The traditional brands Binder, Neue Hahn Magnet, Thoma Magnettechnik, Magnet AG, Linnig, Tri-Tech and Magneta, laid the foundation for the successful development of the Industrial Magnetic Systems Group.

The W. Binder Company was founded in 1911 by Wilhelm Binder. In the early 1920s, Wilhelm Binder began to develop and manufacture electromagnetic components, such as clamping devices, safety solenoids, solenoid drums and shift-lock solenoids. The product range was steadily increased, and productions plants were continuously enlarged.

In 1953, the first appearance at the “Hannover Messe” helped to gain international recognition. Over the years, more than 100 patents and utility models were registered. In 1997, the enterprise was sold to the Dutch group Schuttersveld N.V. – today known as Kendrion N. V.

Hahn Magnet was founded in 1952 in Inzigkofen-Engelswies by Fred Hahn. In 1966, the Company name was changed to Neue Hahn Magnet GmbH & Co.KG. Years of experience in the development and production of solenoids, especially in the area of door locking and safety technology, set the foundation for the Company's success. Since 1999, the Engelswies location belongs to the Kendrion Group. In 2001, the two locations Donaueschingen and Engelswies merged to form a limited liability company within the Kendrion Group. 

Thoma Magnettechnik was founded in 1965 in Brigachtal by Gerhard Thoma. Expansion forced the Company to relocate to Donaueschingen in 1968 - today home of the Magnetic Systems Group headquarters. As a specialist for shift-lock and holding solenoids, Thoma Magnettechnik gained an international reputation, and had great success, not least because of its customer-oriented solutions. In 2000, “Thoma” was acquired by Kendrion N.V.
