LEM Parts & Automation Components

LEM was founded on February 1, 1972 in Geneva, Switzerland by engineer Jean-Pierre Etter, originally as Liaisons Electroniques-Mécaniques LEM SA. Its first product was a 300A current transducer built for Swiss trolleybuses, using non-contact Hall-effect measurement to solve a problem existing methods couldn't: safe, accurate current sensing on high-voltage rail systems. The company went public on the Swiss Exchange in 1986 (ticker LEHN) and has grown into the global leader in electrical parameter measurement, with production plants in Switzerland, Bulgaria, Japan, Malaysia and China, and over 50 years of expertise in current and voltage transducer technology used across industrial automation, drives, renewable energy and traction applications.
