Safety light curtains

Safety light curtains are photoelectric sensors that create an invisible light barrier around a safety area. They operate by detecting interruptions in an infrared beam network, triggering the machine to immediately enter a safe state. Safety light curtains are widely used in industrial applications, particularly for safeguarding robotics and automation equipment, where they prevent personnel from accessing hazardous areas and enhance workplace safety without physical barriers.
