Rugged, Innovative ATR Enclosure Designs

Eletter Product

CAP003994-rugged-cc-vpx-chassis-angledElma's full line of convection, conduction and liquid cooled ATR enclosures support a wide range of rugged airborne and mobile deployed applications. Our modular, COTS system platforms offer standardized, cost effective solutions for VME, VME64x, cPCI, VXS, VPX and Small Form Factor (SFF) based applications. Available in 1/4, 1/2, 3/4, 1 and 1 1/2 ATR tall long formats per ARINC 404A, ARINC 600 specifications, the modular design CAP004377-angled-rightconcept allows for a wide range of customization options without the cost and lead-time penalties associated with traditional construction techniques. All aluminum or Al-composite ATRs are designed to optimize weight while maximizing cooling and payload considerations.  Removable I/O panels allow for customization to exact application requirements and increased configurability.  ATR enclosures use electrostatic dust filters, honeycomb EMI filters and EMI gasketing techniques to ensure compliance to MIL-STD-461E EMC requirements.
