Adels Contact

What Adels Contact does

Adels-Contact Elektrotechnische Fabrik GmbH & Co. KG is a privately held, family-owned German industrial manufacturer headquartered in Bergisch Gladbach, Germany. The company develops, produces, and distributes electrical terminal blocks and pluggable connectors for three primary use-case segments: lighting manufacturers (luminaires, LED modules, street lighting, continuous-row systems), building technology (permanent electrical installations compliant with EN 61535), and electrical appliance manufacturers. Its product portfolio spans screw and push-in terminal blocks (500 Series, LK-980-3), specialized connector systems (the proprietary AC 166® G building installation system, AC 164 compact system, AC 162 for LED/low-voltage), IP66/IP67/IP68 circular connectors and connection housings, the LEDtrack continuous-row lighting system, ZHAGA Book 18 street lighting connectors, and the terminaLED distribution box. Differentiated features include tool-free push-in connection technology, 70% installation time and 30% cost savings with the AC 166 G plug-and-play system, and compliance with EN 61535, DIN VDE 0100, and Zhaga Book 18 standards.

The business model is a straightforward B2B hardware-sales model: products are priced per unit on an ex-works basis with a EUR 100 minimum order value, 30-day payment terms, and surcharges on opened packaging units. Adels-Contact combines a direct sales team in Germany (with dedicated Sales Managers for OEM and Building Installation) with an expanding international distribution network — Ineltro AG covers Austria and Switzerland, OMEGA Group covers Italy, Spain, France, and Portugal, and TOP Electronic Components S.A. covers Greece. The customer base includes blue-chip European manufacturers and distributors such as Signify, Schreder, Siteco, Erco, Bega, Conrad Electronic, Stiebel Eltron, Brennenstuhl, Clage, and Insta. Ownership rests with Johann Hans Hochköppler (President) and Andreas Patrick Rumpff (Managing Director); the company is structured as a GmbH & Co. KG limited partnership with no external institutional investors or venture/PE involvement, operating with 51-100 employees on a self-funded, organic-growth basis. Revenue is generated through unit-based sales of certified, design-in connector and terminal-block components into long-lifecycle OEM and building-installation applications across Europe.
