(Summary description)The Chinese manufacturer tells you that the Photoeye sensor is also called a photoelectric detection sensor (commonly known as photoelectric head, photoelectric eye). It uses the principle of light emission and reception to emit modulated light, receive the reflected light of the object under test, and distinguish the difference according to the strength of the received light signal. Color, or to determine the presence or absence of an object. It realizes the color mark detection by comparing with the non-color mark area, rather than direct measurement.

Color, or to determine the presence or absence of an object. It realizes the color mark detection by comparing with the non-color mark area, rather than direct measurement.

Photoeye sensor
How to choose color mark and color sensor. In the automatic control system of flexible packaging machinery, printing machinery, food machinery, textile and paper machinery, etc., the Photoeye sensor is used in conjunction with other circuits or devices to control the color code printed on a certain color background, or other pattern colors that can be used as marks. Detecting the presence or absence of block and line objects can realize functions such as automatic positioning, fixed length, color discrimination, deviation correction, plate matching, and counting.
According to light source classification, Photoeye sensor can be divided into incandescent lamp sensor and monochromatic light source sensor. ⑴ Incandescent lamp sensor The sensor based on the incandescent lamp uses a colored light source to detect the color. This kind of incandescent lamp emits light of various colors including infrared light, so the sensor using this light source can detect small changes in color in a wide range. In addition, the detection circuit of the incandescent lamp sensor is usually very simple, so an extremely fast response speed can be obtained. However, the incandescent lamp does not allow vibration and prolonged use time, so it is not suitable for occasions with severe shock and vibration.
