LEM Holding SA- Current Transformer Sensors

LEM Holding SA, headquartered in Geneva, Switzerland, is the world leader in electrical measurement for current and voltage sensing. Founded in 1972, LEM pioneered the use of Hall-effect current sensors for railway applications and has grown into a global group with four production centers in Geneva, Beijing, Machida, and Sofia. The company's core products include closed-loop current transducers (e.g., LA, LT series), open-loop current transducers (e.g., HAX, HAZ series), voltage transducers (e.g., LV series), and ASIC-based integrated sensors (e.g., LTS, LTSR series). These transducers serve a wide range of power electronics applications such as motor drives, renewable energy inverters, UPS, battery management, and automotive traction systems. LEM is recognized for its high accuracy, galvanic isolation, and wide measurement bandwidth, supplying components to industrial, railway, energy, and automotive markets. The group holds a dominant market share in industrial current sensing and is a key supplier to major EV and renewable energy OEMs. With R&D centers in Switzerland and Japan, LEM continuously innovates in fluxgate technology and high-isolation designs. The company is publicly traded on the SIX Swiss Exchange and employs approximately 1,100 people worldwide, generating annual sales of over CHF 200 million.
