ALSTOM selects SMS Flame Retardant connectors


SMS Flame Retardant is a range of lightweight rectangular plastic connectors for railway applications, which provide excellent levels of resistance to fire and smoke. They are the only connectors in their category to be certified for onboard uses in accordance with requirements II / I3F2 of standard NF F 16-101/16-102.

The latest addition to the Souriau SMS series of railway connectors uses a UL94V0 thermoplastic that enables it to stand up to fire and smoke. It is designed for onboard railway applications: connections in passenger compartments, drivers’ cabs, lighting, control consoles, etc. SMS Flame Retardant connectors are made in two versions, with or without a cover, and both versions are available with 10 arrangements and up to 36 contacts. They feature the crimp fastening contacts in the Souriau TRIM TRIO® AWG16 range.

Their highly compact design makes them ideal connectors for integrations in locations with little space and for high-density applications. For example, they measure just 8 x 11 mm in the two-contact AWG16 arrangement and 23 x 46 mm in the 36-contact AWG16 arrangement. SMS Flame Retardant connectors feature the quick locking and release clip system found in the SMS series. They are designed to stand up to 500 locking/release cycles and they are particularly well suited to harsh environments, with temperatures of use ranging from –40°C to +105°C.

SMS Flame Retardant connectors are part of the TRIM TRIO® family. This is a very wideranging family, the only one of its kind on the market, designed around a single modular base. The sockets are common to all the TRIM TRIO® connectors. That means of course that the contacts are also the same. Thanks to its modularity, the breadth of its range and its very high levels of resistance to harsh environments, the TRIM TRIO® family is a yardstick for industrial connections. SMS Flame Retardant connectors have only been on the market for a few months, but they already equip the Citadis trams and the Metropolis metro cars made by Alstom. They will be presented at the Innotrans show in Berlin, from 23 to 26 September 2008.
