Off-the-shelf sub-rack meets railway standards

18 June 2003 Manufacturing / Production Technology, Hardware & Services

The Type 12 off-the-shelf sub-rack family from Elma has recently passed the demanding BN411002 and BN411003 mechanical and environmental tests of the Federal German Railway. As well as underlining the reliability of the standard Type 12 sub-rack for a wide range of rugged applications, this approval gives designers a secure and low-cost route to housing single or double Eurocard electronics for railway applications.

The Type 12 is available in a range of heights from 2U to 9U, with or without advanced EMC features, handles, slide rails or covers. In addition to an extensive range of accessories and cabinets, Elma also offers a configuration and customisation service to shorten system build times by delivering sub-rack assemblies complete with backplane, PSUs, fans, CD and disk housings.

The German railway tests include the EMC version (Type 12), and cover cyclic moist heat to +55°C and cold to -40°C (EN60068), with salt spray to EN50155. Mechanical testing (EN60068) included 'resonance search' vibration testing, and positive and negative shock testing. Because the standard Elma Type 12 passed all these railway industry tests first time, Elma believes that this versatile family can provide an off-the-shelf solution for a number of other industry-specific applications in particularly tough environmental requirements, and encourages customers to ask about such needs.

Local application engineers are available to offer advice and guidance on the capabilities of the Type 12 family, backed by Elma's proven capabilities to develop customised solutions for the toughest requirements in equipment housings and sub-racks.
