What sensortechnik wiedemann gmbh does

Sensor-Technik Wiedemann GmbH (STW) is a German private limited company headquartered in Kaufbeuren, Bavaria, founded in 1984 and operating under the Wiedemann Group holding structure. The company designs and manufactures electronic control units, sensors, connectivity gateways, power distribution modules, human-machine interfaces, and software solutions for the digitalization and automation of mobile machinery. Its modular product architecture is organized around three hardware pillars—ESX programmable control units, TCG connectivity gateway modules, and a broad sensor portfolio (pressure, temperature, strain, IMU)—complemented by the MACHINES.x software platform (cloud, access, insight, analytics) and electric drive components including powerMELA synchronous machines and battery management systems supporting up to 800V and 2000A.

STW's technology stack combines ruggedized hardware for harsh mobile environments with an open software layer (openSYDE toolchain, MACHINES.cloud, MACHINES.analytics) that integrates with AWS for AI/ML workloads. The company addresses functional-safety-critical applications, evidenced by safety-rated pressure sensors (F02) and safety-certified controllers used in braking and autonomous functions, alongside cyber-security capabilities (OTA update bundle, active PSIRT with advisories in 2023-2025).

STW generates revenue primarily through hardware sales to OEMs, supplemented by subscription-based software (MACHINES.x platform), professional services for field application engineering, and e-mobility component sales. Go-to-market combines direct enterprise sales with a global network of system integrators and distributors, supported by regional offices in Berlin, Chemnitz, Ulm, and a wholly-owned subsidiary in Shanghai. Customer base spans agricultural machinery (AGCO Fendt, ROPA, Krone), construction equipment (BAUER, Tadano, KUKA), municipal technology (DINTEC, HJS), marine (Zebotec, Prague Boats), commercial vehicle electrification (Pepper Motion), and airport ground support (Goldhofer, MAFI TREPEL). Pricing is quote-based with multi-year OEM contracts; no list pricing is publicly disclosed.

Core offering

Sensor-Technik Wiedemann (STW) designs, manufactures, and supplies electronic control units, sensors, connectivity gateways, power distribution modules, human-machine interfaces, and IoT/cloud software solutions for the digitalization and automation of mobile machinery. Its modular product system serves OEMs across agricultural, construction, municipal, marine, airport ground support, and commercial vehicle electrification industries, providing both generic and customer-specific hardware, systems, and software offerings.

Product overview

STW offers a modular system of generic and customer-specific products, systems, and software solutions for the digitalization and automation of mobile machinery. The portfolio is organized around three core hardware platforms: ESX programmable control units (ESX.4cl-ag, ESX.4cl, ESX.4cm, ESX.4cs, ESX.4ct, ESX.3cm, ESX.3cs) and associated I/O modules (ESX.iom, ESX.3ios, ESX.iot, ESX.mbc); TCG connectivity gateway modules (TCG.nano, TCG-4, TCG.5) for machine-to-cloud communication; and a comprehensive sensor portfolio including pressure sensors (F02, M01, SMX.pt series), pressure switches (P01), temperature sensors (T01), strain sensors (SMX.dms-a), IMUs (SMX.igs-e, SMX.igs-a), and sensing elements (OEM, OPTI, OPTI-H2). Power distribution is handled by BCX body control units and ZEX central electrics modules. The software ecosystem centers on MACHINES.x platform comprising MACHINES.cloud (fleet and data management), MACHINES.access (remote VPN access), MACHINES.insight (device configuration and diagnostics), and MACHINES.analytics (predictive maintenance via machine learning). The Basic IoT Bundle provides cloud connector enabling AWS AI integration. Additional products include openSYDE development toolchain, HPX.ai-vision for computer vision, powerMELA electric drives, and BMS battery management systems. The ecosystem is complemented by VSX professional displays and cyber security solutions.
