System Platforms
Elma has one of the most extensive and impressive offerings of Rugged COTS System Platforms . With an extrusion-based modular design, customization is easy and cost-effective. The COTS 12R series is a high quality rugged package for all VME/VME64x, VXS, VPX, CompactPCI and CompactPCI Express applications. The rugged product line includes 2U-14U models for both 6U and 9U cards. Intended to withstand the demands of a military environments, the 12R series is designed to meet benchmark military standards. To comply with MIL-STD-461D, the 12R platform uses electrostatic dust filters, honeycomb EMI filters, braided gasketing, and metal impregnated flat gaskets to seal off every external opening and seam. The rugged designs meet the requirements for shock and vibration according to MIL-STD-167, MIL-STD-810F and MIL-STD-910D. Test reports and performance specifications are available upon request. All 12Rs are compliant to IEEE 1101.1/.10/.11 mechanical specifications and IEEE 1101.2 for conduction cooled applications and can accept up to 20 boards. The 12R series are built from aluminum sheets and extrusions. The parts are joint together by spot-welding, riveting and stainless steel screws. All removable covers are equipped with captive screws. Furthermore, the 12R series are equipped with MIL-grade components, system monitoring LEDs, powerful cooling systems, and are available with fix mounted or shock isolated card cages and drive bays.


Cabinet Enclosures & Consoles
Elma also specializes in Mil/Aero rugged cabinet enclosure designs through our Optima EPS division. The Optima M series MILSPEC Cabinet System is a unique modular construction designed to exceed military standards and can adapt to the equipment-mounting and protection needs of virtually any electronic system. It can accommodate customer specific requirements for: EMC shielding, shock and vibration, mobility, thermal management, power distribution/conditioning and I/O cabling per the application MIL-STD’s. Because custom designs are based on proven design concepts the cost, schedule and performance risks are substantially reduced.

Optima also provides desk systems and consoles for defense applications. The designs feature shock mounting, EMI/RFI shielding, thicker gauge material and other ruggedization provisions.


Elma’s backplane division, Bustronic, is renowned for its high-performance designs for Mil/Aero applications. The company offers standard and custom architectures including VME/64x, cPCI, VXS, VPX, ATCA, MTCA and more. Design considerations are conformal coating for protection, stiffeners, and special power or shielding options.


Elma also offers various components for defense applications, including front panels, handles, switches, encoders, and LEDs. When it comes to mission-critical applications, Elma’s rugged reliable components are a must.
