Steha-Elektronik

What Steha-Elektronik does

STEHA-Elektronik GmbH is a private German electronics engineering and manufacturing firm founded in 1978, headquartered in Bessenbach near Aschaffenburg. The company specializes in the development and small-batch production of custom electronic control systems, embedded modules, and industrial automation solutions. Its product portfolio centers on two named offerings: the Rigel 91 Embedded Control Unit, built on an STM32F746 microcontroller and designed as a modular, service-friendly controller for industrial integration, and AquaDETECT, a leak monitoring system co-developed with medical-sector partners. The firm applies a modular system architecture emphasizing serviceability, component longevity, and integrated self-diagnostics, and serves customers in medical technology, automotive, nanotechnology, and welding.

The company's revenue model is B2B and project-based, with quote-based pricing tied to customer specifications. Service offerings span consulting, development, prototype construction, series production, and long-term maintenance, consistent with a contract developer and small-batch OEM model. Customer relationships include co-developed work with Fresenius Medical Care AG (a large dialysis and medical-products enterprise) and VIVONIC GmbH on the AquaDETECT platform. Geographical operations concentrate in the Rhein-Main corridor between Frankfurt and Würzburg, with the firm claiming worldwide service availability.

STEHA-Elektronik operates with approximately 30 employees under a private GmbH structure with no disclosed parent company, external shareholders, or funding rounds. It holds ISO 9001 quality certification and maintains GDPR compliance, addressing quality and data-protection requirements relevant to its regulated customer base. The firm has operated continuously for over 40 years, indicating business longevity but lacking verifiable recent scaling signals.
