Elma Electronic Inc. has released a ruggedized ATR chassis for MicroTCA that passes military testing for shock/vibration and EMI requirements. The MicroTCA chassis is an ARINC 404A full-size ATR long enclosure, often used in commercial and military aviation.

The rugged enclosure features modified front panels that can be secured to the chassis. This provides more protection for shock and vibration. Shock absorbers/dampers can also be added to the enclosure for extra protection. Thermal management can be achieved via either convection or conduction-cooling.

Testing shows the chassis meets the MIL-STD-810E shock/vibration requirements and MIL-STD-461 for EMI. The vibration and shock tests were performed according to the IEC 61587 1 and VITA 47 standards in six axes (three spatial axes, with the system rotated by 180 for each axis). A full 30-page test report is available on request.

The backplane holds six AMCs, one MCH (MicroTCA Carrier Hub), and one power module. Single module slots in the full size are standard, but other configurations are possible due to the enclosure's modular design.

Pricing less than $12,000 for the base configuration and depending on volume. Since the MicroTCA.1 and MicroTCA.2 specifications for rugged MicroTCA are still in draft, Elma offers the MicroTCA ATR for early development/testing until these specifications are completed.
