Devices and protective systems must meet special requirements with use in explosion-risk areas. COMPACT EX2 devices with the "non-sparking" ignition protection type and special precautions on the transmitter and receiver housing are available in different models for these applications.
COMPACT EX2 devices are suited for being used up to Ex zone 2 (gases) and Ex zone 22 (flammable, non-conductive dusts). They are especially impressive due to their high interference immunity and availability. In addition to the requirements of machine safety, COMPACT EX2 also satisfies the provisions of ATEX Directive 94/9/EC.
Reinforced connecting front screens ensure that the housing remains sealed with mechanical influences, e.g. an impact or blow of some kind. Metal bushings enclose the cables suitable for explosion-risk areas, which are to be provided by the customer. COMPACT EX2 can be used in industrial applications, however it cannot be used in pits. The device complies as an electrical piece of apparatus of EX device group II, EX category 3.
