Innovative I/O Solutions in Rugged ATRs

Eletter Product

Elma's full line of field-proven convection, conduction and liquid cooled ATR enclosures support a wide range of rugged airborne and mobile deployed applications.

Innovative I/O Solutions in Rugged ATRsOur modular, COTS system platforms offer standardized, cost-effective solutions for open standards-based board sets (OpenVPX, SOSA™, VME). 

Available in 1/4, 1/2, 3/4, 1 and 1 1/2 ATR to ARINC 404A & 600 specifications, our modular design concept allows for ample customization options without the typical cost and lead-time penalties.  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.
