STAC

What STAC does

STAC (STAC Elektronische Systeme GmbH) is a German developer and manufacturer of high-precision PC-based measurement systems, founded in 1983 and headquartered in Tönisvorst, Germany. The company designs modular data acquisition systems, FFT analyzers, and complete test solutions focused on brake noise, vibration, and performance measurement for the automotive industry. Its flagship EventScan platform comprises EventScan CAR (compact in-vehicle testing) and EventScan RIG (test bench measurement supporting up to 48 high-speed channels), with compliance to AK Standard, SAE J2521, and EKB test procedures. Historical credibility extends to aerospace (Ariane V turbopump vibration analysis, 1996) and medical technology (EMBOtec emboli detection, 1994).

The product portfolio spans complete brake test systems, compact USB measuring modules (SPDuo, SPQuad, SPX), wheel-side accessories such as the SRS slip ring and MSM multisensor module, and an array of sensors (microphones, accelerometers, pressure, humidity, and pedal travel sensors). The business is held in founder family ownership, with Dr.-Ing. Andreas Bender and Dipl.-Ing. Dipl.-Wirt. Ing. Dennis Bender serving as managing directors and an 8-person team covering hardware development, software, production, and service.

STAC operates a sales-led, quote-based enterprise model, selling customized measurement solutions directly to global automotive OEMs, brake system suppliers, and brake/damping material manufacturers across the US, Europe, and Asia. With over 500 EventScan systems installed worldwide, the company sustains itself as a profitable niche specialist without disclosed external funding. Distribution is direct, supported by industry event participation (notably Eurobrake 2023), the corporate website, and personalized consultation via phone and email.
