A laser photoelectric switch usually consists of\na laser, a lens and a receiver. The laser emits a laser beam, which is focused\nby the lens and irradiates the receiver. When the laser beam is blocked by an\nobject, the signal strength received by the receiver changes, and the trigger\ncircuit sends out a signal or controls the circuit. Compared with traditional\nphotoelectric switches, laser photoelectric switches have higher detection\naccuracy and sensitivity, and can detect very small object movement and\nocclusion. At the same time, the laser photoelectric switch also has higher\nreliability and stability, and can work normally in harsh environments.
