Hi-Density Filtered Adapter
for Telecommunications
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.

Improved flammable resistant plastic insulators
New ceramic technology and filter element
construction to accept higher voltages
Improved reliability compared to “ribbon”
type connectors
Integral ground plane and one-piece diecast
housing for the highest level of EMI integrity
More contacts/wires per square inch of panel space
through Hi-Density arrangements
64 contact positions standard, with 78 positions
available by request in any filter combination
