ELSOMA

What ELSOMA does

ELSOMA GmbH is a German specialist in magnetization and magnetic measurement technology for permanent magnets, headquartered in Schwerte with 11-50 employees. Founded in 1989, the company develops and manufactures magnetizing devices (ELSOMAG series, including the 230 C4 EEM and the IIM2k impulse head) and high-precision measuring instruments (ELSOTEST A05, A01, C10 flux density meters, H1-4 field strength meter, B2 fluxmeter) used for quality assurance in production environments. Its technology enables precise multipolar magnetization of all common hard magnetic materials (AlNiCo, ferrite, SmCo, NdFeB) and achieves measurement uncertainties below ±1.25% on its A05 device, with active participation in DIN SPEC 91411 and 91479 standards development.

The company's product portfolio spans hardware instruments, simulation services (using Simcenter MAGNET for 3D FEM analysis), contract magnetization (Lohnmagnetisierung), and customized automation solutions for series production. It serves seven primary verticals: magnet manufacturers, sensor manufacturers (XMR/Hall sensors), position encoder manufacturers, electric motor manufacturers, automotive OEMs and suppliers, material suppliers, and machine/plant builders. Named customers include Volkswagen, Siemens, BJ Automotive, ITK Dr Kassen, elobau, Reckmann, and Hehnke. Distribution is primarily direct sales supplemented by an exclusive partnership with NDK (Nihon Denji Sokki Co. Ltd) covering DACH and Benelux markets, signed in March 2025.

ELSOMA generates revenue through capital equipment sales, contract magnetization services, training, and repair/maintenance, with quote-based project pricing. The company is a wholly owned subsidiary of Dr. Slatter Holding GmbH since April 2023, ISO 9001:2015 certified, and reported a record result in 2022. It markets primarily through industry trade shows (Coiltech, SENSOR+TEST, IKMT, World Magnetic Conference) and industry associations (AMA, INNOMAG, UK Magnetics Society).
