Smiths Connectors has launched a new Transformer Connector Range. The family of high-density modular connectors provides customers with an enhanced ability to tailor interconnect solutions to the demands and requirements of their individual application environments. The connectors target rail applications where extreme pressure is placed on connector technology manufacturers to fulfill critical rail-specific performance challenges of reliability, safety, maintenance and modularity in addition to standard compliance, plus meeting stringent electrical and environmental requirements.

The design of the Transformer range includes a number of innovative features including multiple configurations possible using the same piece parts, cost savings in working capital with local customer assembly and the flexibility to integrate local content for components and cabling

The parts modularity enables customers to design their own solution by supplying the elementary components of the whole connector. It employs a unique do-it-yourself system based on the building block principle. It has been customised for applications requiring the transmission of very high currents such as power distribution, inter-coaches and bogieswhile guaranteeing the highest level of safety for the passenger.

The connectors also use the Smiths Connectors’ HPC (High Power Contact) technology, a spring-shaped contact made of aluminum or copper that allows for more contact points to reduce overheating and to achieve low mating force during the connection. This contact technology design meets the trend to increase energy level on electrical and electronic equipment for managing higher current ratings.

The Transformer range is available in 2, 3 and 5 pole versions; supporting up to 700A per pole and a voltage rating of 3600V. The connectors are easy to assemble and use due to the incorporation of just three contacts, and cross section cables can be covered from 25mm² to 350 mm². No specific tool is required, with consequent reduction of supply chain, maintenance and cabling costs.

Made with a plastic insulator and aluminum frame the Transformer optimises against ballast and enables weight savings contributing to reduced energy consumption. The materials used ensure compliance with fire and smoke standards, according to NF F 16-101 & NF F 16-102 and EN 45545.

“Through interconnect innovation Smiths Connectors has designed a rugged, reliable and high-performance modular solution for rail transportation applications, but also for hybrid and electric vehicles and various other industries.” said Gabriel Guglielmi, Smiths Connectors Vice President of Business Development and Strategy.
