F3SG-4RA0270-30

Light curtains are a device used to prevent physical harm to personnel in hazardous machinery operations. The F3SG series of light curtains from Omron is a popular model designed to meet safety standards while providing users with a reliable and low-maintenance safety solution. The F3SG-4RA0270-30 model is a 4-beam, finger-level safety light curtain.

Application Field and Working Principle

The F3SG-4RA0270-30 is specifically designed for areas where personnel are prone to enter the functioning area of potentially hazardous operations. It is most commonly used for the prevention of machine injuries and accidents, such as those due to careless work or lack of understanding of the machine’s movements. The device is designed to detect and protect personnel from entering the hazardous area of the machine.

The working principle of a light curtain is as follows: Light-emitting diodes (LEDs) positioned in two frames transmit invisible infrared light beams in all directions. When an object interrupts the light beams, the receiver detects the change and sends a signal to the safety controller. The safety controller then sends an output signal that stops the machine movement or operation, ensuring personnel safety.

Performance

The F3SG-4RA0270-30 has a resolution of 20mm, which corresponds to a resolution of 0.1mm when divided into “S” type channels. This resolution is more than sufficient for most applications where personnel safety is concerned. The light curtain has a protective height of 270mm, which provides personnel with adequate protection from hazardous operations. The device has a scanning rate of 25ms, acheiving a maximum safety distance of 12.5mm.

The device is IP67 rated and can be installed in even harsh environments. It is also equipped with reinforced insulation, dual LED circuit, and enhanced surge voltage protection which prevents false operation due to noise interference from other devices. Its self-monitoring feature (SOM) also increases the reliability of the safety curtain by alarming users of any malfunctioning.

Conclusion

The F3SG-4RA0270-30 is an effective and reliable safety light curtain for hazardous operations. Its advanced features and protective height provide users with the assurance that personnel safety is a top priority. The user-friendliness and low-maintenance design of the device make it a suitable solution for anyindustrial environment.
