Safety light curtains protect robotic arms during safe operation.

In modern intelligent manufacturing, the high-speed operation and high-precision tasks of robotic arms have greatly improved industrial efficiency, but they also carry safety risks such as personnel intrusion and collisions. To ensure the dual safety of operators and equipment, safety light curtains have become one of the important protective devices for robotic arms.

By installing safety light curtains around the robotic arm’s working area, an “invisible safety barrier” can be formed. Once personnel or foreign objects enter the light curtain detection area, the system immediately sends a signal and triggers the robotic arm to stop or slow down, effectively preventing safety accidents. Meanwhile, some advanced safety light curtains can also control different action zones according to preset logic, achieving more refined risk protection and process management.

Compared with traditional fences, light curtains not only save space but also have advantages such as high sensitivity, fast response, and easy integration, making them an ideal solution to balance safety and efficiency for robotic arms. The application of safety light curtains has become an indispensable safety guarantee in smart factories.

Safety light curtains have the following three major advantages in industrial applications:

1. High sensitivity response, real-time protection

Safety light curtains quickly detect objects entering dangerous areas through infrared beams, with a response time usually less than 20ms, able to immediately trigger a stop when personnel approach hazardous parts, effectively preventing accidents.

2. Space-saving and flexible deployment

Compared with traditional fences, safety light curtains do not occupy additional physical space, especially suitable for scenarios with limited space or frequent access to work areas. They can be freely combined and installed to adapt to various industrial environments.

3. Easy integration and simple maintenance

Safety light curtains can be easily connected to industrial control systems, supporting multiple control interfaces and function settings, facilitating cooperation with PLCs, robots, and other equipment. At the same time, their simple structure results in low failure rates and minimal maintenance costs.
