Suitable for gaseous and dusty atmospheres of zones 1 / 21 and ignition protection type op is : the new SLC / SLG440 series of safety light curtains / barriers in Ex design .
The Schmersal Group has expanded its range of optoelectronic protective devices with a series of safety light curtains / grids in Ex design . The new EX-SLC / SLG440 series is designed in the ignition protection types EX d ( gas atmospheres ), EX t ( dust atmospheres ) and EX op is ( optical radiation ) and is thus especially suitable for access protection of potentially explosive areas in industrial production - namely for zones 1 and 21 .
There is an elevated risk of explosion in many areas of manufacturing , such as in the chemicals industry , in refineries or paint shops where flammable coatings are being used . In industries that process bulk materials , such as in the animal feed or recycling industries , as well as in sawmills and plants that process cereals and grains , there is a risk of

When one or more of the beams is interrupted , hazardous movements are brought to a halt .
The series is ATEX certified and further certification – IECEx , INMETRO and CCC Ex – are due to follow . The sensor system is accommodated in a protective enclosure made from non-breakable glass .
Ex-SLC440 safety light curtains for finger , hand and body detection are available in versions with a resolution of 14 and 30 mm as well as ranges of between 0.3 and 20 m . Ex-SLG440 safety light curtains are suitable for access control to hazardous areas .
The waterproof and dustproof devices achieve IP66 and IP67 protection class and also have the capability to be used outside .
