Machine Safety - Light Curtains

Light curtains are a type of sensor used to improve safety in automated industrial processes. They are a key component in a system designed to detect potential hazards in the workplace. In particular, light curtains are used to detect the presence of personnel in hazardous areas. The MSF4800B-40-1560 light curtain is an excellent example of a light curtain used to detect personnel presence in the industrial workplace.

Application Field

The MSF4800B-40-1560 light curtain is designed for industrial applications. It is most commonly used in areas where personnel are at risk of injury, such as material handling facilities, machine tools, and industrial robots. It can also be used in hazardous production areas, such as those involving electrically powered equipment. The MSF4800B-40-1560 offers a detection range of up to 36 inches (91 cm), making it ideal for use in narrow areas or tight spaces.

Working Principle

The MSF4800B-40-1560 is a curtain-style light curtain that uses optical fibers to detect the presence of personnel. The light curtain works by emitting a beam of light across the detection area. The beam is detected by a set of photodetectors placed on the opposite side of the area. Depending on the configuration, the photodetectors can be mounted either on the machine frame or on the side of the personnel entry point.

When personnel enter the detection area, the beam is disrupted. This disruption is detected by the photodetectors and triggers the light curtain’s safety shutoff mechanism. This mechanism is designed to shut down any machinery or process that may be in operation and prevent personnel from entering the hazardous area. It is important to note that light curtains can only detect the presence of personnel and not objects or other hazards.

Features and Benefits

The MSF4800B-40-1560 light curtain offers superior performance and reliability in a compact and lightweight design. This light curtain features up to 30 sensing points and can be used with a variety of safety devices, including door switches, emergency stops, and relays. The light curtain is also easy to install and maintain. It can be quickly and easily mounted on any wall or machine frame and its components can be interfaced with other safety devices in the system. Additionally, the light curtain is designed for long-term use, as its components are rated to last up to five years.

The MSF4800B-40-1560 is an excellent choice for protecting personnel in hazardous areas in any industrial setting. Its superior detection range, reliability and easy installation make it a preferred solution for personnel safety worldwide.
