Light curtains are widely used in many industrial applications for worker safety, such as manufacturing, assembly, and machine tending. The MS4800A-14-0920-10X-10R-RMX is a light curtain manufactured by ABB, one of the leading suppliers of safety products in the industry. It is designed to provide barrier-style protection for workers in high-risk areas. This article will discuss the application fields and working principles of the MS4800A.

Application Field

The MS4800A light curtain is designed for use in a wide range of industrial applications. It is particularly suited for safety-critical applications such as machine tending, assembly, and robotic welding. It is made from a corrosion-resistant aluminum housing and is suitable for use in wet and dirty environments. It has a 10m wide detection area, with a resolution of up to 10 targets, and can be linked together to create larger protection zones. It is also certified to EN 61496-1 and the standards set out by the International Electrotechnical Commission (IEC).

The MS4800A is also suitable for use in hazardous work environments, such as those involving explosive atmospheres, as it is ATEX-certified for use in such areas. It is also certified for use in SIL3 compliant applications.

Working Principle

The working principle of the MS4800A is based on two imaging sensors that scan each other’s fields of view. The sensors are arranged in a line that stretches across the protected working area, and they continuously monitor the space between them. When an object intersects the line of sight of the sensors, an interruption signal is sent to the control unit, triggering an alarm or activating a machine safety system.

The MS4800A has two selectable detection modes: “window” mode and “zone” mode. In the window mode, an interruption is only triggered when an object entirely intersects the field of view of both sensors. In the zone mode, an interruption is triggered when an object enters or leaves the field of view of the sensors, no matter how small the object is. This second mode is ideal for applications that require a high level of sensitivity, such as robotic welding.

The MS4800A is also equipped with a range of other features, such as adjustable detection thresholds. This allows users to adjust the light curtain’s sensitivity depending on the application and the type of objects that may enter the protected area. The light curtain also has a built-in diagnostic system, which alerts users to any potential issues, such as a defective optical fiber, and can reset the system if necessary.

Overall, the MS4800A is a reliable and highly adaptable light curtain that provides a robust safety barrier for industrial applications. Its wide working area, adjustable detection thresholds and built-in diagnostic system make it an excellent choice for safety-critical applications.
