Light curtains are safety devices used to protect personnel where the movement of mechanical components may pose a hazard. The SF4B-A44G(V2) is a safety light curtain particularly suitable for applications where the left and right sides of an end stations share the same power supply. It enables the safety gate to be integrated safely and rapidly within a production line.

The SF4B-A44G(V2) is a modular unit consisting of a receiving unit and a transmitting unit, both designed for mounting in the guard, and connected to a central safety control system. The geometric coverage can be up to five metres, and the built-in E-Stop functions allow for safe shut-down of the process when the light curtain is obstructed. The additional safety covers monitor both sides of the safety gate according to EN954-1, and can be configured differently depending on the application.

The SF4B-A44G(V2) is a four-beam safety light curtain, where the transmitting and receiving units each consist of two active halves, each with an extendable Active Line. This provides redundancy for critical safety coverage, as each line is capable of detecting faults in the other. The Active Lines are connected to the central safety control system and detect any interruption or misalignment in the safety gate. When the operator removes himself from the light curtain, the Active Line is re-established and the safety gate can be activated without resetting the system.

The SF4B-A44G(V2) is capable of withstanding high speed operations, and is ideal for automated production applications. The overlapping area of the light curtain (Transmitter/Receiver pair) is adjustable, providing users with more flexibility for their safety gate design requirements. The IP67 rating ensures that the light curtain is fully protected in areas with high levels of dirt and dust, making it suitable for harsh environments, such as the automotive and machine tool industries. In addition, the SF4B-A44G(V2) can be connected to the Emergency Stop circuit, allowing safety shut-down operations at the push of a button.

The SF4B-A44G(V2) is an advanced light curtain equipped with a variety of features to make it suitable for a wide range of applications. Its safety features provide users with a reliable and fast response, and its adjustable design ensures that safety gate requirements can be achieved. It is a suitable safety solution for many machine safety applications, where personnel need to be protected from the hazards of moving parts.
