ATEX Rated Industrial Power Socket and Plugs from Pepperl + Fuchs

There are an untold number of industrial manufacturing industries in existence today, from the manufacture of ceramics, automotive components and the processing of flour, to chemical and fuel production to name just a few. Within all of the industries, some will take place in a relatively safe environment where the chance of a dangerous explosive atmosphere occurring due to build-up of volatile chemicals or particulates in the air is next to nothing, to precisely the opposite.

In the later situation, it stands to reason that you will need to ensure that the machinery, devices and the means to provide them with power, are as safe as possible these areas will ideally be ATEX rated(1) to various degrees. You can never be too safe when it comes to operating machinery in an environment that demands intrinsic safety for obvious reasons. To that end and for a power connectivity solution you can rely on, you need look no further than Pepperl + Fuchs to help you make that safe connection in dangerous environmental atmospheric situations.
