What is VPX used for?
VPX, also known as VITA 46, is a set of standards for connecting components of a computer (known as a computer bus), commonly used by defense contractors. VPX, based on the VITA 46 and VITA 65 OpenVPX standards, is a widely adopted high-speed interconnect system used in defense, aerospace, and rugged embedded environments. It supports both 3U and 6U form factors and enables system modularity through backplane-based configurations with traditional card edge connections.OpenVPX is a system standard for VPX that provides a defined architectural framework for interoperability between OpenVPX products. OpenVPX leverages the VPX dot specs for details such as fabric protocols.The VPX power supplies are compliant with VITA 62, MIL-STD-704, MIL-STD-461 and MIL-STD-810 for 28 Vdc, 270 Vdc and AC-DC systems. The VPX delivers up to 1000 W and up to 6 outputs with a typical high efficiency of 91%.
What does VPX stand for?
VPX, or VITA Portable eXtended, is a standardised framework for electronic modules and backplanes designed to operate in demanding environments. It outlines specifications for board dimensions, power delivery, and signal connections, ensuring compatibility between components from different manufacturers. Unveiled in the early 1980s, the bus was intended to be a flexible environment, capable of supporting a variety of computing-intensive tasks. Yet despite the development of other standards – such as VPX – VME has not only survived but continues to see new products being developed.VPX, or VITA Portable eXtended, is a standardised framework for electronic modules and backplanes designed to operate in demanding environments.

What is VPX technology?
VPX technology, also known as VITA 46, is a set of standards for connecting components of a system. It is commonly used by defense contractors and integrators, providing a robust and reliable solution for applications in hostile environments that require high speed I/O. VITA 48 is essentially a mechanical standard that provides yet another level of capability above the VITA 46 standard. It uses the same connectors as defined in VITA 46 and provides all the same bandwidth and user I/O benefits.
What are the advantages of using VPX?
Suitable for use in rugged environments, VPX is ideal for military and aerospace applications where systems need to be able to withstand harsh conditions, like shock, vibration and extreme temperatures. Effective thermal management is critical to unlocking the full performance of VPX systems—safely, reliably, and consistently. In advanced ground vehicles and aircraft, self-contained liquid cooling offers optimal thermal management, delivering superior reliability and performance over traditional air cooling.
