Machine Safety - Light Curtains

Light curtains are safety devices used for various applications where physical barriers are not feasible. They consist of two rows of many light beams on a grid, and if any one of the beams is broken, it will signal that a person or object is in the way and trigger an alarm or even shut down the equipment.

The MS4800S-30-0880-50X-50R is one such light curtain, designed for machine guarding applications. It is a very durable light curtain with a mechanical actuation rate (MAR) up to 50 million cycles. It has a sensing distance of 880mm and a beam density of 50 chains per meter.

The working principle for the MS4800S-30-0880-50X-50R is simple. Each beam within the light curtain is composed of an emitter and a receiver. When the two are in line with each other, the beam is said to be “on” and when the two are disrupted, the beam is said to be “off”. The light curtain looks for any interruption in any of the beams. If any one of the beam is broken, it will send a signal to the controller, alerting it to the presence of an obstruction. The controller then takes appropriate action, which could be an alarm, a shutdown, or even an automatic reset.

The MS4800S-30-0880-50X-50R light curtain is used in many applications where physical barriers cannot be used, such as automated palletizers, robotics, and automated machinery or equipment. For example, the light curtain can be used to protect workers from hazardous parts, such as moving blades, as well as to monitor the movement of pallets on conveyors. Its long range of 880mm makes it ideal for large machinery, where it can detect an obstruction from a distance and take the necessary measures to prevent injuries or property damage.

Light curtains are a great way to improve safety and security in any industrial application where physical barriers are impractical or impossible to use. The MS4800S-30-0880-50X-50R light curtain is a highly reliable and durable solution that can help to protect workers and equipment from potential harm.
