1011-05-E EMKA EMC EMI Gasketing Electromagnetic Compatibility
Gasketing does double duty, it solves the main EMI problem: leakage around the door, and also provides a water and dust barrier (not to NEMA 4).  This gasketing is relatively easy to install, reducing both total cost and the possibility of error.
EMI gasket is also available in 4 rectangular sections: ½” x 1/8″, ½” x ¼”, 8 x 5mm and 15 x 4mm.  These are constructed from the same conductive fabric over polyurethane foam. All sections have a pressure sensitive adhesive on one side.
