Machine safety can be made even more secure and efficient with the help of light curtains such as the SF4B-F79-01(V2). Light curtains are designed to provide reliable protection against potentially hazardous machine movement or processes.

In general, these light curtains form an invisible, high-resolution area of protection that comprises a series of infrared LED emitter and receiver units working together. When something interrupts the sensor beam, such as a part of a person, the emitted and reflected beams are mismatched, and the protective system is triggered accordingly.

One of the most widely used applications for these light curtains is when they are used in conjunction with safety fencing. This means that the light curtain provides an even higher level of protection for personnel performing tasks around hazardous machinery. In this scenario, if an object or person enters the beam, the machine will immediately shut down, preventing potentially deadly accidents.

The SF4B-F79-01(V2) light curtain is a four-beam type offering coverage for a wide variety of applications. It is a Type 4 light curtain type according to IEC 61496-1:2008, making it suitable for use in applications where safety risks are high. Its design also means that it can be used in highly complex environments, where several light curtains may be connected in series.

In terms of the working principle, the SF4B-F79-01(V2) features a quad-beam design, with each beam providing an equal distance of protection in front of the light curtain itself. Each beam is interlocked with the other four so that if a beam is interrupted, the remaining beams will be blocked until the interruption has been cleared. This means that if an object enters the light curtain area while two or three of the beams are blocked, the light curtain will continue to protect the area.

In order to provide reliable protection, this light curtain features a fail-safe design that will stop hazardous motion immediately upon detection of an interruption. This design also ensures that the protection of personnel is maximised, as the light curtain will stop the machines regardless of the start-up speed. Furthermore, the light curtain is designed to detect objects as small as 3 mm in size, meaning that even the smallest of objects will be detected.

The SF4B-F79-01(V2) is a highly advanced light curtain that offers maximum protection and safety for hazardous applications. Its quad-beam design ensures that it provides reliability and high-speed protection, while its fail-safe design and small object detection offers maximum protection for personnel in the vicinity.
