Sekels GmbH

Sekels GmbH is a German company that develops, manufactures and trades technical products in the field of magnetism. According to its own description, it is a specialist for magnetic fields, magnetic materials, ring-band cores, magnet systems and magnetic shielding, covering everything from consulting through to the delivery of finished components and systems. The company operates with roughly 25 employees, nearly half of whom are physicists and engineers, and serves more than 600 customers worldwide. A central pillar of the business is distribution: Sekels acts as an authorized dealer of VACUUMSCHMELZE GmbH & Co. KG, offering customers extensive stockholding of semi-finished products, ring-band cores and components together with detailed technical advice. Beyond distribution, Sekels develops, designs and manufactures customer-specific solutions including core laminations and laminated stacks, magnetic shields and shielding systems, inductive components and magnet systems, from prototype through to series delivery. Its product and service portfolio also includes measurement and analysis systems for magnetic fields with high resolution and raw-data storage (such as the MFA-110), magnetic shielding design and manufacturing against low-frequency magnetic fields, a broad stock of NiFe and CoFe alloys in various dimensions with finishing, parts production and heat treatment, and ring-band cores and cut-band cores made from nanocrystalline (VITROPERM®), amorphous (VITROVAC®, METGLAS®) and crystalline alloys in standard and custom versions. The company also offers hydrogen annealing for magnetic optimization or soft annealing of stainless steels with sensitive surfaces. All parts, components and systems are manufactured in Germany or Eastern Europe based on technical documentation prepared by Sekels. The company is certified to DIN EN ISO 9001:2015 and states that it is familiar with all relevant norms and standards. Quality and environmental responsibility are emphasized, with customer satisfaction at the center of its activities. Sekels has pursued international expansion and partnerships, including a strategic agreement with the Chinese firm Lefeng announced in October 2024, and an expansion into a new market as a distributor of VACUUMSCHMELZE announced in November 2023. The company also participates in scientific and technical events, such as exhibiting at MicroTAS 2026 in Granada, and has been involved in projects related to the sustainable use of lithium-ion batteries.

Sekels GmbH is a German company that develops, manufactures and trades technical products in the field of magnetism. It describes itself as a specialist for magnetic fields, magnetic materials, ring-band cores, magnet systems and magnetic shielding, covering the chain from consulting to the delivery of finished components and systems. The company operates with approximately 25 employees, nearly half of whom are physicists and engineers, and serves more than 600 customers worldwide. A defining element of the business is its role as an authorized dealer of VACUUMSCHMELZE GmbH & Co. KG. Through this distribution activity, Sekels offers customers extensive stockholding of semi-finished products, ring-band cores and components, combined with detailed technical advice. In November 2023, the company announced that, as a distributor of VACUUMSCHMELZE, it was expanding its presence into a new market. Alongside distribution, Sekels develops, designs and manufactures customer-specific solutions. These include core laminations and laminated stacks, magnetic shields and shielding systems, inductive components and magnet systems, supplied from prototype through to series delivery. Its portfolio also covers measurement and analysis systems for magnetic fields with high resolution and raw-data storage, such as the MFA-110; magnetic shielding design and manufacturing against low-frequency magnetic fields; a broad stock of NiFe and CoFe alloys in various dimensions with finishing, parts production and heat treatment; and ring-band cores and cut-band cores made from nanocrystalline (VITROPERM®), amorphous (VITROVAC®, METGLAS®) and crystalline alloys in standard and custom versions. The company additionally offers hydrogen annealing for magnetic optimization or for soft annealing of stainless steels with sensitive surfaces. Manufacturing is carried out in Germany or Eastern Europe based on technical documentation prepared by Sekels. The company is certified to DIN EN ISO 9001:2015 and states that it is familiar with all relevant norms and standards. It emphasizes quality and environmental awareness, placing customer satisfaction at the center of its activities. Internationally, Sekels has pursued partnerships and new markets. In October 2024 it announced a strategic agreement with the Chinese company Lefeng. The company also engages with the scientific and technical community: it announced it would exhibit at MicroTAS 2026, the 30th International Conference on Miniaturized Systems for Chemistry and Life Sciences, in Granada, and it has highlighted work on precise magnetic manipulation of nanoparticles in 2D and 3D for research, diagnostics and microtechnology. In February 2025 it announced its participation in an innovative project concerning the sustainable use of lithium-ion batteries.
