Light curtains are safety devices that transmit invisible beams of infrared light that sense the obstruction of the beam when it is interrupted. SF4B-A20(V2) light curtains belong to the type of category 4 light curtains, the highest category of safety light curtains in terms of performance. The SF4B-A20(V2) offers an array of features that make it an ideal solution for a range of industrial applications.

The SF4B-A20(V2) light curtain is a reliable safety device that provides quick detection of an opaque object, which is essential to any manufacturing process. It has two transmission and reception modes, the first being selective blind speed monitoring (Sirs2) which is used to detect excessive speed or to monitor flexible materials. The second mode is continuous monitoring (Xirs1), which is used to monitor fixed products in repetitive processes.

It has a resolution of 20mm / 0.78in and a protection height of 2.0m / 6.6ft. It is suitable for a wide range of applications from medical, pharmaceutical, automotive and food processing to machine tool protection, woodworking and general factory automation. It is designed with built-in error detection and alarm giving high assurance of reliability.

The SF4B-A20(V2) is certified with EN954-1, Category 4 and meets the requirements of IEC 61496-1 and IEC 61496-2 including SIL 3 and PL e. Despite its high safety level, it offers remarkable flexibility, compatibility and configurability. It is based on fiber optic technology, so it can be mounted away from a machine’s moving parts without sacrificing safety performance.

The SF4B-A20(V2) is easy to install and requires little maintenance. The curtains can be installed with minimal effort and the built-in installation test ensures the safety of the machines. It is an ideal solution for a wide range of applications that require a high level of safety. Its innovative design and reliable performance make it the perfect solution for any industrial environment.

The SF4B-A20(V2) light curtain is equipped with advanced features such as a fast response time, high signal stability, adjustable beam pitch, automatic line diagnostics, adaptive waveform analysis and active sensing. The device uses a combination of an electronics board and a series of photoelectric arrows to create a flexible detection zone that can detect an object regardless of its size or shape. It also has an adjustable motion speed set so that the machine is able to detect the motion speed of the object and stop in time if it is travelling too fast.

The SF4B-A20(V2) provides a high level of protection and reliability. It is a perfect solution for any industrial environment where safety is of paramount importance. It is a simple device that offers a reliable performance, high levels of flexibility and is easy to install and maintain.
