Double Knife Edge™ Door for Industry

Double Knife Edge™ Door for Industry

A New Standard in Knife Edge Door Technology for EMI/RFI Shielded Enclosures.

To improve on the quality and performance of the traditional knife edge door, ETS-Lindgren has introduced a heavy duty Double Knife Edge Door (DKE). Built to last, the DKE is constructed of exceptionally rugged materials with designed-in reinforcements.

The ETS-Lindgren DKE Door is suitable for welded enclosures, modular systems and anechoic and ferrite-lined chambers, where the external mechanism makes it ideal for material application on its interior surface. Its high-strength design makes it ideal for heavy industrial environments or for frequent usage requirements.

Performance

The DKE maintains 120 dB attenuation to 10 GHz, and 100 dB at 26 GHz. When tested in accordance with MIL-STD 285, the DKE design exceeds the test requirements of NSA 65-6 and CID/09/12A.
