FAQ
1 ,How does the photoelectric switch sensor work?
The photoelectric switch is composed of transmitter, receiver and detection circuit. The transmitter aims at the target and emits a beam, which generally comes from a semiconductor light source, light-emitting diode (LED), laser diode and infrared emitting diode. The beam is emitted without interruption, or the pulse width varies. The radiation intensity of the pulse-modulated beam is selected many times in the emission and does not run indirectly towards the target. The receiver is composed of a photodiode or phototriode and a photocell.
