Specifications and dimensions subject to change
Cannon’s precision SMA connectors feature the
MIL-C -39012 Series SMA interface and envelope
configuration. They can be mated with all
connectors meeting the MIL specification
dimensions. Designed for use with a variety of
subminiature coaxial cables, superior results are
obtained from DC to 18 GHz when used with semi-
rigid cables and from DC to 12.4 GHz with flexible
cable.These connectors are manufactured with
beryllium copper bodies which are gold plated or
stainless steel bodies which can be supplied with
either a gold plated or passivated finish.
Cannon also offers a range of commercial SMA
brass bodied connectors. For further details, please
see page 13.
