AboutTT electronicsTT electronics plc is a global ectronics company that has beensupplying innovative high reliability components to the militaryand defence markets for more than 30 years. The knowledge andexperience gained in that time has been brought together in aglobal team of designers and applications engineers dedicatedto providing high reliability solutions for use in the most extremeenvironments. Our industry experience and agile approach tobusiness has given us a pre-eminent position in the supply ofelectronic components and integrated manufacturing servicesfor multiple military applications.
As a major plc listed on the London stock exchange,TT electronicsplc has the financial resources to continually invest in up-to-the-minute manufacturing facilities to address our customers’needsand provide them with the correct solution. With design andmanufacturing plants in Europe, North America and Asia we areable to fulfil the Urgent Operational Requirements (UORs) of defenceforces globally with COSH, proprietary, and mil spec qualifiedcomponentsand assemblies at exceptionally short notice.
In the harsh and unforgiving environment of the modernbattlefield, it is essential that every single component is fit forpurpose.Working closely on site with our OEM and ODM customershas given our engineering team a deep understanding of thechanging market trends and requirements of land based militaryvehicles, C4ISR systems and radio communications, enablingthem to engineer the best possible component solution.
There areTT electronics products in every single militaryvehicle deployed in conflict zones across the globe.

LandBasedVehiclesFamilyTT electronics’components division has multiple facilitiesfor the design and manufacture of interconnection systemswith engineering teams providing custom solutions.
Wheeled
TT electronics has worked with the major defence contractors involved inthe design and supply of wheeled military vehicle platforms for many years.The team has provided design, engineering and manufacturing expertisefor the electrical solutions required on the most advanced wheeled vehicles.The agility of the Connectors team in providing quick responses andsolutions has meant it has been involved in many of the UOR (UrgentOperational Requirements) seen recently. We have the ability to providehigh reliability connectors designed and manufactured to mil-specifications,in the harshest of environments. In recent years the Connectors BusinessUnit has focused on providing solutions from connector design tocomplete vehicle electrical systems.
Tracked
TT electronics has supplied integration kits under UOR to provide for addedtracked vehicle protection from IED’s. The increased power demand of thetracked vehicle fleets has enabled the Connectors team to design enhancedon-board power distribution systems. The design team has also worked withOEM’s to provide everything from unique connector designs for bulkheads allthe way through to complex box designs which provide the crew with controlover vehicle systems. We have supported many of our customers requiringfleet modernisation and role fit change programs.
Support
TT electronics has supplied many of the logistical and support vehicles fromthe FMTV and HMETT families in the USA, to the UK MoD’s Wolfhound. Theremit has extended to camera power & signal systems and providing powersolutions for air conditioning of kennels. Many of these vehicles have beenequipped with inverter systems to provide power management for soldierapplication requirements. TT electronics is also the prime supplier to NATOfor inter-vehicle power systems.

CaseStudies
In 2010 TT electronics was awarded a £2M contractto supply cabling and harnessing systems, as wellas racking systems to house communicationsequipment for over 100 Warthog vehicles destinedfor the Afghanistan theatre of operations.
TT electronics’reputation as market leaders in design, testand manufacture of harsh environment interconnectionsystems, bespoke harness assemblies and connectorswas a key factor in securing the contract.
ThalesTT electronics utilised its vertically integrated manufacturingfacilities to provide mil-spec connectors including D38999and backshells. In addition the team provided design andapplications expertise for vehicle fit and routing andsupplied all 100 plus systems to Thales.
Following this award TT electronics has gone on to supportThales on further vehicle projects including Foxhound.
Alex Cresswell, head of Thales UK’s land defence business,says, in a BBC news article“We look forward to working withTT electronics, and other highly capable companies basedin the area, to deliver this valuable capability to the UK ArmedForces. The Warthog vehicle, with its installed electronicsystems, represents a very significant military capability.”
TT electronics – Land Based Defence Vehicles 07
Background-Increased on-board power demands:The power demands present within today’s militaryground vehicles are nearly 10 times that of vehiclesfielded only 15 years ago.
The 50 and 60 amp alternators of the early 1990s havebeen upgraded to a minimum of 470 amps, and in somesituations vehicles are now sporting 680 amp alternatorsin order to supply power to an ever increasing array ofon-board equipment.
Customer-Specific Problem: U.S. Army Tank-automotiveand Armaments Command (TACOM) required TextronMarine and Land Systems to add an additional 160 ampsof on-board power into their US Army ASV (ArmouredSecurity Vehicle) in order to operate additional C4 and IEDcounter measure equipment. The additional power wasto be generated by a higher amperage alternator, however,the additional equipment being operated had to beprotected fromelectrical overload conditions, and thusthe demand for a separate power distribution module(PDM) was recognized during the project.
Design Demands: The PDM had to meet the environmentaldemands of every possible battle condition from arcticdesert to tropical jungle, along with the ability to remainoperational during extreme vibration and shock conditions.Space within any military armoured vehicle is always ata premium, and added to the geometric restraints in thissituation was a high ambient operational temperaturealong with resistance to diesel fuel and other chemicals.
PDMSolutionforTextronASVTT electronics solution: The TT electronics team met thedesign challenges head on, and was able to put a workingprototype of the PDM into the customer hands within 3weeks. As a follow on,TT performed stringent vibration andshock testing to the design in order to assist and solidifyTextron’s initial technical presentation to DOD engineers.The preliminary design met government approval, andduring the DOD trials that ensued, additional requirementswere identified such as circuit status indication and anadditional protective cover and added to the originaldesign. TT responded immediately with refinements eachstep of the way and eventually full TACOM approval wasgranted. Today the TT designed PDM and related cablesare a part of every production Textron ASV.
Benefits: TT’s design team reacted quickly to the customer’sproblem and did so with an emphasis on providing a ruggeddesign that went above and beyond the stringent designdemands, while at the same time meeting the customer’scritical timeline and budget constraints. An understandingof the government processes our customers must gothrough in order to present new technology into an existingplatform was key to the success of this project. TT’s designteam is always ready to quickly develop and implementproduct changes during the field trials process. As a result,the crew of the ASV in Afghanistan does not have to thinktwice about reliable circuit protection, regardless of theenvironment or harsh operational parameters around them.
