Light curtains are an important part of advanced machinery safety systems and have the potential to provide users with increased safety and improved productivity. The SF4B-H28 (V2) is a light curtain from a leading manufacturer of industrial safety products, and is a powerful device for safeguarding personnel in hazardous industrial environments. This article explores the applications and working principles of the SF4B-H28 (V2) light curtain.

Applications

The SF4B-H28 (V2) is used extensively in industrial settings for protection of personnel and machines. It can be used to create a safety barrier around any machine or equipment, prohibiting access to hazardous areas, and can be activated or deactivated according to system requirements. The SF4B-H28 (V2) is highly adaptable, enabling it to be installed quickly and easily into existing systems, and providing operators with customisable control options including selector switches, solenoid valves and timers.

The light curtain is also suitable for safeguarding personnel in a variety of industries, including power plants, manufacturing facilities, clean rooms and automated production lines. It can be used in conjunction with other safety equipment such as emergency stop buttons, safety relays and sensors to further increase operator safety. With its integrated alarm, the SF4B-H28 (V2) can be used to detect unsafe conditions in the working environment, and alert personnel if the light curtain is breached. The device also features adjustable sensitivity, enabling it to exclude plants and background reflections, and ensuring reliable detection in difficult environments.

Working Principle

The SF4B-H28 (V2) is designed to use optical detection technology which is based on the concept of Diffraktion. A beam is projected from a transmitter and crosses a gap of up to 20m, after which it is detected by the receiver. When an object breaks the beam, it is detected and the device immediately sends an alarm signal. This is then used to deactivate the machine or equipment, or trigger other safety systems to react.

To ensure reliable detection over distances, the SF4B-H28 (V2) is designed to use infrared radiation. It contains an array of light emitting LEDs and detectors, which detect the light that passes through the gap and is reflected back to the detector. The device is also equipped with adjustable reflectors and lenses, which can be used to adjust the angle and distance of the light beam, allowing for flexible installation and for users to adjust the sensitivity of the system.

The SF4B-H28 (V2) is further supported by an advanced signal processing algorithm, which ensures its far-reaching detection capabilities. Additionally, the device is capable of detecting moving objects over long distances at speeds up to 50Km/h. This enables the SF4B-H28 (V2) to be used in applications such as automated production lines, where fast-moving objects need to be detected in order to ensure the safety of personnel and machinery.

Conclusion

The SF4B-H28 (V2) light curtain is an advanced safety device which is designed to ensure the safety of personnel and machinery in hazardous industrial conditions. It uses advanced optical detection and signal processing technologies to ensure reliable detection over distances of up to 20m. Additionally, the SF4B-H28 (V2) is highly adaptable, enabling it to be quickly and easily integrated into custom safety systems.
