In the 1990s the electronics activities were expanded with the acquisitions of the Magnetic Materials Group, AB Electronic Products Group and BI Technologies.[4]
Further expansion was made with the purchase of Dale Electric International in 1994,[6] and the AEI Group, which was the Wire and Cables Division of the General Electric Company, in 1997.[7]
In 2000, the company changed its name to TT Electronics plc.[8]
The company bought New Chapel Electronics, a manufacturer of interconnection systems for the aerospace industry, in 2008[9] and the Power and Control business of Ferranti Technologies, a manufacturer of mission-critical power and control sub-assemblies, in 2022.[10]
