Stäubli International AG was founded in Horgen, Switzerland in 1892 and today employs more than 6,000 people worldwide in the field of industrial mechatronic solutions. It is particularly strong in four business areas: electrical connectors, fluid connectors, robotics, and textile machinery.

Stäubli's activities in the solar energy market are mostly related to its electrical connectors business unit: the "Original MC4" connector family developed by the company has become an industry standard for DC-side cable connections in photovoltaic (PV) system installations. Stäubli offers eBOS (electrical Balance Of System) solutions that help ensure the long-term safe and reliable operation of PV systems — the company states that its connectors have connected more than 1,000 GW worldwide. In Stäubli's philosophy, industrial quality, reliability, and long-term support are key. This is also reflected in over 2,200 registered and pending patents.

In addition to PV-side solutions, the company is also strong in other industrial areas (e.g., robotics, quick couplers, automation), which shows that it is not merely involved in a narrow niche component, but possesses broad engineering expertise and a global presence.
