About us

We have been designing and producing electronic devices in Schwaebisch Hall for more than 40 years. Our first design was a Thermistor-Relay. Since this time, our range of products has enlarged continually. For instance we have devices that communicate via Internet.


Our electronic devices for industrial systems are innovative, future-oriented and renowned for top quality. Working to the highest technical benchmarks, we develop and produce using state-of-the-art systems and under a demanding quality management system. We are pioneers in producing electronic devices for modern and reliable measurement, control and regulation technology to meet every requirement – be it in industrial applications, companies, private homes or rented buildings. Goals such as sustainability, energy efficiency and maximum economic efficiency can be ideally achieved using our products. The highest of standards when it comes to commitment for our customers make us the ideal partner for business and industry. Our products are made in Germany. Our operations are certified in accordance with both ISO 9001:2015 and ATEX directive 2014/34/EU and are subject to regular monitoring for UL-approved devices.

The focus of our product range

Monitoring devices to protect the winding temperature of electronic motors against unpermitted heating. A range of extended monitoring applications, for example for transformers, storage and other temperatures. Temperature sensors such as PTC thermistor temperature sensors or all types of resistance thermometers and thermocouples.

With phase, voltage, current and frequency relays. Market leader with the UFR1001E, certified for grid and plant protection and approved for Germany, Austria and Great Britain, as well as the SPI1021 for Italy.

For measuring various signals. For use anywhere that measured values are to be displayed. Alarm outputs and integrated measuring transducers expand the range of uses.

Innovative controls for extraction systems, speed monitors and level relays for conductive liquids.

Measuring transducers for temperature and electrical quantities, such as AC and DC current, voltage or resistance, isolating amplifiers and measuring point changeover switches round off our complete range of products.
