Machine safety - light curtains are a type of industrial safety device and feature an array of light-emitting diodes (LEDs) and photo-receivers integrated into a structure of metal frames and an electrical cabinet. The device emits an array of infrared light beams in a parallel row that forms a virtual screen. The photo-receiver creates an electrical circuit that deactivates when the light beam is disrupted, indicating a human intruder and triggering a request to the machine controls to stop. In this way, light curtains help keep production workers safe by protecting them from the dangerous effects of machinery operation.

The MS4800S-20-1160 is a light curtain specifically designed for industrial safety applications. It has a working range of 18m and is capable of activating safety devices at a maximum distance of 20m. It uses a small footprint of 600mm in length and has an output voltage of 24V DC.

The main application field of the light curtain is in situations where humans need to be protect from hazardous machinery. The device can detect people in its range, signalling the machine to shut down or suspend operations until the person has safely removed themselves from the danger zone. It is often used to protect workers from automated machinery in the production line of manufacturing plants or industrial buildings. It is also used in areas with quick movements of objects or components, as in robotic arms, injection moulding machines, spinning machines, grinders and automated storage and retrieval systems.

The MS4800S-20-1160 is designed to provide safety functions with a high degree of reliability. It has two main circuits that run in parallel and can detect people or objects in the working area. These two parallel circuits are then connected to the safety shutdown circuit, which triggers an automated stop in case of rupture in either of the two circuits. This increases safety reliability as it reduces the risk of a false alarm. In addition, it has a redundant safety cable connection to further increase reliability. The device is also equipped with double-shielding and EMI protection mechanisms to ensure a highly reliable connection to the safety output.

The functioning of the light curtain is based on a set of independent LED emitters and receivers. The LED emitters send modulated light between the devices and the photo receivers detect the light. If any of the elements in the working area interrupts the light beam, a signal is sent to the safety shutdown circuit.

In summary, the MS4800S-20-1160 light curtain is an industrial safety device designed to protect workers from hazardous machinery. It has a working range of 18m and can detect people or objects in its range. It is designed to have a high degree of reliability with two parallel circuits, redundancy safety cable connection, double-shielding and EMI protection mechanisms. Its functioning is based on LED emitters and receivers, sending modulated light beams and detecting their interruption to signal a safety shutdown.
