TNC Connectors
TNC series connectors are general-purpose,
miniature connectors, with a frequency range
of DC–11 GHz and 50Ωimpedance, designed to
MIL-PRF-39012 requirements.
Their threaded interface provides secure mating
and unmating, and prevents accidental discon-
nection from pulling forces on the cable.
Automatic TNC cable connectors are available
with nine standard cable attachment types for
flexible and semi-rigid cable:
• Standard and Improved Wedge-Lock; our
patented, quick assembly method for flexible
cable incorporating a captive center contact,
only three parts to handle, and requiring no
special tools.
• V-Groove clamping with captive or noncaptive
contacts for flexible cable, requiring no special
tools for assembly.
• Econo-Crimp types with captive or noncaptive
contacts for flexible cable, providing small size,
light weight, and rapid assembly using
standard, commercially-available crimp tools.
• X-Crimp with captive contacts for flexible
cable, providing rugged, high-strength cable
attachment and quick assembly.
• Wedge-Eze for flexible cable is our unique
system featuring quick assembly, color coding
by cable size, and field replaceability. Rapidly
assembled with hand or automated tooling.
• Solder-Clamp assembly for semi-rigid cable
requires no special tools and allows for re-
orientation of the connector after assembly to
easily conform to system layout. Collet type
clamping for solderless attachment of semi-
rigid cable is also available.

details on all cable attachment types.
Many of our TNC connectors are qualified to
MIL-PRF-39012, and adapters to MIL-PRF-55339.
Some of our M39012 QPL cable connectors are
available with your choice of Wedge-Lock,
V-Groove, or Econo-Crimp cable attachment.
Information on our TNC QPL connectors and
adapters is available on our website.
The versatility of TNC series of RF connectors is
enhanced by Automatic’s ability to provide a
wide range of alternate constructions and
configurations to meet virtually any system
requirements. Contact us with your requirements
for custom configurations, such as:
• Polarized mating interfaces with reversed
contacts and insulators to prevent accidental
mating of incompatible circuits. (see illustration
at left).
• Coupling nuts can be provided with lockwire
holes for safety wiring after mating in high-
vibration applications. Hex coupling nuts are
also available.
• Twinaxial and Triaxial versions of all types are
available to maximize shielding in sensitive
systems.
• 75 ohm impedance versions are available in all
TNC configurations.
• TNC connectors with aluminum bodies can
provide significant weight savings.
Notes:
The standard TNC connectors in this section have
silver-plated bodies and gold-plated center
contacts. All are available with other platings
if required.
Drawings in this section are approximately actual
