What Senis does

SENIS AG is a Swiss precision instrumentation company headquartered in Baar (Zug), Switzerland, specializing in high-accuracy DC and AC magnetic field measurement and current sensing. Founded in 2004 as a spin-off of SENTRON AG (later acquired by Melexis), the company commercialized proprietary integrated 3D Hall sensor technology — the only single-chip 3-axis Hall probe with integrated amplifier worldwide — and built a portfolio spanning analog and digital teslameters/gaussmeters, all-in-one 3D magnetic field mappers (including the SENCAM magnetic field camera), Hall probes, and closed-loop and open-loop current transducers. The company operates a Class 1'000 cleanroom, an ISO/IEC 17025:2017 accredited calibration laboratory (one of only a handful worldwide certified up to 1.5T), and a 50+ employee group across Switzerland, Serbia, and regional sales offices in China and Japan.

Its commercial model is enterprise B2B, selling high-value capital instruments via request-for-quotation with configuration-based pricing, complemented by recurring calibration services (DC, AC, orthogonality) and a patent licensing stream. Revenue is generated across six named primary verticals — automotive and e-mobility (Porsche Formula E quality control), robotics and humanoid robots, defense/aerospace/space, energy and power electronics, industrial motors and appliances, and medical/scientific research. Reference customers include Porsche, Siemens, ABB, maxon motor, Nidec, CERN, the Paul Scherrer Institut, Bruker BioSpin, SLAC, and Germany's PTB. In July 2025 SENIS AG was acquired by the Swedish Nilario Group following a corporate split that placed the sensor IP and licensing business in a newly independent entity, SENISENS AG, with SENIS AG retaining the high-precision instruments franchise and acting as long-term exclusive supplier to its former sister company.

Scale indicators5 records

Recent moves10 records

Expansion highlights6 records

Broad incumbents

• Keysight Technologies: Global leader in electronic test and measurement instrumentation. Competes broadly with SENIS in test & measurement categories, but does not specialize in magnetic field-specific instrumentation and serves different scale of customers.
• Rohde & Schwarz: German-headquartered broad-line test & measurement incumbent with extensive product portfolio across RF, EMC, and power electronics testing. Indirect competitor in adjacent precision measurement categories; far larger and broader than SENIS.

Direct peers

• Lake Shore Cryotronics: US-based manufacturer of precision cryogenic and room-temperature measurement instruments, including Hall effect measurement systems, teslameters, and magnetometers. Closest direct competitor to SENIS in high-precision magnetic field measurement with overlapping customer base in research and industrial labs.
• Hirst Magnetic Instruments: UK-based manufacturer of precision teslameters, gaussmeters, and Hall effect probes. Direct competitor in precision DC/AC magnetic field measurement for research and industrial customers.
• Metrolab Technology: Swiss-headquartered manufacturer of high-precision NMR teslameters and magnetometers, including 3-axis Hall probes. Direct competitor in the same geographic and product niche as SENIS, particularly for laboratory-grade magnetic field measurement.
• MAGNET-PHYSIK Dr. Steingroever: German manufacturer of gaussmeters, teslameters, and magnetic field measurement systems. Direct competitor in industrial and laboratory magnetic measurement, with overlapping customer base in motor and magnet manufacturing.
• Brockhaus Measurements: German manufacturer of measurement systems for magnetic properties of electrical steel and soft magnetic materials, including Epstein frames and DC measurement systems. Comparable to SENIS in serving motor and magnet QA applications with precision magnetic instrumentation.

Emerging players

• Melexis: Belgian semiconductor company specializing in Hall sensor ICs for automotive and industrial applications. Historically linked to SENIS via the 2004 acquisition of SENTRON AG; comparable in underlying Hall sensor IP but different end-market focus.
• TDK-Micronas: Subsidiary of TDK focused on Hall-effect magnetic sensors for automotive and industrial applications. Comparable in Hall sensor technology to SENIS but serves high-volume embedded applications rather than precision measurement instrumentation.
• SENISENS AG: Formed in July 2025 as an independent spin-off from the SENIS Group, SENISENS AG focuses on advanced magnetic sensors and sensor modules. Sister entity and historical licensee of SENIS AG technology, with adjacent rather than direct overlap in product portfolio.
