Comtronic GmbH Verbindungstechnik

What Comtronic GmbH Verbindungstechnik does

Comtronic GmbH Verbindungstechnik is a German privately-held manufacturer and distributor of electromechanical connectors headquartered in Heiligkreuzsteinach, Germany (Mannheim registry, HRB 336496). Founded in 1968 as a distribution and trading company for electromechanical components, the firm transitioned into in-house connector manufacturing in 2000, producing to MIL-DTL-83513 and EN9100 aerospace quality standards from a facility equipped with automatic lathes, high-precision milling, mold making, injection molding, cable and connector assembly shops, and a clean room class 5000. The company is family-owned and managed by Geschäftsführer Dirk Lehmann, with Lutz Lehmann overseeing production and Vivien Lehmann-Rajs handling accounting and HR.

The product portfolio centers on two proprietary families: the MicroCom series of miniature circular connectors (CMR, CMRM, CMRH variants) with metal housings providing EMC shielding across 5.0-18mm diameters, 2-12 positions, -55°C to 250°C temperature range, up to 2,500 mating cycles, and (added in 2024) up to 1Gbit/s high-speed data transmission; and the Micro-D series of miniature rectangular connectors (CMK, CMD, CMD M1) built to MIL-DTL-83513 with Twist-Pin contacts for high shock and vibration environments. Supporting offerings include EMC-filtered MicroCom variants, Micro-D backshells with 30% weight and space savings, custom backplanes and NANO coaxial connectors (1.2mm diameter, aircraft-qualified), full cable assembly services with 100% electrical testing, a procurement service for discontinued MIL-qualified components leveraging 50 years of archived standards (including supply from Bendix, Souriau, Amphenol, Continental Connectors, Thorn, Malco), and distribution of heat-shrink and braided sleeving from CANUSA and Raychem.

Comtronic serves aerospace, military/defense, and industrial sensor customers through a sales-led B2B model combining a direct sales team with named account managers from German headquarters and an authorized international distributor network spanning Italy (via subsidiary Comtronic srl and AFAR srl), the USA (FDH Electronics), the UK (Air & Marine Products), Hong Kong (Phoenix), Switzerland (ABM Elektronik), India (SM Creative Electronics), and South Korea (PANKO Trading). Revenue is generated primarily through hardware sales of proprietary connectors and custom-engineered solutions, plus ancillary distribution of third-party MIL connectors and heat-shrink products, with quote-based pricing and no publicly disclosed financials. Quality is anchored by DEKRA-verified ISO 9001 certification and EN9100 aerospace manufacturing compliance.
