Hi-Density Filtered Adapterfor TelecommunicationsFiltered ConnectorsWithin the telecommunications industry, it has beenstandard practice to use an adapter (male/female) typeof EMI filtered connector as the interface between theswitching system electronics and the premise wiring.These filtered adapters provide effective containmentof EMI compared to either D-subminiature or 50-position“ribbon” contact type connectors.The following several factors have mandated thedevelopment of a new generation of filtered adapters.Special Requirements■ Higher density wiring■ The need for more contacts, usuallya multiple of 16■ Higher reliability contact geometries■ Bellcore TR-NWT-001089 requirements■■1000 volts AC withstand for one minute2500 volts spike surge testing■ Improved flammable resistant plastic insulatorsSpectrum Control, in response to these uniquerequirements of the telecommunication industry,has developed a new Hi-Density filtered adapter.Features■ New ceramic technology and filter elementconstruction to accept higher voltages■ Improved reliability compared to “ribbon”type connectors■ Integral ground plane and one-piece diecasthousing for the highest level of EMI integrity■ More contacts/wires per square inch of panel spacethrough Hi-Density arrangements■ 64 contact positions standard, with 78 positionsavailable by request in any filter combinationMechanical SpecificationsShell . . . . . . . . . . . .
