Today, some customer applications have requirements for high bandwidth transfer between VMEbus cards. Requirements whicheven the most updated VME parallel bus cannot support. To meet this need the VITA 41 specification has been developed. VITA 41
VXS (VME Switched Serial) defines a common data plane interconnect using switched serial topologies.
Positronic’s VPX power connector was developed to support VITA 41. The VPX series provides a dedicated power interface
between boards and backplanes eliminating the need to use valuable high speed contacts to carry power.
The VPX series has a unique package size which allows compatibility with conduction cooled boards per IEEE 1101.2.
A unique size, multiple power contacts, three levels of sequential mating and high reliability make the VPX series suitable for VITA 41
or any similar application.
