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.

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.

METAL-FACED connector to form a
complete metal enclosure. Laboratory tests show that our Subminiature D connector enclosed in our assembled
