Shielded Cabinets Meet MIL-STD-461D

Based on Optima’s M-series, its latest shielded cabinets are fully tested to MIL-STD-461D specs for EMC. They employ a steel or aluminum frame and EMC features include shielded door handles, wrap-foam gasketing around the door with conductive adhesives, EMI filters, copper gasket fingers, and steel-mesh gasket strips. Custom EMC and shielding topologies are also available, i.e., tin-plating or other conductive metal surfaces. Using cost-effective materials, a minimum electric field attenuation of 60 dB of shielding effectiveness from 100 kHz to 1 GHz decreasing to a minimum of 46 dB at 10 GHz is achieved. The cabinets also feature reinforced corner members, cross-bracing, and stiffeners to handle rugged applications and have also passed MIL-STD-901D and MIL-STD-810F for shock and vibration.
