Safety light curtains, also known as light guards or optoelectronic protective devices, are not a specific brand but a category of safety products used in industrial automation. These devices are manufactured by various companies worldwide, such as Sick AG (Germany), Omron (Japan), and Banner Engineering (USA). They are primarily used in manufacturing and processing industries to protect workers from hazardous machinery by creating an invisible infrared beam barrier. When the beam is interrupted, the machinery stops, preventing accidents. Key products include Type 2 and Type 4 safety light curtains, which vary in safety performance and application complexity.
