MSF4800A-20-1280

Machine Safety - Light Curtains play an essential role in protecting people in a variety of environments. MSF4800A-20-1280 is a light curtain that is designed to help ensure the safety of operators and personnel by maintaining required clearances between moving and stationary machine components. The light curtain is a combination of sensing and emitting elements, operating with light beams that are sent from the transmitter to the receiver. When an operator or object breaks the light beam a switch is operated instantly, interrupting power to the hazardous area and stopping the machine.

Features

The MSF4800A-20-1280 is an advanced light curtain that features a number of useful features, including detection of objects down to 0.18 inches in size, adjustable height from 80 to 140 inches, adjustable beam intervals from 0.04 to 5 inches, adjustable scanning range from 80 to 140 inches, and multiple mounting configurations. Additionally, it is suitable for both indoor and outdoor applications, and has NEMA4X IP66 protection against dust, water, and other environmental contaminants. The light curtain also features automatic start-up and shut-down functions, a safety circuit status indicator, and a solid-state self-test to monitor operation.

Installation and Security

Installation of a light curtain is simple and does not require any special tools. The MSF4800A-20-1280 is designed to be mounted quickly and securely, with a minimum of fuss. The unit has adjustable mounting brackets so that it can be installed in a variety of locations, and the height can be adjusted to fit the desired application. Additionally, the light curtain can be attached to most surfaces with just a few screws and the power requirement is just 24VAC.The MSF4800A-20-1280 also offers a high level of security, with its multiple layers of protective relays to prevent unauthorized access, and its basic status indicator to show the system\'s status. Additionally, the light curtain features an integrated Q System Check to monitor the operation of the system, and it also features a built-in homing module that allows personnel to quickly reset the system in case of an emergency.

Working Principle

The MSF4800A-20-1280 Light Curtain operates on the same principle as other safety measures: a beam of infrared light is emitted from the transmitter, and if the receiver does not detect the presence of this light, then it is assumed that an operator or object has penetrated the zone of protection. As soon as the light is blocked, the receiver instantly triggers the safety switch, which interrupts power to the hazardous area and stops the machine.In practical applications, the light curtain is connected to a safety circuit, which includes a safety relay, switch, and indicator. The switch is normally closed, allowing power to flow through the circuit and to the hazardous area. When the light beam is blocked, the safety relay is immediately activated and it drives the switch open, interrupting power to the hazardous area and stopping the machine. The indicator then signals that the safety circuit is open.

Application Field

Light curtains such as the MSF4800A-20-1280 are designed for use in many different applications, including industrial processing and manufacturing, food processing, material handling, robotics, and automotive assembly lines.Furthermore, the light curtain can be used to protect personnel from hazardous areas, as well as from machines and objects, in areas where personnel could be injured or extinguished due to contact with dangerous moving parts. This includes installations in warehouse storage, delivery bays, mills, sawmills, factories, airports, loading docks, traversing processes, packaging lines, and more.

Conclusion

The MSF4800A-20-1280 is a highly reliable and efficient light curtain that can be used to protect personnel and equipment in a variety of hazardous working environments. Its simple installation, adjustable mounting brackets, and power requirement of just 24VAC, make it an ideal choice for applications where safety and compliance are of paramount importance. Additionally, the light curtain\'s built-in Q-System Check and homing module ensure that personnel have access to a reliable and secure safety circuit.
