Machine safety light curtains are devices used in a variety of different industries to create barriers that protect human workers from potential hazards. The SF2B-H12SL is one such light curtain, and its purpose is to act as a physical barrier and detector to prevent human accidents and injuries. To better understand its working principle and its potential applications, it is important to look at the key components of the SF2B-H12SL.

The SF2B-H12SL is a 24-volt DC, Type 2 light curtain that comes with two receiver cables of 5.3 meters, and two adjustable emitter cables of 30 cm. It has a maximum hand reach of 5 cm, and a sensing height range of 0.3 to 7.1 meters. Additionally, the SF2B-H12SL has an environment immunity rating of IP67, a detection angle of 65°, and a response speed of 150 milliseconds.

The working principle of the SF2B-H12SL is based on alternating infrared emitters and receivers. When someone tries to reach beyond the protected area - no matter what direction - infrared light beams are blocked, and the light curtain’s electromagnetic field triggers an emergency stop. The SF2B-H12SL has various operating modes, such as beam blanking and double beam blanking, that allow it to be adjusted for different workspaces and applications.

As a machine safety light curtain, the SF2B-H12SL can be used to prevent human-machine collisions in a wide range of applications. In the manufacturing industry, it can be used to protect workers from hazardous machines and robots in production lines. Additionally, it can be used in medical environments, such as operating rooms, to prevent doctors and nurses from accidental exposure to electrical shock, radiation, or other hazardous elements. Moreover, the SF2B-H12SL can also be used in other areas, such as logistics and material handling, where personnel must interact with hazardous materials or machines.

In addition to its application as a machine safety light curtain, the SF2B-H12SL has a number of features that make it highly suitable for workshop automation. It has a protective housing that is designed to survive high mechanical shocks and can be directly mounted in production areas. Furthermore, it has wear resistance and a detection range of up to 7 meters, making it perfect for use in conveyor systems and production lines. Additionally, its built-in flexibility means that it can be used with different types of machinery and can be used to automate different aspects of production.

The versatility of the SF2B-H12SL is further enhanced by its programmable logic controller and its various output connections. Its PLC can be integrated into emergency stop systems and run automated processes such as door opening/closing. Furthermore, its outputs can be connected to programmable controllers in automated workstations or can be used to control safety light curtains to create larger protected areas.

Overall, the SF2B-H12SL is a high-performance machine safety light curtain designed to protect personnel from potentially hazardous machines and robots. Its adjustable emitter and receiver cables, adjustable hand reach, high shock resistance, and detection range up to 7 meters make it a suitable choice for automation projects of varying scales. Its programmable logic controller also allows it to be integrated into emergency stop systems and to control automated processes such as door opening/closing, allowing for greater flexibility and control in production environments.
