JM Concept is a 27-year-old French PMI based in Brignais in the Lyon region since 1992.

We design, manufacture and market high-precision devices for insulating, measuring, converting, and transmitting process, electrical, and signals from various industrial sensors.

We are proud to count more than 800,000 devices in service, to date, worldwide.


Since our creation, we have never ceased to innovate and design, smart and connected devices in order to be universal, modular, reliable, and economically competitive.

Our goal is to do everything possible to optimize your measurement, conversion, transmission and isolation solutions.

Our technology represents the future of Industry 4.0 (IOT) by adding intelligence and connectivity to standard sensors, connecting them directly to the cloud or to any PLC through our communication hubs while maintaining an unrivalled isolation.


Our teams of engineers and salespeople, instrumentalists and automation specialists, listen to our customers to advise them, offer them customized solutions and help them implement their in-depth applications and specific processes.

Our solutions guarantee the reliability of your analogue or digital transmissions by Field Bus (Modbus, Profibus, Profinet...).

A rigorous selection of components, as well as individual, comprehensive and strict controls on our test benches, allows us to offer warranties from 5 to 10 years on all our products.

All our devices are made in France.
