D-Subminiature connectors with metal face and EMI/RFI shield Th e Pr oblem: 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. Test Results Radiated Emission Comparison Unshielded vs. CW Shielded D-Subminiatures Assemblies Radiated Emission Meters dBµ V/M 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 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 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 CW metal-faced D-Submin iatur e con n ector w ith assembled EMI/RFI sh ield shield can reduce strays by up to 80dB. Performance comparison and test results are indicated graphically in Accepts standard flat centers multi- Metal side plate with teeth to clamp onto the chart at right. When terminated to conductor cable cable jacket for extra jacketed-and-shielded flat cable, strain relief 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 Heavy aluminum/mylar foil with external conductive surface for best EMI/RFI attenuation One of two shield- terminations or in “daisy chain” grounding loops terminations along the cable. METAL Rugged PVC SHIELDS are available to cover 9, 15, 25, and 37 pin or socket Subminiature D connectors. CW’s METAL SHIELDS jacket protects foil from tears and perforations are designed for easy and rapid assembly to our METAL-FACED Dimples for positioning Subminiature D-connectors. No D face supplemental fasteners or assembly tools are required.
