WebPhotoelectric Sensors detect objects, changes in surface conditions, and other items through a variety of optical properties. A Photoelectric Sensor consists primarily of an Emitter for emitting light and a Receiver for receiving light. When emitted light is interrupted or reflected by the sensing object, it changes the amount of light that ... WebNo, LED lights do not work with photocells. LED Lights are not compatible with photocell fixtures since the electric current flows through the lamps constantly. This is because photocells require some power to know if it’s dawn or dusk. Moreover, average photocells can’t work during the day when the light is turned off without a small current.
