D/G Photoelectric Switches for Explosive Areas The Category D/G photoelectric switches from SICK are equipped with a metal housing. This housing meets the demanding requirements of the Standard and therefore offers a ready-to-fit solution in respect of the standard. Product range: W8-Ex: Compact dimensions, accurate background suppression, insensitive to optical interference, sensor E range up to,000 mm and up to m as a photoelectric reflex Ex series modules are designed for explosive areas in ignition switch, W-Ex: Complete range of protection Type n according to photoelectric switches: scan- EN 00. Hence, they conform ning distance up to,00 mm, to Categories G and D, based range up to m on a reflector on the new 9/9/EC (ATEX) and m as a through-beam Directive, and can be used in the photoelectric switch, areas Zone (gas) and Zone (non-conductive dust). WTREx: Economical solution for scanning distances up to 900 mm, In addition to limit values for WL-Ex: The powerful temperature, performance or UV photoelectric switch with a resistance, the Standard stipula- range of up to m. tes a mechanical strength which cannot be achieved with standard sensors. 08 SENSICK CATALOGUE
