The 2000 Series consists of a portfolio of embedded computer product reference designs suited for all standard board form factors on the market today. The Class 2000 consist of fan-cooled enclosures while the Class 2100 consist of sealed, conduction cooled enclosures. Both Classes support highly rugged and MIL spec applications required by the defense/aerospace markets as well as commercial/industrial applications such as railway, public safety/first responder vehicles and outdoor installations requiring a waterproof design.

Two classes of product are provided and are classified by the type of cooling technology utilized. A variety of standard products exist that can be further customized.

Class 2000
Convection Cooled Rugged Embedded Computers

  • Machined aluminum (aerospace grade 6061-T6) housing with formed sheet metal (aluminum 5032-H32) internal structures and brackets

  • When a traditional ATR is not the perfect fit, the Model 2170 can be selected to house single or multiple boards with or with a backplane. All Eurocard backplanes and boards supported:
    • CompactPCI (cPCI)
    • VME and VME64x (ANSI/VITA 1.1-1997)
    • VXS (ANSI/VITA 41)
    • VPX (VITA 46), OpenVPX (VITA 65) and VPX REDI (VITA 48)
    • Hybrid, custom and semi-custom configurations designed and fabricated in house.
  • Custom I/O panels can be discretely wired or a PCB can be designed to plug into the host board.

An “empty” enclosure can be provided for any model or select the Model 2100 which is specifically designed for prototyping
