Quizplus · Accepted Answer

LEDs are the most commonly used light source in industrial photoelectric sensors due to their reliability, durability, and low power consumption. They are also small in size and generate very little heat, making them ideal for use in small sensors. Phototransistors, photovoltaic cells, and miniature incandescent lamps are not commonly used as light sources in industrial photoelectric sensors.
