What mk-messtechnik does

mk-messtechnik GmbH is a German limited liability company (GmbH) headquartered in Notzingen, near Stuttgart in the Swabia region. Founded in 1999 as a sole proprietorship and reorganized into a GmbH in 2010, the company designs, develops, and produces electronic test and monitoring devices for EMC (electromagnetic compatibility) laboratories. It is a first-generation family business, personally managed by Dr. Martin Kull and Katharina Kull, with no external investors or parent company disclosed.

The company's core technology is optical signal transmission for EMC testing environments — providing galvanic isolation between equipment inside shielded EMC test chambers and control room instrumentation. The product portfolio centers on optical extensions of automotive bus protocols (CAN-FD with Signal Improvement Capability, LIN, Automotive Ethernet 100/1000BASE-T1 via Marvell 88Q2112), EV charging communications (CCS1, CCS2, PLC), digital/industrial interfaces (USB 2.0, RS232/422/485, SPI, I2C, UART, TTL, GPIB), Ethernet standards (10BASE-T1S through 10GBASE-T), intercom systems for EMC chambers (dAV-TRX), and supporting accessories such as media converters, shielded enclosures, camera systems, and 19-inch rack-mount units. Products are built in-house with high production depth, including pick-and-place PCB assembly and custom aluminum housing machining. The company holds RoHS and REACH compliance declarations and partners with chipset vendors (NXP, Marvell, Valens) and test equipment firms (Schwarzbeck, SesKion, Vector Informatik) for technology integration and validation.

mk-messtechnik operates a B2B direct sales model, selling to EMC test laboratories, automotive OEMs and suppliers, aerospace firms, and industrial manufacturers worldwide. Revenue is generated through hardware sales of standard catalog products and custom/OEM system development. Pricing is not publicly disclosed and quotes are provided on request, with standard delivery cycles of approximately 8 weeks from contract conclusion. Distribution is direct from the Notzingen warehouse, with marketing conducted through the company website (mkemc.com), a bilingual (German/English) newsletter, and direct sales contact. Headcount exceeds 60 employees, with more than one-third in development, and the company has expanded its physical footprint twice (2014, 2018) to accommodate growth.
