A CM ES or CM PE sealing module consists of two halves, and has removable layers and a center core. Thanks to the multidiameter technology, one single module can seal a cable or pipe of several different diameters simply by peeling layers away from the module halves until a perfect fit is achieved. CM ES and PE modules are used in frames of product line C, fitted around cables, as spare capacity or as compensation. The modules have a depth of 40 mm and accommodate a diameter range from 3.5 to 32.5 millimetres.
The CM ES and CM PE modules have a conductive foil which establishes a full 360 degrees low transfer impedance contact with each individual cable screen, thereby leading the induced disturbances via the frame to ground. In addition the ES version has a conductive rubber screen, which effectively shields against electromagnetic fields.
