About Us - Profile / History
Tyzack Turner Group plc, a company listed on the London Stock Market, was renamed TT Group plc in 1988. From 1988 to 1989 the company made a number of acquisitions before entering the electronics industry with the takeover of Crystalate Holdings plc in 1990.
TT Group plc transitioned to become a global manufacturer of specialist and niche products with further acquisitions during the 1990s. During this time the electronics activities were expanded with the acquisitions of the Magnetic Materials Group, AB Electronic Products Group and BI Technologies. Further expansion was made with the purchase of Dale Electric International and the AEI Group, the Wire and Cables Division of GEC.
In 2000 the company changed its name to TT electronics plc to more closely reflect the structure of the Group and the future direction. Also at this time a number of acquisitions made in the period from 1987 to 1990 were de-merged. The Group's major electronic activities became automotive sensors and systems, electronic components and electronic manufacturing services (ems). In addition the Group manufactured power systems, cables, wire and cable accessory products.
New acquisitions since the change of name to TT electronics plc have been focused on electronics. Optek Technology was added to the sensors and electronic systems division in 2003, bringing active components in the field of opto-electronics to the Group.
In 2004 TT electronics purchased Sensopad, a small technology business based in Cambridge which developed Autopad®, the automotive sensor technology.
The purchase of Dage, an ems business based primarily in China, in 2005 gave a platform for expansion in the region and created further low cost manufacturing capability for the ems division. This was followed by the purchase of Apsco in 2006, completing the creation of a global footprint for our ems activities. Both Dage and Apsco have subsequently been renamed. Operations are now based in the UK, USA, China and Malaysia and form what is now our Integrated Manufacturing Services division.
During 2007 TT electronics purchased the rights to DAPS (digital angular position sensor), a new sensor technology and sold the AEI Cables operation based in the UK.
In 2008 the purchase of New Chapel Electronics, a UK based company which designs and manufactures specialist interconnection systems for the aerospace and defence markets, provided an opportunity to complement TT electronics' successful and growing interconnection systems business by providing improved sales channels to the high margin military and civil aerospace sectors.
This was followed by the acquisition of Semelab, which designs and produces specialised radio frequency and power semiconductors, optoelectronic components and power microcircuits and modules, thereby expanding the Group's electronic component activities.
With effect from 1 January 2009, the Group was re-organised into the following divisions:
- Components
- Sensors
- Integrated Manufacturing Services
- Secure Power
- General Industrial
TT electronics specialises in supplying electronics for a global customer base from major manufacturing locations worldwide.
