SG2 EXTENDED Instruction Manual81.4. Typical applicationsThe safety light curtains of the SG2 series are used in all automation fields where the control andprotection of the access to dangerous areas are necessary.In particular, they are used to stop the moving of mechanical parts in:- Automatic machines;- Machines for packaging, material handling, storing;- Weaving machines, wood working machines,ceramic working machines;- Automatic and semiautomatic assembly lines;- Automatic warehouses.In food industry applications, DATALOGIC AUTOMATION Technical Service has to verify thecompatibility of the material of the safety light curtain housing with any chemical agents usedin the production process.Example 1: Hand protection on moulding machineIn order to protect the light curtain against dust and humidity, the IP69K protective enclosure is used.The aim is to prevent operator hands from being squashed during the final product stacking process.In addition, the solution must not interfere with the manufacturing process. Working premises arecharacterised by a humidity of 85% and a temperature of 25 °C.Moreover, washing with cold high-pressure waterjets is frequent, as well as the use of alkalinedetergents or acids. Cold water rinsing jets (5 - 10 °C) are also used at a pressure of 40 bar.Solution:IP69K protection, made of a PMMA acrylic tube with v4a stainless steel caps, offers an effectivesolution without trapping dirt or contamination. The cap’s O’ring prevents water or dirt from enteringthe tube and at the same time, prevents also internal condensation. The cable connection is protectedand fixed by a PG gland that prevents water or dirt from entering the tube.Advantages:the IP69K protective enclosure (optional) ensures a reliable protection of the light curtains even inextreme environmental conditions. Not only does the IP69K protective enclosure meet hygiene,washing resistance, availability and safety requirements, but also ergonomic and productivityrequirements, as the protected area remains always accessible when the machine is stopped.
