Encoders for measurement and control technology - since 1983

Expertise and technology leadership from the outset.

TR-Electronic develops, manufactures and sells sensors and actuators for industrial applications, primarily in automation technology. To enable the individual competencies to be focused more strongly, the company is organized into business units.

Products in the Rotary Encoders Business Unit with optical or magnetic scanning are required to detect the angular movement of a rotating shaft. Magnetostrictive linear encoders acquire the position of a linear movement - for example in a hydraulic cylinder - without contact. Intelligent compact drives from the Drives Business Unit are used as actuators or, in the high-end version, as process drives. Customized control and measurement modules in combination with special know-how in pressing and punching processes complete the program.

To ensure optimal customer proximity, in addition to its main location of Trossingen TR-Electronic has branches in Germany and subsidiaries and representatives worldwide.


A new building for more expansion on our site in Trossingen.


TR creates additional capacities for growth on the campus in Trossingen. The building "Im Sandbruch 1" gets a modern multi-purpose extension. The assembly area of me-tec GmbH (a TR subsidiary) will find new rooms on the ground floor, while the upper floor will temporarily be used for the development department of BU 02 (linear encoder) as offices to make room for the renovation work required in Eglishalde 6. The innovative functional building shows contemporary architecture and offers the latest equipment for flexible design of workplaces, be it offices or manufacturing.


The success story of the encoders with functional safety enters the next round: The SIL / PL certified encoders are now also available in a compact 58mm size. Safe encoders therefore fit wherever standard industrial encoders can be installed. Functional safety is no longer a question of installation space.


TR-Electronic develops the new generation of their compact absolute encoders. This provides a future-proof and powerful encoder system with all interfaces for Industry 4.0 for the industrial standard installation space of 58mm. The measuring systems are manufactured according to the principles of lean manufacturing with variable lot sizes. This enables highly individualized products with benefits tailored specifically to the customer.


German „TÜV“ accredits the TR environmental lab for examinations of vibrations, shock, EM, climate and water immersion behavior. Own tests for certification of components and devices are accepted by external certification authorities. Another proof of high value of own know-how for fast developments with high demands for quality.


TR-Electronic improves sales and support activities in BeNeLux in a new subsidiary in Geffen, NL. The local presence in the European neighborhood helps accessing the quite different markets in Belgium, Netherlands and Luxembourg. The own subsidiary is another consequent step integrating European sales activities into the common strategy of TR-Electronic.


TR supports the standardized data structure for safety approved devices by VDMA (VDM Standard 66413). Planners of safety functions easily find best suitable safety components for their applications in this database. By integrating openSAFETY via Powerlink into the SIL3 encoder series, TR takes another big leap for seamless safety integration.


In 2013 TR-Electronic will presented innovative solutions and series: CEV58M – the new generation of compact rotary encoders with direct connection to Industrial Ethernet; CMV36M – the "Mini" among rotary encoders: absolute multi-turn with connection for automation via SSI, Analog or DRIVE-CLiQ, industrial PC with all-glass touch system.

In order to meet future challenges and cope with increasing demand, production and development capacities will be expanded by a further 3000m2 and 30 additional jobs.


The introduction of SIL3/PLe-certified absolute rotary encoders with PROFIBUS safety via PROFIBUS marks the entry into Integrated Safety solutions.


TR-Electronic breaks new ground and expands the existing SIL3/PLe-certified encoders with the PROFIBUS safety fieldbus interface via PROFIBUS.


In order to further develop the Asian and Chinese market, the sales subsidiary TR-Electronic (Beijing) CO., LTD. is established in Beijing/China.

In the same year the LMC cascadable linear measuring system is successfully introduced onto the market.


Introduction of the SIL3/PLe-certified rotary encoder series for use in safety-relevant environments.


The two subsidiaries TR-Systemtechnik and UNIDOR merge to form TRsystems GmbH.
