Samtec proudly supports the release of the new ANSI/VITA 74.0-2017 Small Form Factor Base Standard. VITA 74, also referred to as VNX, defines both the mechanical and electrical standards necessary for a small form factor (SFF) system.

Designed for deployment in rugged environments, VNX systems provide rapid serial fabric interconnects in a plug-in module format. These systems also feature improved size, weight, and power (SWaP) characteristics, crucial in an embedded system.

Samtec’s SEARAY™ right-angle connectors are featured in the VITA 74 base standard, which specifies 12.5 mm and 19 mm stack height plug-in modules. SEARAY™ right-angle is capable of speeds up to 25 Gbps, provides low insertion/extraction forces, and also features solder charge terminations. This connector was chosen based on its successful performance in the VITA 57.1 FMC Standard, as well as its high-speed capabilities and rugged design.

“The release of the ANSI/VITA 74 VNX Standard provides system designers with the ability to extend proven VPX technology into smaller form factor systems,” said David Givens, Standards Director. “Through the use of the proven Samtec SEARAY™ connectors, the Standard supports current generation rapid serial fabric interconnects such as 3rd Generation PCI Express®. Given the outstanding SEARAY™ performance, the Standard is ideally positioned to support future generation fabrics as they become entrenched in the rugged embedded system marketplace.”
