Arnold Electronic GmbH

What Arnold Electronic GmbH does

Arnold Electronic GmbH is a third-generation, family-owned custom electronics manufacturer founded in 1932 and headquartered in Lichtenau, Germany. The company produces exclusively to customer order, with no standard catalog, across three product families: inductive components (chokes, coils, transformers, and converters, with over 6,200 variants spanning 12 g to 120 kg and frequencies from 50 Hz to 1 MHz), cable assemblies (including UL-certified ZPFW2/ZPFW8 harnesses for the US/Canadian market), and module/electromechanical assemblies including encapsulation, coating, and functional testing. Manufacturing employs modern automation, including a precisely calibrated tinning robot ('Robby') and a recently expanded production area of 400 m², with quality managed under ISO 9001:2015.

The business operates a direct, sales-led go-to-market targeting enterprise industrial clients, R&D departments, and procurement teams across power electronics, medical technology, and electronics manufacturing. Named customers/partners include Siemens AG, BIOTRONIK SE & Co. KG, Gustav Klein, Assmy & Böttger, AST Group, and ZED Ziegler. Pricing is quote-based on each specification with no public list prices; revenue is generated one-time per project with no disclosed subscription or recurring model. The company is concurrently pursuing the SoundProtect research project, which applies AI-based acoustic signal processing to an autonomous stove protection system for grazing animal welfare.

Arnold Electronic is a privately held GmbH (legal name confirmed; no stock symbol), with no external investors, parent company, or subsidiaries disclosed in the source data. Ownership and CEO duties reside with Marion Arnold-Sittig. The firm claims worldwide direct sales reach, anchored by its UL certification for North American cable assemblies.
