VITA Specifications – VPX Compliance

 VITA Industry Standards
 Vita 46/48 Specification compliance requires full inter-matability with
current Vita 46 connector platform
 VIPER connector meets aspects of Vita 46, except inter-matability.
 New Vita 60 Specification is in progress
 VIPER can be mounted in the same backplane and daughtercard
hole pattern as Vita 46

 “VPX” industry name is trademarked by VITA
 VIPER is a compatible PX connector designed for extreme
environments
