Stainless Steel (EJBX)

The EJBX series features 42 sizes of Ex d IIB+H2 and Ex tb certified enclosures made from stainless steel. EJBX enclosures are particularly well suited to withstand even the harshest environments without the use of any further surface treatment. The properties of stainless steel also match the requirements for installation on offshore oil rigs or petrochemical plants where light alloy is not permitted.

A comprehensive choice of certified operator elements such as switches and pushbuttons as well as monitoring devices allow the tailor-made design of control stations. In conjunction with non-Ex devices specified by the customer, from terminals to transformers or PLCs, which will be integrated into the enclosures, the Pepperl+Fuchs project engineers will design elaborate control and distribution panels as efficient solutions to any requirements.

Contact your Pepperl+Fuchs representative for a customized configuration of your EJB/X control solution, and get advice on all available options for built-in instrumentation.
