The M-Max ATR-compliant chassis is a fully sealed rugged enclosures family with passive cooling, providing extreme physical protection for high performance systems. The machine-worked aluminum chassis is especially designed for the most challenging environments. The ATR-compliant enclosure excels in critical applications needing to operate under extreme temperatures, dust and humidity. Providing excellent shock and vibration protection, the completely fanless chassis uses natural convection and conduction cooling. Typical systems housed in this ATR-compliant enclosure deliver IP66 dust and moisture protection, withstand shocks up to 40g and vibration up to 2.5g. The fully sealed 1/2 ATR Short version enclosure houses up to 8 PC/104 or similar sized boards. The configurable front panel can be outfitted with variety of customer-defined connectors.

MicroMax, as a manufacturer of ruggedized industrial computers, takes a customized approach to each client. Our engineering group can design M-Max systems to fit customer-specific technical requirements.
