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
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 D-SUBMINIATURE–
A metal face forms the front of your D-
Subminiature 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 SHIELD
A 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
shield can reduce strays by up to
80dB. Performance comparison and
test results are indicated graphically in
the chart at right. When terminated to
jacketed-and-shielded flat cable,
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
terminations or in “daisy chain”
terminations along the cable. METAL
SHIELDS are available to cover 9, 15,
25, and 37 pin or socket Subminiature
D connectors. CW’s METAL SHIELDS
are designed for easy and rapid
assembly to our METAL-FACED
Subminiature D-connectors. No
supplemental fasteners or assembly
tools are required.
