Thanks to a new double-fork connector from Stäubli Electrical Connectors GmbH, it has now become possible to connect two conductor rails simultaneously. The connector is mainly used in distribution and control cabinets with a current requirement of 100 up to several thousand amperes. With a high level of compensation for misalignment and a flexible design, it provides cost-effective solutions and allows adaptation to individual requirements. Being designed for up to 5,000 mating cycles, it minimises maintenance and replacement costs.

Be it for power supply, power electronics or storage technology, wherever busbars need to be connected, Stäubli’s MULTILAM contact technology ensures the lowest contact resistance and a very high current density, while maintaining a high and constant performance. The wide range of single-ended fork connectors and double-fork connectors for railway applications enables compact and powerful solutions for infrastructure and rolling stock applications.

For the electrical connection within the traction chain and for on-board power applications, such as traction converter and battery outputs or the connection between the car body and the engine, the Modular Power Connector MPC is used in a wide variety of rail vehicles. Modular and compact, it reliably transmits high voltages and currents.

The modular connector system CombiTac is used on the one hand as a powerful solution in battery packs and battery management systems, and on the other hand to feed traction motors with power. Thanks to its hybrid, individually configurable design, CombiTac is a compact solution for control and communication systems as well as for testing applications. Customised solutions which exactly fit the spatial and technical specifications, as well as ready-to-install package solutions including cable assembly, simplify the integration, save assembly costs and reduce the logistics effort.

Miniature to high-performance connectors

The international Stäubli Group, headquartered in Pfäffikon, Switzerland, stands for mechatronic solutions in the three core areas of connectors, robotics and textile. Stäubli employs more than 5,500 people worldwide, is present in 29 countries with production, sales and service subsidiaries and is complemented by representations in 50 countries.

In the field of connectors, Stäubli is the world market leader in the production of fast coupling systems for all types of fluids, gases and electrical energy.

The Electrical Connectors product portfolio (formerly Multi-Contact) ranges from miniature to high-performance connectors for power transmission, automation industry, transportation, test and measurement. In photovoltaics, Stäubli is the world market leader with its MC4 connector components. The MULTILAM technology is at the heart of its electrical connectors.
