Apw president systems limited manufactures card frames [sub-racks], 19" floor standing cabinets, table racks, instrument cases, and a whole host of accessories for each of these product groups.
The electromagnetically compatible [emc] cabinet family from apw president is a tough enclosure system. These cabinets provide a high level of rfi shielding so as to protect sensitive electronic equipment housed inside them against interference from external electromagnetic radiation.
These emc cabinets have been carefully engineered to provide between 30 - 55 db of signal attenuation in the frequency range of 1 mhz - 1000 mhz. The rfi gaskets used are combination elastomer gaskets, which provide not just radiation sealing, but environmental sealing as well.
