Weidmuller is now one of the industry's leading international providers of connectors. An important mainstay in this product family are the circular connectors, which Weidmuller groups under the product name SAI. In the development of SAI products, Weidmuller engineers have always concentrated on achieving rational, cost-effective installation concepts, and - in cooperation with major users - have supplied the markets with well-conceived products which set standards in terms of functionality and quality across the globe. The best examples are the new power distributors with S and T coded M12. These modules are characterised by particularly high currents and voltages. This enables them to also be used, for example, with three-phase motors.
