The photoelectric beam sensor refers to a sensor that uses photoelectric elements to detect the presence of objects and changes in surface conditions. It is generally composed of three parts: a transmitter, a receiver, and a detection circuit. The working principle of the photoelectric beam sensor is to first convert the measured change into The change of the optical signal converts the change of the optical signal into a change of the electrical signal.

Features of photoelectric beam sensor:
1. Long detection distance
If the detection distance of 10m or more is reserved in the through-beam type, other detection methods (magnetic, ultrasonic, etc.) can be realized that cannot be separated from the detection.
2. Less restrictions on detecting objects
The photoelectric beam sensor manufacturer tells you that because the detection principle is based on the shading and reflection caused by the detection object, it is not like a proximity sensor that limits the detection object to metal, it can be used for glass. plastic. wood. Almost all objects such as liquids are detected.
3. Short response time
The light itself is high-speed, and the circuit of the sensor is composed of electronic parts, so no mechanical working time is included, and the response time is very short.
4. High resolution
The photoelectric beam sensor manufacturer tells you that it is possible to concentrate the projected light beam on a small spot through advanced design technology, or to form a special light-receiving optical system to achieve high resolution. It can also detect small objects and high-precision position detection.
5. Can realize non-contact detection
The photoelectric beam sensor manufacturer tells you that it can detect without mechanically touching the detection object, so it will not cause damage to the detection object and sensor. Therefore, the sensor can be used for a long time.
6. Achievable color discrimination
The photoelectric beam sensor manufacturer tells you that the reflectance and absorptivity of the light formed by the detection object differs according to the wavelength of the light being projected and the color combination of the detection object. Using this property, the color of the detected object can be detected.
7. Easy to adjust
The photoelectric beam sensor manufacturer tells you that in the type of projected visible light, the projected light beam is visible to the eyes, which is convenient for adjusting the position of the detected object.
