In order to reliably secure access points in explosion-hazardous areas, Schmersal has expanded its range of optoelectronic protective devices.
Les barrières et rideaux lumineux de sécurité SLC/SLG440 en version Ex ont été développés pour ces domaines d'application exigeants. Les dispositifs de protection optoélectroniques peuvent être utilisés dans des atmosphères particulièrement explosives de gaz et de poussières des zones 1 / 21 pour sécuriser les postes dangereux.

With the new EX-SLC/SLG440 series, safety barriers and light curtains in Ex version are now available. This allows us to combine the highest safety standards with a quality that no longer needs to be proven.

In many production sectors, the risk of explosion is high, particularly in the chemical industry, refineries or paint shops using flammable coating products. Dust can also lead to an explosion risk in bulk sectors, such as the feed or recycling industry, sawmills or grain companies.
