Cabinets meet railway shock and vibration standards
Withstanding the high shock and vibration typically found in railway applications, Optima Stantron has designed and successfully tested cabinets to meet both North American (AREMA) and European (CENELEC) railway standards. Optima Stantron designed the welded and riveted frame by modifying the standard M1 cabinet frame design.
The cabinet had to meet a customer’s specific requirements for AREMA Part 11.5.1 Class I - Vehicle Interior (Platform-Mounted), which examines the operation of electronics inside locomotive spaces. Optima’s cabinet did not require shock isolators in order to meet the mechanical shock and vibration requirements mandated by the railway industry.
The cabinet design was required to conform to CENELEC EN 61373 Class 1A, specifically targeted at sub-assemblies and equipment mounted on or under a railway car, as well as AREMA Part 11.5.1 Class I, which tests several physical characteristics of electronic equipment mounted in the enclosed interior space of the locomotive.
Ron Hall, Director, Cabinets Product Line, Optima Stantron, comments: “Optima is very familiar with meeting tough environmental requirements due to our experience in defence applications. We met our customer’s challenge and delivered a robust cabinet that they can rely on to protect the sensitive electronics in their rail equipment.”
