1½ ATR Long ATX Chassis

Macrolink’s ML-1500 Series Seahawk is a convection-cooled  very rugger PC chassis to house numerous ATX type motherboards and GPUs. This robust chassis is designed for avionics and ground vehicle applications. The structure is capable of withstanding extreme environmental conditions of altitude, temperature, humidity, shock, vibration, EMI, and chemical exposure.

ML-1500 Series ATX Convection Cooled Electronic Equipment Enclosure

  • Drawing on decades of design and field deployment experience, the Seahawk is crafted to provide outstanding configuration flexibility, long life, and dependable service.

    • Aggressive package
    • Additional power for external drive systems
    • MIL-STD-1553, video, RS-429 and other combinations available
  • A blend of machined, formed, and extruded components impart an exceptional degree of structural integrity, while significantly reducing the number of mechanical fasteners for increased reliability and ease of access to Field Replaceable Units. System boards and peripherals are easily accessed through the removable top cover. Covers contain captive hardware and metal braided EMI gaskets. All internal and external surfaces are coated with an exterior epoxy finish providing maximum protection against corrosion. All materials and finishes are fungus resistant.Seahawk_3D_350
  • The integral front panel accommodates MIL style M38999 connectors along with high-density COTS components and is customized to meet each application’s requirements. Internal cables connect the front panel to the motherboard’s back panel I/O connectors, and the expansion slot board I/O connectors.
  • Oversized, filtered, air intake and baffling combined with high-efficiency fans insures generous airflow through the card cage and peripheral bay. A sophisticated thermal management option extends the development capability to operating environments reaching -20ºC ambient.
