Stäubli solar connectors: history, technology and models

Switzerland's Stäubli was founded in 1892 and took over Multi-Contact in 2002; MC4 is a protected Stäubli trademark, and the original connector requires the contacts, cable, tool and mating part of the approved family.

About Stäubli

HeadquartersPfäffikon, Switzerland
Founded1892; acquired Multi-Contact in 2002
Company typeSwiss group of mechatronic and connectivity solutions

Rudolph Schelling and Hermann Stäubli founded a workshop in Horgen, Switzerland, in 1892. The group grew in textiles, robotics, fluid connections and electrical connectivity.

In 2002 Stäubli acquired Multi-Contact, a connector company founded in Basel in 1962. MC4 photovoltaic technology became a reference in the portfolio; MC4 is a protected trademark, not a generic name for any similar plug.

  • Maker of the original MC4 photovoltaic connector
  • Its own industrial history and contact technology
  • Dedicated documentation, tools and assembly procedures

What to check before buying

Do not mate Stäubli MC4 with "compatible" connectors from other brands. Use the pair from the same family, the correct contact, an approved crimping tool, cable within the permitted range, crimp inspection and the cable gland torque.

Buying Stäubli equipment in Brazil

Check provenance and authenticity, as counterfeit or mixed connectors can have high contact resistance. Keep the packaging, part number and supplier traceability.
