Within the telecommunications industry, it has been
standard practice to use an adapter (male/female) type
of EMI filtered connector as the interface between the
switching system electronics and the premise wiring.
These filtered adapters provide effective containment
of EMI compared to either D-subminiature or 50-position
“ribbon” contact type connectors.
The following several factors have mandated the
development of a new generation of filtered adapters.
Special Requirements
s Higher density wiring
s The need for more contacts, usually
a multiple of 16
s Higher reliability contact geometries
s Bellcore TR-NWT-001089 requirements
s
1000 volts AC withstand for one minute
s
2500 volts spike surge testing
s Improved flammable resistant plastic insulators
Spectrum Control, in response to these unique
requirements of the telecommunication industry,
has developed a new Hi-Density filtered adapter.
Features
s New ceramic technology and filter element
construction to accept higher voltages
s Improved reliability compared to “ribbon”
type connectors
s Integral ground plane and one-piece diecast
housing for the highest level of EMI integrity
s More contacts/wires per square inch of panel space
through Hi-Density arrangements
s 64 contact positions standard, with 78 positions
available by request in any filter combination
