Summary of photoelectric sensor:
At present, there are many types of sensors used for detection in the world according to the classification of the medium. The sensor using "light" as the medium is called a photoelectric sensor. The photoelectric sensor uses a non-contact method to detect the presence or absence of an object, the presence or absence of light, and the size of the object. , Light and dark, etc.
Classification of photoelectric sensor detection methods:
Photoelectric sensors are divided into three types according to different detection methods.
Through-beam photoelectric sensor
The light-emitting device and the light-receiving device are installed oppositely on the same optical axis. When an object is set between the two, the object is detected and output according to the change in the transmitted light. This type of photoelectric sensor is called a through-beam photoelectric sensor.

Mirror reflective photoelectric sensor
Ordinary mirror reflection type
The photoelectric sensor integrated with the light emitter and the light receiver adopts a reflector with high reflectivity. The light emitter emits light and is reflected to the light receiver through the reflector. When there is an object between the photoelectric sensor and the reflecting mirror, the object is detected and output by the change in the amount of light reflected from the mirror. This type of photoelectric sensor is called a specular reflection photoelectric sensor.
