Machine Safety – Light Curtains

Light curtains, also called photoelectric beams, are a type of safety devices that use infrared sensor technology to protect against potential injury in moving production lines. For this purpose, they are widely used in the industrial environment and manufactured in compliance with the safety regulations and standards for use in the hazardous areas of the workplace.

The MS4800S-30-0360-10X-10R-RM2AP light curtains are one of the most popular models in the market and are suitable for use in hazardous environments such as welding, grinding, and assembly lines where access is restricted by a guardrail-type fence system. The device comes with all the necessary components including power supply, guardrail, photoelectric receiver, and emitter.

Application Field

The MS4800S-30-0360-10X-10R-RM2AP can be used in a variety of applications, including hazardous areas where personnel are exposed to potential hazards such as flying debris, liquid splashes, and other hazards associated with operation of moving machinery. Other applications include semiconductor processing, the automotive industry, packaging lines, forestry, and the military field.

The light curtain has a range of 10 meters and can detect any breakage in the guardrail or safety gate. It is equipped with an adjustable sensing distance and triggering range to ensure that even small objects will be detected.

Working Principle

The safety curtain device is composed of a light emitter and receiver modules. The transmitter emits an infrared beam that crosses between the emitter and receiver. The receiver detects any interruption of the beam by an opaque object, such as an arm or tool, and triggers an alarm indicating a potential safety hazard.

The MS4800S-30-0360-10X-10R-RM2AP can be pre-programmed to operate in a range of different modes, such as detection, reaction and test modes. Detection mode is for continuously monitoring a guarded area. When an interruption in the light beam is detected, the alarm is triggered and the machine is immediately shut down. In reaction mode, the alarm is triggered when an interruption in the beam is detected. In test mode, the device can be used for testing the functionality of the sensors and setting the safety parameters.

The MS4800S-30-0360-10X-10R-RM2AP is equipped with several additional features to ensure reliability and safety. The most important of these features is the self-testing feature that will continuously check the proper functioning of the device. It can be programmed to send an alert signal when the device needs maintenance or repair. The device also has redundancy with two individually identifiable sensors in parallel operation.

Conclusion

Light curtains, such as the MS4800S-30-0360-10X-10R-RM2AP, are extremely important in providing safety for personnel working in hazardous environments. They offer a reliable and foolproof way to detect intrusions with infrared beams that are capable of detecting even small objects. The device can be programmed to operate in a range of different modes, including detection, reaction and test modes, and is equipped with a number of additional features for reliability and safety.
