(1) Fork photoelectric sensor
Placing an optical transmitter and a receiver facing each other on either side of a slot is a fork photoelectric. The luminaire emits infrared or visible light, and the light receiver receives the light in an unobstructed condition. However, when the detected object passes through the slot, the light is blocked and the photoelectric switch is activated. A switch control signal is output to cut off or turn on the load current, so as 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) Thru-beam photoelectric sensor
By separating the luminaire from the receiver, the detection distance can be increased. The photoelectric switch composed of a light emitter and a light receiver is called a through-beam split photoelectric switch, referred to as a through-beam photoelectric switch. Its detection distance can reach several meters or even tens of meters. When in use, the luminaire and the receiver are respectively installed on both sides of the path through which the detector passes, and when the detector passes through the optical path, the receiver outputs a switch control signal.
(3) Reflector type photoelectric switch
The reflector and the receiver are installed in the same device, a reflector is installed in front of it, and the photoelectric control function is completed by using the reflection principle to complete the photoelectric control function is called the reflector reflection (or mirror reflection type) photoelectric switch. Under normal circumstances, the light emitted by the luminaire is reflected back by the reflector and received by the receiver; Once the optical path is blocked by the detected object and the receiver cannot receive light, the photoelectric switch will operate and output a switch control signal.
(4) Diffusion reflection photoelectric switch
It also has a light emitter and a light collector in the detection head, but there is no reflector on the front. Under normal circumstances, the light emitted by the luminaire cannot be found by the receiver. When the light is blocked by the detector and partially reflected back, the receiver receives the light signal and outputs a switching signal.
