Information

The photoelectric switch sensor uses light beams such as near infrared and infrared to detect and distinguish objects. The weak light beams instantly emitted by the photoelectric device can be safely, reliably and accurately emitted and received. The photoelectric switch sensor manufacturer tells you that light is an electromagnetic wave with a transmission speed of about 300,000 kilometers per second. It is received by it at the moment of transmission, so that the sensor responds quickly.

The important function of the photoelectric switch is to be able to deal with the change of light intensity: the photoelectric switch sensor manufacturer tells you that it uses optical elements to change the light beam in the middle of the propagation medium; uses the light beam to reflect the object; makes the light beam return instantaneously after a long distance. The photoelectric switch sensor manufacturer tells you that the photoelectric switch is composed of three parts: transmitter, receiver and detection circuit. The transmitter is aimed at the target to emit a beam, and the emitted beam generally comes from a light-emitting diode (LED) and a laser diode. The photoelectric switch sensor manufacturer tells you that the beam is emitted uninterruptedly, or the pulse width is changed. The radiation intensity of the pulsed beam has been selected many times in the launch, and it runs towards the target without indirectly.
The receiver is composed of a photodiode or phototransistor. The photoelectric switch sensor manufacturer tells you that there are optical components such as lens and aperture on the front of the receiver. Behind it is the detection circuit, which can filter out the effective signal and apply the signal.
