The photoelectric beam sensor manufacturer tells you that with the advancement of science and technology and the popularization of intelligence, the photoelectric sensor has also ushered in its spring. The photoelectric beam sensor manufacturer tells you that in this rapidly developing society, photoelectric sensors have begun to be widely recognized and used by people due to their high-quality characteristics. But for many people, they still don't know the photoelectric sensor or the classification of the photoelectric sensor. Today, the photoelectric beam sensor manufacturer will introduce the photoelectric sensor and its classification.

Everyone may know that a photoelectric sensor is a sensor that uses a photoelectric element as a detection element. It first converts the measured change into a change in an optical signal, and then further converts the optical signal into an electrical signal with the help of photoelectric elements. The classifications are as follows:
1. Slot-type photoelectric sensor
A light emitter and a receiver are mounted face to face on both sides of a slot is a slot-shaped photoelectric. The photoelectric beam sensor manufacturer tells you that the light emitter can emit infrared light or visible light, and the light receiver can receive light without obstruction. But when the detected object passes through the slot, the light is blocked, and the photoelectric switch is activated. Output a switch control signal to cut off or switch on the load current to complete a control action. The detection distance of the slot switch is generally only a few centimeters due to the limitation of the overall structure.
2. Through-beam photoelectric sensor
If the light-emitting device and the light-receiving device are separated, the detection distance can be increased. The photoelectric switch composed of a light emitter and a light receiver is called a through-beam separate photoelectric switch, or a through-beam photoelectric switch for short. The photoelectric beam sensor manufacturer tells you that its detection distance can reach several meters or even tens of meters. When in use, the light emitter and the light receiver are respectively installed on both sides of the passing path of the detected object, and the light path is blocked when the detected object passes, and the light receiver acts to output a switch control signal.
3. Reflective plate type photoelectric switch
The light-emitting device and the light-receiving device are installed in the same device, a reflector is installed in front of it, and the photoelectric control function is completed by the principle of reflection, which is called the reflector reflection type (or mirror reflection type) photoelectric switch. The photoelectric beam sensor manufacturer tells you that under normal circumstances, the light emitted by the illuminator is reflected by the reflector and received by the receiver; once the light path is blocked by the detection object and the receiver cannot receive light, the photoelectric switch will act and output one Switch control signal.
4. Diffuse reflection type photoelectric switch
It also has a light-emitting device and a light-receiving device in its detection head, but there is no reflector in the front. Under normal circumstances, the light receiver from the illuminator cannot be found. The photoelectric beam sensor manufacturer tells you that when the detected object blocks the light and reflects the light part back, the receiver will receive the light signal and output a switch signal.
The above is a detailed answer to the types of photoelectric sensors that you have been wondering for a long time. The photoelectric beam sensor manufacturer believes that it can help you better understand the photoelectric sensor!
