Machine Safety - Light Curtains

Light curtains are an essential component in many machinery and manufacturing safety systems. They represent a reliable means of providing personnel protection from hazardous areas while allowing safe operation of machine tools or other process automation applications. The MSF4800S-20-0320 is a light curtain designed for industrial and commercial applications. This article will discuss the application field and working principle of the MSF4800S-20-0320 light curtain.

Application Field of Light Curtains

Light curtains are typically used in applications where personnel protection is required from high-speed or hazardous machinery. These include woodworking, plastics, press systems, and other applications where personnel may be exposed to pinch points, flying debris, or other hazards. The MSF4800S-20-0320 light curtain is suitable for use in a wide variety of industrial, commercial, and residential applications.

The MSF4800S-20-0320 operates in very low ambient light conditions and can be used in applications such as windowless manufacturing rooms or areas with bright security lighting. It is designed to reduce the risk of personnel injury or accidental machine damage due to personnel exposure to hazardous areas. The device can be used to provide a reliable method of personnel detection and machine control in safety systems.

Working Principle of Light Curtains

Light curtains work by emitting and receiving infrared or visible light signals between two points to detect an individual’s presence. When an individual passes through the light curtain, the transmitted signal is disrupted and the curtain triggers an alarm or shuts down the machine. A light curtain typically comprises of two connected frames of LED arrays, one each for transmitter and receiver. Each LED is electronically programmed with certain patterns and these patterns are compared as the signal passes, to detect a person passing the barrier.

The MSF4800S-20-0320 light curtain is designed to meet safety standards and conforms to IEC 60204-1/EN50178/UL508C requirements for personnel detection and protection. The device is capable of detecting an object between 0.25.-1.5m and can be used in applications that require high safety levels. The detector has a reaction time of 20ms and can provide a reliable personnel protection in difficult environmental conditions.

The MSF4800S-20-0320 is a reliable, cost-effective light curtain designed for industrial and commercial applications. It is capable of providing a reliable and safe means of personnel detection and machine control. With its high safety levels, the device can reduce the risk of injuries or accidental machine damage due to personnel exposure to hazardous areas.
