The Schmersal Group (Hawthorne, NY) has developed a new product line for safety light grids and curtains eminently suitable for use in hygiene-sensitive sectors, such as the food industry, pharmaceuticals and meat and milk processing. The new product line SLC/SLG 440 IP69K is resistant to all daily cleaning processes prevalent in such industries. Thanks to a sophisticated, detailed design, this product line achieves the protection rating IP69K and is thus protected against ingress of water during close-range high-pressure and high-temperature spray downs. Other features include:
- Greater availability and a long service life for safety light curtains and grids, also allowing a compact design for encapsulated safety sensors since the protective tubes are a mere 50 mm in diameter.
- Additional functions such as double confirmation, contactor control and integrated beam blanking, which allows moving parts to be conveyed through the protection field without triggering the stop signal.
- A dirt indicator. A visual warning message is displayed if the sensor reception signal becomes weaker. This allows the user to take action before the machine comes to an unscheduled standstill.
