Product Announcement from Schmersal Inc.
Safety Light Curtains are used for point of operation, danger zone, and perimeter guarding applications but very few are suitable for use outdoors, in marine or wet conditions, or on equipment subject to high temperature and high pressure wash downs.
Schmersal offers light curtains and grids sealed in 60 mm diameter heavy duty, clear plastic sleeves that meet IP69K rating standards. This means that they are dust tight and able to withstand high temperature and high pressure wash downs.
The inner housing has an uninterrupted round profile which provides a rigid body to reduce misalignments from torsion or bending. The outer housing provides smooth surfaces so bacteria and debris cannot collect, making these light curtains suitable for hygiene-sensitive and hygiene-critical applications in the food processing, pharmaceutical, beverage, meat packaging, and medical industries.
The SLC220 Series IP69K rated light curtains are available in 30 or 80 mm resolution, 12 protection heights from 175 mm to 1675 mm, and have a range up to 14 meters. These Type 2 (IEC/EN 61496-1/-2) light curtains meet the safety requirements of CC2 (EN654-1), SIL 2 (IEC/EN 61508) or PLd (EN ISO 13849-1).
The SLC420 Series IP96K rated light curtains are available in 14 or 30 mm resolution, 17 protection heights from 170 mm to 1450 mm, and have a range up to 10 meters. These Type 4 (IEC/EN 61496-1/-2) light curtains meet the safety requirements of CC4 (EN654-1), SIL 3 (IEC/EN 61508) or PLe (EN ISO 13849-1).
