Platform for the food and beverage industry
Especially for hygiene-sensitive sectors such as the food industry, milk and meat processing as well as pharmaceuticals, the Schmersal Group has developed a new line of light barriers.
The new SLC / SLG 440 IP69K product line withstands all common cleaning processes found in these industries. Thanks to an advanced, detailed design, this product line achieves IP69K protection class and is therefore protected against water ingress during direct high-pressure and steam cleaning. This means that the seals of these light curtains meet very strict requirements and can withstand frequent cleaning with water, alkaline solutions, foam, hot steam or high-pressure jets. In addition, the new light curtain series is designed according to the requirements of "Hygienic Design".
The SLC / SLG 440 IP69K end caps are made of stainless steel (V4A) as are the cable entry and mounting parts. The transparent protective tubes are made of polycarbonate (PC) and not only offer high resistance to cleaning agents but also withstand strong mechanical loads. If the spray lances accidentally hit the housing of the SLC / SLG 440 IP69K during high-pressure cleaning in food production or if a transport collides with the housing, the safety and protection function continues to work thanks to the robust protective tubes.
The material thus guarantees greater availability and a long service life for safety light curtains, which also allows a compact design for built-in safety sensors because the protective tubes are only 50 mm in diameter. The independent testing laboratory Ecolab also tested and confirmed the material resistance of these components.
Moreover, this light curtain series is equipped with additional functions, such as feedback, double reset and blanking, which allow moving parts to be transported through the safety field without activating the stop signal. Another practical feature is the contamination indicator. An optical warning becomes visible when the receiving signal from the sensor weakens. This allows the operator to take action before the machine comes to an unintended stop.
