D-Subminiature connectors with metal face and EMI/RFI shield Test Results Stray Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) emitted from unshielded cables, connectors, and assemblies can affect the performance of electronic devices within the range of these emissions. The Federal Communications Commission requires EMI/RFI shielding to standards defined in F.C.C. Docket 20780, Part 15 on all newly manufactured equipment. Connectors, cable, and assemblies, if an integral part of this equipment, are within the scope of the F.C.C. decree and must be appropriately shielded. Radiated Emission Comparison Unshielded vs. CW Shielded D-Subminiatures Assemblies Th e CW Solution : CW makes available a choice of two solutions. Select the system that best solves your EMI/RFI emission problem. METAL-FACED D-SUBMINIATURE– A metal face forms the front of your DSubminiature connector and shields high-frequency radiation that eminates principally from the point of external interconnection. These connectors also mate with traditional metal-faced D connectors. EMI/RFI SHIELD–A bright tin-plated metal shield can be added to the METAL-FACED connector to form a complete metal enclosure. Laboratory tests show that our Subminiature D connector enclosed in our assembled shield can reduce strays by up to 80dB. Performance comparison and test results are indicated graphically in the chart at right. When terminated to jacketed-and-shielded flat cable, properly stripped to expose an external conductive surface, the shielding interfaces redundantly with CW’s conductive shield placing the entire assembly at “ground”. CW’s shield can be used on either cable end terminations or in “daisy chain” terminations along the cable. METAL SHIELDS are available to cover 9, 15, 25, and 37 pin or socket Subminiature D connectors. CW’s METAL SHIELDS are designed for easy and rapid assembly to our METAL-FACED Subminiature D-connectors. No supplemental fasteners or assembly tools are required. 22 Radiated Emission @ 3.0 Meters (dBµ V/M) Th e Pr oblem: CW metal-faced D-Submin iatur e con n ector w ith assembled EMI/RFI sh ield Accepts standard flat .050” centers multiconductor cable Metal side plate with teeth to clamp onto cable jacket for extra strain relief Heavy aluminum/mylar foil with external conductive surface for best EMI/RFI attenuation One of two shieldgrounding loops Rugged PVC jacket protects foil from tears and perforations Dimples for positioning D face Extruded and tapped holes accept 4-40 mounting screws • 130 James Way, Southampton, PA 18966 - 3838 • Telephone: (215) 355-7080 • Fax: (215) 355-1088 • www.cwind.com CW metal faced D-Subminiature connectors are ideal for input/output applications and interconnecting electronic equipment.
