I
TT’s wide range of Cannon Type 43 / SMZ connectors are exten-
sively used in 75 ohm communication systems and have become
the recognized standard in telecommunications in many parts of the
world.
D
esigned around the requirements of BS9210 F0022 and draft
specifications CECC 122 300, these connectors are designed for
field installation and feature the ‘Posi-Lock’ latch to prevent acci-
dental disconnection.
A special feature of the Cannon Type 43 / SMZ range is the QT
(Quick Termination) technology for cable connectors. Designed to
reduce assembly time and loose parts, the QT termination system
incorporates a connector body with a pre-assembled center contact,
termination is simple with no loose contact to drop or lose. QT pro-
vides a reliable gas tight connection between the inner conductor of
the cable and connector contact that meets the most stringent
industry standards. For PCB connectors a snap fit feature is incor-
porated into certain styles to hold the connector in position during
soldering.
Choice of Two Latching Styles – Standard or HDC (High Density)
ITT’s Cannon Type 43 / SMZ connectors are available in 2 package sizes, Standard and HDC (High Density).
Whilst both configurations have the same interface dimensions and are intermateable, the outer body size of
HDC is reduced to facilitate a closer packing density on the equipment or distribution frame.
Featur
es and Benefits
High performance gold plated
contact areas ensure reliable long
term operation
Posi-Lock locking mechanisms
ensure secure coupling and ease
of engagement and separation
Designed for the most commonly
used telecom cables in North
America and Europe
Designed for robust and reliable
field installation
A
vailable for BT
standard and HDC
distribution frames
Three-part construction with crimp
inner contact and outer ferrule (no
soldering required)
PCB Plugs come with of
fset legs
for board locking
QT (Quick termination) technology
available for most cable types
Product offering includes U-links
and between series adaptors
T
rue 75 ohm characteristic imped
-
ance up to 3 GHz (for selected
styles)
Most designs require no special
tooling
"T
eplock" mounting reduces the
time needed for fitting to DDF's
RoHS compliant part numbers
