LEM International (LEM Holding SA / LEM SA, Meyrin/Geneva) is the global market leader in current and voltage transducers — contactless sensors that let power electronics, EV drivetrains, chargers, renewables inverters, rail traction and industrial-automation equipment measure electrical current without breaking the circuit.
Named counterparties identified by open-source research and written only where a primary source states the relationship — never inferred from sector or co-mention. 1 customer-side. This is a partial view: it covers the relationships we could evidence, not the company's full supply base.
LEM co-designed a customized HAH1 open-loop Hall-effect sensor, then a LEM Nano current sensor, integrated into Semikron Danfoss's DCM (Direct Cooled Molded) SiC power-module platform (750V/1200V, 200-800A) for EV traction inverters. LEM's own press release; a design-partnership/customer relationship, not a raw-material supply agreement.
Scope. Absence of a counterparty here is not evidence that none exists — most commercial sourcing is confidential and never becomes public. Rows without a share figure mean no share was disclosed, not that the relationship is small.
Every exposure is read as a buyer dependency; the top 3 are its binding chokepoints.
As a buyer, policy pressure across its consumed materials is rising.
Descriptive trend in official policy actions on this company’s materials — a policy-pressure trend, not a price or trading signal. No forward probability is implied. Direction is measured on actions we have discovered, and discovery lags events: where the recent window is too thin to support a calm reading, the row says coverage-limited instead of easing.
No actions in the register have named or swept this company in the last 24 months.
