Founded in Switzerland in 1946, LEMO® took its name from the company's founder, engineer Léon Mouttet. Originally a manufacturer of contacts in noble and rare metals, the company took a major step forward in 1957 with the introduction of the push-pull self-latching connector.

Founder Wilhelm Harting recognised early that the emerging German industry needed technical products. Their committed employees and innovative ideas helped them work towards the goal of developing a connector that would be robust, easy to handle, and applicable for a variety of purposes. Wilhelm Harting had long recognised the need for such a product.
And soon thereafter, the Industrial Connectors Han® made its convincing market debut and went on to set a globally recognised standard. He has remained the backbone of the Technology Group during all its changes.Meanwhile, HARTING Technology Group has become a global leader supplying connectivity solutions for the three main lifelines of industrial technology – data, signals and power – with 14 production sites and 43 sales companies worldwide.
The company also manufactures electronic cash registers for retail use, electromagnetic actuators for automotive and industrial series production, charging technology and cables for electrical vehicles, as well as hardware and software for customers and applications in the automation, robotics and transportation sectors.
