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, medical, 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 any 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 pulsed loads, contact resistance stays low and voltage drop is minimal. The highly versatile MULTILAM is characterised by high energy efficiency, reliability and a long lifespan.

The MC Multilam, our advanced contact technology, present in all of our connectors, offers unlimited design flexibility for your applications and ensures a safe, reliable and long-lasting connection.
Our battery cable connector ensures safe and fast connection of batteries for stationary or mobile applications. Excellent for renewable energy storage during peak times.
The CombiTac modular connector system allows for individual combination of power, signal, thermocouple, coaxial, pneumatic, hydraulic and bus applications in a space saving compact frame.
21-BV high power connectors for mobile applications are able to withstand harsh environments, such as in offshore technology applications.
Multi-Contact offers complete junction box and connector solutions for the renewable energies market, featuring the original industry-standard connector system MC4.
The modular power connector is a universal multi-application solution for the railway industry, featuring a compact and modular design able to carry out electrical connections in railway rolling stock.
Our multi coupling system combines power, fluid and signal connections in a compact design. MCS are typically used for high-performance applications demanding high reliability and repeatability.
For direct connection to copper or aluminum bus bars, our standard GSR fork connectors are suitable for applications in non-corrosive environments indoors or protected outdoor installations.
Safety flat bar clamps for rapid and safe contact of busbars in power distribution plants, power generation units, mobile transformers and standby power packs.

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 rack and panel applications. 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 contacts found in our CombiTac product line feature a modular plug connector system, which combines electrical signal, power, gas, compressed air, fluid, fibre-optic, communication, coaxial, and thermocouple circuits in a single connector. We also offer multi-pole contacts, which allow for space-saving compact plug forms, especially suited for high mating cycle applications such as 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, 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
