Stäubli Electrical Connectors

Precision Engineered Electrical Connector Solutions


Stäubli Electrical Connectors (Stäubli Group) is a Swiss-based leading manufacturer of electrical connectors and contact systems, providing innovative solutions for demanding applications. Stäubli Electrical Connectors builds on more than 50 years of engineering and design experience to continually break new ground in the field of advanced contact technology.

The Stäubli, product range includes interconnection systems for the most demanding applications in aerospace, medicine, robotics, solar energy, general industry and test and measurement. Our plugs and sockets are designed for high performance, high mating cycles and low insertion / extraction forces, and are ideally suited for low and high-current applications.

Advanced Contact Technology

Our advanced contact technology, the Multilam, meets virtually unlimited requirements, even within the most severe constraints, whether electrical, thermal or mechanical in nature. The Multilam is a multi-functional contact interface, which provides electrical performance coupled with mechanical properties. Its unique design allows constant spring pressure, so that during continuous or even permanent load, contact resistance stays low and voltage drop is minimal. The highly versatile Multilam is characterised by high energy efficiency, reliability and a long lifespan.

Your Solutions Provider

We offer various contact forms depending on your applications. Our cylindrical contact forms work for either a socket (to mate with a rigid pin) or a pin (to mate with a rigid socket). Our flat contacts are suitable for connecting busbars, either by pushing together or by clamping. Large busbar units can be connected with minimum time and effort. Our fork contacts are particularly suited for contacting busbars in slide-in technology. It is simple to install parallel busbars with flat-mounted fork plugs.

Our round connectors tolerate angular misalignments, so allowances can be made for axial displacements. Our combined contacts found in our CombiTac product line feature a modular plug connector system, which combines electric, gas, compressed air, fiber-optic, fluid, coaxial and thermocouple connectors in a single plug. We also offer multi-pole contacts, which allow for space-saving compact plug forms, especially suited for automation environments.

Industrial connectors

Our high-performance industrial connectors are designed to meet the demands of harsh industrial environments. Equipped with our tried and tested Multilam, they offer the lowest contact resistance and extremely high current density. Our power connectors are used in a wide range of applications, such as power generation and distribution, rack and panel applications, machine control systems, mobile transformers and many more. Wherever high currents need to be safely transmitted through a removable electrical connection, MC industrial connectors are the preferred choice worldwide. Product groups include:

  • Powerline: industrial power connectors for high current applications
  • Slideinline: slide-in rack connectors and fork plugs for bus bars
  • CombiTacline: modular connector system for plug-in module technology
  • Motorline: quick-connection adapters for electrical motor testing
  • Miniline: miniature connectors for printed circuits (PCB) and connecting leads
  • Utilitiesline: flat bar clamps and test accessories for electric utilities
  • Railwayline: electrical contacts for railway technology

Connectors for automation systems

Applications include manually or automatically actuated multi-couplings for docking systems, automated assembly lines, tool change systems for machining and moulding equipment, and robotics.

Our automatic system connectors feature a rugged and reliable design specifically engineered for high mating frequencies. They're equipped with MC Multilam technology for the lowest contact resistance and extremely high current density. Product groups include:

  • Dockingline: multi-pole connectors for multi-couplings and docking systems
