Light curtains are a kind of highly sensitive safety device and an important part of the safety control system, which can be used to sense human body, object movement, and can effectively protect personal and machine safety. SF-4B-A8G (V2) light curtain is a safety protection device which can be widely used in automated operations and precise machinery production to provide a safe and reliable working environment.

Application Field

SF4B-A8G (V2) can be applied to all kinds of hazardous protection fields such as peripheral boundary protection, walkway protection, conveyor protection and palletizer protection. Especially for difficult to install light curtains such as hot or cold environments and narrow channel installation, SF4B-A8G (V2) is an ideal solution.

The SF4B-A8G (V2) light curtain can be used in various applications such as, metal stamping presses, transfer lines, robotic and assembly cells, conveyors, warehouses, and general conveyance systems. With its IP67 protection rating, it can also be used as a highly reliable protective device in more demanding areas such as woodworking centers, machine tools, foundries and production lines.

Working Principle

SF4B-A8G (V2) light curtain uses an infrared filtering system to transmit and receive invisible beams of light. It consists of a transmitting head and a receiving head. The transmitting head continuously transmits infrared beams, and the receiving head receives the infrared beams to form a sensing beam. When the sensing beam is blocked, the receiving head sends a signal to the programmable controller and the controller sends a contactor switch signal to the backup circuit to execute a trip.

The SF4B-A8G (V2) features a physical protection height of up to 8 m and a resolution of 90mm, providing a high detection accuracy, fast response times, and high levels of EMC protection. It also features an adjustable sensitivity threshold and a selectable function to turn off select or all detection cells to prevent false trips that could stop the operation of the device. Additional features include a leakage current monitoring function to detect signal leakage and an error log function for improved system operation and maintenance.

The dia-connectivity of safety systems also allows SF4B-A8G (V2) light curtain to be connected quickly and easily. The RFID-based sensor module enables remote wireless setup of the light curtain and logging of operational parameters. The module also supports real time monitoring and data acquisition, allowing safety personnel to monitor the overall safety system performance.

Conclusion

The SF4B-A8G (V2) is a reliable safety device which provides a safe working environment as it safeguards personnel and equipment from potentially hazardous conditions. Its high performance detection system, adjustable sensitivity threshold and error log function, make it an ideal solution for industries that require a high level of safety. Additionally, its RFID-based sensor module provides real-time monitoring and data acquisition, enabling efficient system performance monitoring.
