When using a conductive enclosure, the EMI/RFI screening achieved can be significantly impaired with the application of a non-conductive sealing mechanism. DEM Manufacturing has designed an EMI/RFI seal which maintains conductivity between the lid and box, and is essential to eliminate high frequency radiated emissions. This therefore allows EMI and RFI screening properties to be unaffected, whilst maintaining a watertight seal of up to 1m for 30 minutes (IP67), and depths of up to 5 metres for 1 hour (IP68). This means the enclosure is ideal for use in high humidity, underwater applications and applications subjected to heavy spray.
