Light curtains, also known as safety light barriers or optoelectronic protective devices, are essential components in industrial automation for safeguarding personnel and machinery. These devices consist of a transmitter and receiver pair that create an invisible infrared light grid. When any object, including a human hand or body part, interrupts this grid, the system sends a signal to halt the machine, preventing accidents. Light curtains are characterized by parameters such as resolution (e.g., 14mm, 30mm for finger or hand protection), protective height, range, and response time. They are typically available in Type 2 or Type 4 safety categories per IEC 61496, with Type 4 offering the highest level of reliability for critical applications. These devices can be configured with muting, blanking, and cascading functions to adapt to complex production lines.
Light curtains are widely deployed in sectors such as automotive manufacturing, packaging, metalworking, and robotics. They are installed on assembly lines, press brakes, welding stations, and automated guided vehicles (AGVs). Their primary role is to create a safe perimeter around hazardous machinery without physical barriers, allowing for easy access and material flow while ensuring operator safety. They are also used in cleanrooms and food processing environments where hygiene and minimal contact are critical.
Within our catalog, you will find subcategories including safety light curtains for finger protection (resolution 14mm), hand protection (resolution 30mm), and body protection (resolution 50mm or more). Key article codes follow a structured format, such as SLC-14-600 for a 14mm resolution curtain with 600mm protective height, or SLC-30-1200 for a 30mm resolution curtain with 1200mm height. Other common codes include SLC-50-1800 for body protection. These codes typically include the resolution, protective height, and sometimes the safety type (e.g., SLC-4-14-600 for Type 4). Accessories like mounting brackets, cables, and alignment aids are also available.
