Cannon 75 Ohm Connectors
Type 43 (SMZ)
ITT’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.
Designed 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.
Applications
• Switching Equipment • DSX Cross Connects • Base Stations • Routers • Wireless • Telecom • LAN Equipment
