(Coax Surface Mount MID) 75 ohm connectors use molded
interconnect device technology – a process which allows the selective
metallization of 3D plastic shapes. Two, three or four coaxial
connector lines can be integrated into a single surface mountable
module. The modular design means that designers can incorporate more coax
lines on a card edge than ever before.
QT - Quick Termination Connectors
Quick Termination connectors have the special QT contact
pre-assembled into the main connector assembly, which eliminates
the process of crimping or soldering onto the center conductor of a
cable. The center conductor is terminated to the inner contact within
the connector assembly, by activating the QT (patented) mechanism
using the simple plastic tool provided. The assembly is completed in
4 simple steps.
1. Strip cable using standard tooling.
2. Assemble connector on to cable.
3. Press insulator into connector body.
4. Crimp the ferrule using standard hex crimp tool to
complete the termination.
The QT principle may be applied to 50 Ohm products also. Contact
our Customer Service group for more information.

CABLE ASSEMBLY SERVICE
Cannon has a precision cable assembly facility for the manufacture and testing of a wide range of cable / connector
assemblies. By using Cannon's considerable expertise in this field, the customer is relieved of expensive training, tooling
and reject problems. This invariably offers economic and logistical advantages when compared to user assembly.
Flexible, semi-rigid and Sealflex 2 RF and microwave coaxial cable assemblies for DC to 40 GHz are manufactured to the
most complex customer designs and exacting mechanical and electrical tolerances. A full range of MIL-C-17G proprietary
flexible and semi-rigid cables are used as well as the Sealflex 2 fully flexible, low loss microwave cable. With computerized
semi-rigid cable forming and Vector Network Analyzer test equipment cable assemblies are manufactured for quality
conscious customers the world over. Our skills, experience and 100% electrical testing allow us to build products that meet
or exceed expectations.
75 OHM CONNECTORS
Cannon also offer a wide selection of 75 Ohm connectors for switching and transmission in telecom applications. These
include the popular Type 43 (SMZ), 1.0/2.3, 1.6/5.6 and BNC connector ranges incorporating the CoSMID ™ surface
mountable modular technology and the (patented) ‘QT’ quick termination designs. The CoSMID modular design allows
designers to incorporate more coax lines on a card edge than ever before and the QT assembly eliminates the process of
crimping or soldering onto the centre conductor of the cable.
FAKRA CONNECTORS
In addition to the range of SMB connectors we also offer FAKRA connectors for automotive applications.
