[0002] Safety light barriers are photoelectric safety protection devices. In modern factories, people and machines work together. Safety light barriers are installed on some potentially dangerous mechanical equipment, such as hydraulic machinery, shearing equipment, metal cutting equipment, etc., to ensure the personal safety of workers.
