Machine safety is an important consideration in the design of many types of machinery, and light curtains are a common tool employed to help achieve that safety.The MS4800B-20-0320-R is an example of such a light curtain, designed to provide effective protection for personnel and machinery from possible collisions.

Light curtains used in machine safety are typically mounted along the perimeter of a hazardous area, creating an effective barrier designed to detect the presence of people or objects that could create a potential safety hazard. The MS4800B-20-0320-R is designed to be mounted along the outside of the area to be protected or along the inside. In either configuration, it detects objects passing through its field of view, and it can be used to create a single corridor, as part of a two-part light curtain system, or a full barrier system.

The MS4800B-20-0320-R features a sensing field that consists of twenty reverse-biased optoelectronic sensors, spaced 20mm apart, mounted along a length of cable. Each sensor consists of an infrared LED and a phototransistor. When light is emitted from the LED, it is detected by the phototransistor if something breaks the beam and interrupts its path. This triggers an output signal that can be used to automatically initiate an emergency stop function, preventing potentially damaging or dangerous events.

The MS4800B-20-0320-R is designed to be highly reliable and resilient to harsh environmental conditions, including variable temperatures, humidity and dust. The cable features a PVC sheath that provides protection from dust and other contaminants, while the LED and phototransistor are coated with UV stable oil to resist damage from exposure to sunlight. Furthermore, the sensors feature a stainless steel shield to protect against corrosive atmospheres.

The MS4800B-20-0320-R is a great example of a light curtain used in machine safety applications. The curved cable design and optional accessories make it suitable for a range of different applications, including hazardous areas, areas with limited access, and robotic applications. The sensing field is designed to be highly reliable and resilient to environmental conditions, and is capable of detecting the presence of people or objects that could create a potential safety hazard. By implementing such light curtains, manufacturers can help ensure that their machines are safe to operate and workers remain free from potential harm.
