In 1924, Telemecanique marketed its first bar contactor. The brand quickly expanded its activities to become the leading specialist in automation management, notable developing D contactors, which became a global reference. Schneider Electric acquired Telemecanique in 1988. In 2009, Telemecanique products, services, and solutions migrated to the Schneider Electric brand as its Automation and Control offer. They now provide complete solutions with a range of components including programmable logic controllers, variable speed drives and communications software. In addition, they offer power distribution through prefabricated busbar trunking. RSP Supply is a proud distributor of Telemecanique sensors.
