Subracks can sometimes be subjected to a wide variety of demands in terms of mechanical stability in certain applications ̶ shock and vibration resistance for example.
Pentair has addressed this challenge by offering Schroff subracks for shock and vibration requirements between 5 and 25g as part of its standard product portfolio. These subracks are designed for use in fields such as transport, railway, industrial (eg, close to rotating machines), power stations, and defence technology.
Pentair’s Schroff branded subracks product line is compliant with all applicable industry standards. For rail technology, these include the European standards IEC 61587-2 and EN 50155 Part 12.2.11, NFF 67012 and NFF 60002 for French railways, as well as BN 411002 and BN 411003 for the German rail system. Furthermore, the subracks are certified in accordance with MIL 167, MIL 810G, MIL 901D, and IEC 61587-2 (degree of severity DL3) for use in defence technology and applications.
All Pentair subracks for enhanced shock and vibration requirements feature self-locking fixing screws, special rounded corners and edges (eg, on the 19-in brackets) and an additional top cover, locking for access protection. This also ensures that safety and sound insulation requirements are fulfilled. Additionally, the subracks can be equipped with guide rails for conduction-cooled assemblies.
In addition, many applications require an extended temperature range from -40°C to +85°C. Pentair is one of the first in the market to offer its worldwide customers an EMC (electromagnetically compatible) textile gasket that is resistant to such high temperatures. Historically, stainless-steel gasketing has been used for EMC shielding requirements in high temperature applications. Compared to stainless-steel gaskets, textile gaskets are considerably cheaper and easier to use.
With designers and hardware developers in mind, the 3D CAD data for the subracks can be downloaded from the TraceParts online platform free of charge. Customers are able to access 32 different native CAD data formats, which can then be used directly in their own CAD application. If the user does not have a CAD system or CAD viewer, 3D perspectives of the products can also be downloaded as PDF files, either for user documentation or simply for visual reference.
