Top Safety Light Curtain Applications

Posted on November 21, 2023 gabriel adams Aerospace

In the realm of industrial safety, it is crucial to safeguard the well-being of both workers and the machinery they operate. One innovative and effective solution for this purpose is the utilization of light curtains, as these ingenious devices have witnessed a significant evolution over the years where they now find themselves integral to numerous industrial processes. In this blog, we will explore the top applications of safety light curtains, shedding light on their importance in ensuring safety in the manufacturing and industrial sectors.

Automated Machinery Safety

Light curtains are not often discussed when securing automated machinery, though they are quite useful for various applications. These devices, comprising an array of synchronized photoelectric sensors, emit a grid of invisible infrared beams. When an object, such as a hand, disrupts these beams, the light curtain instantly detects the intrusion and triggers an emergency stop, preventing potential injuries or damage to the machinery. Whether it is a CNC machine, robotic assembly line, or conveyor belt system, light curtains act as a safeguard, offering reliable protection against mishaps.

Robotics and Collaborative Robots

With the rise of robotics in industrial applications, the need for worker safety during human-robot collaboration has become paramount. Light curtains, in this context, serve as a non-intrusive, non-contact safety solution. When a worker approaches a robot's workspace, the light curtain detects their presence and prompts the robot to slow down or stop, allowing for safe interaction. This collaborative effort between humans and robots minimizes the risk of accidents and enhances productivity. As a result, industrial light curtains are indispensable to human-robot collaboration.

Access Control and Perimeter Guarding

Industrial safety extends beyond machinery and robots to the overall workplace environment. For example, light curtains are frequently used to create access control and perimeter guarding systems. They define restricted areas, such as hazardous zones or high-risk workspaces, and employees can only access these areas when the light curtain signals their entry is safe. In essence, light curtains act as digital sentinels, ensuring that unauthorized access is prevented, thus safeguarding the well-being of a workforce.

Conveyor Systems

Conveyor systems are the arteries of many manufacturing facilities, transporting raw materials and products throughout the production process. Ensuring the safety of employees working near these systems is crucial, and light curtains create safe zones around conveyors. When an object or body enters the defined area, the light curtain sends a signal to halt the conveyor's operation immediately, averting potential accidents and injuries.

Packaging and Palletizing Applications

In the packaging and palletizing industry, light curtains offer a multifaceted safety solution. They ensure the safety of workers by creating detection zones around packaging machines and robotic palletizers. If a worker or an object enters these zones, the machine halts, preventing accidents. Furthermore, light curtains are used to count and position products accurately, making them a key component of precision and efficiency in the packaging process.

Metalworking and Press Brakes

Metalworking and press brake applications use light curtains to protect operators, as these machines exert immense force and require operators to be close during setup and operation. Light curtains ensure that the operator's hands and body are kept at a safe distance from moving parts. Any intrusion into the danger zone results in an immediate machine stop, preventing potentially catastrophic injuries.

Woodworking and Sawing Machines

Sawing machines in the woodworking industry can be extremely dangerous if not operated carefully. As such, industrial light curtains are employed to create safety barriers around these machines, ensuring that operators and bystanders are kept out of harm's way. The moment a person crosses the light curtain, the saw automatically stops, averting the risk of severe injuries.

Food Processing and Packaging

Food processing and packaging industries have strict hygiene and safety standards to meet, and light curtains, often made with specialized materials to meet these standards, are utilized in various capacities to enhance worker safety while preventing contamination. For instance, light curtains ensure that a packaging machine's doors remain closed during operation, preventing access to the inside. This not only enhances safety, but also maintains the integrity of the food product.

Medical and Pharmaceutical Manufacturing

In the highly regulated fields of medical and pharmaceutical manufacturing, precision and safety are of paramount importance. Light curtains are used to create controlled access zones in cleanrooms and sterile environments, and these curtains guarantee that only authorized personnel enter designated areas to maintain the integrity of the manufacturing process and ensure the safety of products.


In conclusion, industrial safety is a paramount concern in countless applications, and light curtains have emerged as invaluable tools for protecting workers and machines in various settings. From automated machinery to collaborative robotics, light curtains are versatile devices with a broad spectrum of uses. By embracing light curtains, industries can enhance workplace safety and increase productivity and efficiency.
