ODU is not just another connector manufacturer. It is the inventor of the Springtac® technology, a socket contact system that defines the gold standard for high-reliability connections. Founded in 1942 by Otto Dunkel in Mühldorf am Inn, Bavaria, the company remains a financially independent, family-owned business. From its 1,500-strong headquarters east of Munich, ODU maintains over 80% vertical integration, controlling everything from tooling and precision stamping to injection molding, turning, surface plating, and automated assembly under one roof.

The ODU portfolio spans circular push-pull connectors (ODU MINI-SNAP®, ODU MEDI-SNAP®), modular hybrid connectors (ODU-MAC® series for power, signal, and data), PCB connectors (board-to-board, board-to-wire), and heavy-duty connectors, all backed by custom cable assembly and wire harness services. ODU’s core Springtac® socket ensures minimal contact resistance, high mating cycles, and extreme vibration resistance, making its connectors the preferred choice for critical applications in military and security, medical technology, industrial electronics, automotive testing, and aerospace. The company holds a comprehensive suite of certifications including ISO 9001, IATF 16949, ISO 13485, ISO 14001, and ISO 50001, and its products are trusted globally where failure is not an option.
