Company Profile
There are TT electronics products in every single military vehicle
deployed in conflict zones across the globe.
TT electronics plc is an international electronics company that has been supplying innovative high reliability components to the
military and defence markets for more than 30 years. The knowledge and experience gained in that time has been brought together
in a global team of designers and applications engineers dedicated to supporting the unique requirements of modern military
applications.Our industry experience and agile approach to business has given us a pre-eminent position in the supply of connectors
and other components to land-based military vehicles.
As a major plc listed on the London stock exchange, TT electronics plc has the financial resources to continually invest in
up-to-the-minute manufacturing facilities to address our customer’s needs and provide them with the correct solution.
With design and manufacturing plants in Europe and the USA, we are able to fulfil the Urgent Operational Requirements (UORs) of
defence forces globally with industrial and mil spec compliant connectorsand assemblies at exceptionally short notice.
In the harsh and unforgiving environment of the modern battlefield, it is essential that every single component is fit for purpose.
Working closely on site with our OEM and ODM customers has given our engineering team a deep understanding of the changing
market trends and requirements of land based military vehicles, enabling them to engineer the best possible component solution.

Land Rover
Unmanned vehicles
Security services
Electrical systems in the modern military vehicle
need to provide the user with a ruggedised
reliable solution to the interconnection issues
encountered in a battlefield theatre environment.
With high reliability being taken as a given we are
in the position to offer solutions to brave the most
demanding of applications.
Rotary wing aircraft
Military helicoptors
Search and Rescue
Commercial
helicoptors
Vibration and salt spray are just two of the hazards
facing military aircraft. We have developed a range
of screening products that allow the termination of
multiple screens in just such environments without
degradation to interconnection systems. Design and
manufacture of complex cable harnesses form part
of our core strengths. We are actively involved with
all systems within helicopter operations including
UOR activities system upgrades and role fits.

The requirement for electrical protection on military
platforms becomes even more critical as both the
natural effects of lightning and the effect of warfare
can play havoc with electrical systems in the air and
on the ground.
We provide cost effective electrical interface
systems designed to withstand the effects of EMC,
EMI, EMP and HIRF along with the harshest of
environmental conditions.

As the need grows for smaller systems we design
lighter, more compact interconnection systems
featuring miniaturisation of connector products
and lightweight wiring solutions. Screening
remains a high priority and a full range of connector
accessories for all styles of connector form part of
our portfolio to ensure design is not compromised
in any way
Civil aircraft
Landing gear

systems
Engine management
The civil aircraft market demands reliable
manufacturing processes. We produce critical
systems designed to ensure our solutions are in line
with those requirements. Cost efficient, light-weight
reliable solutions are an integral part of any design
specification.
We have a market leading technology in composite
systems, enabling your designers to enhance your
product offering to your customer.
Naval systems
Radar systems

communications
Panel assemblies
The issues facing naval applications bring a
whole new set of problems to the design of
interconnection systems. We offer screened cable
and conduit systems approved for “above deck full
threat EMP protection”. The ability to manufacture
interconnection panels and a component product
range offering salt spray protection, ensures
environmental issues are catered for during the
design process
