Elma Electronic Inc. has a long history of delivering rugged embedded computing subsystems for mission critical equipment in some of the most demanding defense programs across the world. Elma designs and builds precision, high-speed backplanes, rugged electronics enclosures, hardware and subsystems assemblies following a modular open systems approach (MOSA) and using open architectures such as SOSA™, CMOSS and OpenVPX. Our hardware is used in C5ISR, EW, SIGINT, and sensor-based defense applications.

Participating in open standards organizations like SOSA™ and VITA enable us to quickly deliver agile embedded solutions. Our 901D/810E cabinets are unrivaled and trusted to protect equipment in the harshest environments.

We maintain multi-decades-long relationships with our customers by consistently delivering highly reliable embedded systems solutions for use in land, air and sea defense platforms. Our customers deliver platforms used in C5ISR, SIGINT, EW and sensor-based defense applications.
