Since its founding in 1951, WAGO has been pioneering innovative connection systems in electrical engineering and electronics. ... The idea for the first WAGO terminal blocks was born in 1951; the first terminal blocks with spring clamp termination technology were presented at the Hanover Fair the same year. Precisely designed and manufactured, spring-loaded connections not only guarantee a faster and easier connection, but also offer a higher safety level since the contact quality is largely independent of operator skill. WAGO is the leading specialist of spring clamp termination technology and is providing components for automation technology. In 1977, the success story of the CAGE CLAMP® began – “vibration-proof, fast and maintenance-free connections.” Safe operation for many devices, systems and installation depends on the unconditional reliability of our products. read more
