Company History

It all started in a basement: In December 1958 Klaus and Irma Hantke registered the tetronik Klaus Hantke VDI as an engineering office in Frankfurt.

When our founder decided to set up his own company, he did so in order to be able to meet special customer requirements in the field of communication through his own developments as a committed engineer.

In the 60s, special components based on transistor technology were developed and manufactured to complement personal search radio systems.

As early as 1964, the current company headquarters were built in Taunusstein-Wehen.

After a part of the company had been spun off in 1971 as 'tetronik Vertriebsgesellschaft mbH', today 'tetronik Kommunikationstechnik GmbH', in the 70s, tetronik GmbH concentrated on the development and production of trend-setting telephone couplers.

These were initially based on TTL, then CMOS and then microprocessor technology.

In 1980 the series delivery of the universal personal search adapter UPSA 80 began – a product milestone.

This was followed by a close cooperation with Siemens AG and the delivery of a wide variety of HW/SW special solutions based on analog telephony: multi-channel paging couplers, hotel guest alarm systems, alarm servers, guard control systems, broadcast and conference systems and much more.

1994 – birth of DAKS: The first DAKS generation based on ISDN was developed and an OEM agreement was concluded with Siemens AG for the worldwide marketing of the alarm server "DAKS for Hicom".

In 1995, company founder Klaus Hantke handed over the tetronik company to the long-standing employees Rainer Seelgen (CEO), Heiko Trapp (CEO) and Horst Grünewälder (ppa) as partners of 'tetronik GmbH Angewandte Elektronik und Nachrichtentechnik'.

This was followed by the introduction of a QMS according to ISO 9001 in 1996. As early as 1999, tetronik entered IP telephony as an OEM product for Siemens AG with a 30-channel VoIP gateway RG2200.

In 2003, the strategic partnership with Impact Technologies, St. Louis, began for the marketing of DAKS in North America. In the following years, the DAKS system was constantly improved – towards VoIP.

DAKS was marketed extremely successfully via Siemens in conjunction with HiPath 4000 and cordless E, especially in the health care sector. In 2008, the long-standing employees Markus Heeser, Jens-Peter Lichtenberg and Hartmut Luetz-Hawranke joined as shareholders.

The compact DAKSeco alarm server and satellite components for contact I/O, serial I/O, NF I/O expand the DAKS portfolio. Partnerships in heterogeneous ICT system environments are being further expanded.

A further generation change takes place in the management: Winfried Geutsch joins as managing partner in 2012 and shortly afterwards the former managing director Rainer Seelgen retires.

Certified as a medical device manufacturer according to ISO13485 since 2013, tetronik introduced DAKSmed 2016 as a medical device.

In 2017, the company headquarters were further enlarged and a new training centre was built.

Based on a stable market presence and a team of abuot 40 committed employees, tetronik works on the further development and expansion of strategic partnerships worldwide as well as on innovations in hardware and software and on the expansion of the tetronik portfolio in the areas of process optimization, personal security and emergency, alarm and crisis communication.
