirror reflection photoelectric switches, diffuse reflection switches, slot switches, reflective switches, fiber optic switches, and other main types. The selection of fast and easy automation for photoelectric switches is included.

Different photoelectric switches are used in different situations, such as fiber optic photoelectric switches commonly used in electromagnetic vibration feeders, diffuse reflection photoelectric switches commonly used in the supply of packaging film in intermittent packaging machines, and slot type photoelectric switches commonly used in continuous high-speed packaging machines.

The commonly used infrared photoelectric switch utilizes the principle of reflection of near-infrared beams by objects, and detects the presence or absence of objects by sensing the strength of the reflected light through a synchronous circuit. The photoelectric sensor outputs the infrared beam to

Optoelectronic switches have been used in various fields such as crop position detection, liquid level control, product counting, width discrimination, speed detection, fixed length cutting, hole recognition, signal delay, automatic door sensing, color code detection, punching and shearing machines, and safety protection. In addition, by utilizing the concealment of infrared radiation, it can also be used for anti-theft surveillance in banks, warehouses, shops, offices, and other necessary places.
