[0002] The through-beam photoelectric switch includes a transmitting component and a receiving component. Light is used as the transmission medium between them. Through the action of the photodiode, the transmitting end sends out a light signal, and the receiving end receives the light signal. When the light emitted by the transmitting end is blocked by an object and cannot be transmitted to the receiving end, the receiving end will output a signal to feedback that an object has passed. This through-beam photoelectric switch can be divided into short-range, medium-range, and long-range according to its use, and can be divided into red light and infrared light according to the wavelength of the transmitting end. It is widely used to detect people, goods, and machinery and equipment. It has the advantages of high accuracy, fast response, and non-contact. Therefore, it is widely used in modern industrial production and logistics fields.

[0007] The preferred technical solution is: a first lens is provided on the front side of the shell, and the first lens and the first LED lamp bead are arranged correspondingly; a second lens is provided on the rear side of the shell, and the second lens and the second LED lamp bead are arranged correspondingly.

[0008] A preferred technical solution is: an indicator light is also provided on the housing, the indicator light is connected to the control module, and the indicator light is configured to determine whether the photoelectric switch operates normally.
