Pepperl+Fuchs

Pepperl+Fuchs, founded in 1945 in Mannheim, Germany, is the world's leading manufacturer of electronic sensors and the dominant supplier of intrinsic safety barriers — the interface devices that make it legally and technically possible to run measurement and control signals into explosive atmospheres. The company invented the inductive proximity sensor in 1958 and has since built an unmatched sensor catalog: inductive, capacitive, photoelectric, ultrasonic and magnetic sensors, rotary encoders, position sensors for hazardous areas, and identification systems. Its industrial communication division supplies Remote I/O, HART multiplexers and fieldbus infrastructure that connect process instruments to control rooms in refineries and chemical plants, and its purge and pressurization systems protect larger electrical enclosures in explosive gas and dust environments. For valve automation specifically, Pepperl+Fuchs position feedback sensors, solenoid drivers and IS interfaces are standard equipment on actuators installed in ATEX and IECEx zones. The family-owned company operates manufacturing in Germany, the USA, Singapore, China, India, Indonesia and Hungary, and its blue-and-white products are recognizable in virtually every process plant on earth — a quiet ubiquity built on safety-critical engineering trust.
