PMA Ex-System

Please note:

Due to changes in the standards called up by the ATEX directive PMA has developed a new product line for hazardous applications. The former PMA Ex system no longer complies with all the current standards and will be phased out after a transition Phase.
The products should not be designed in to new applications.


The newly developed product line which is both ATEX and IECEx approved is being marketed together with a much broader portfolio of cable protection products under the brand name Kopex-EX

For existing PMA-EX applications please contact your local distribution partner

For more information, you can also contact PMA directly
