The HARTING MicroTCA connectors meet all the requirements specified in the current version of the PICMG ‘Rugged MicroTCA’ subcommittee without contact interruptions. The key to the rugged performance of these connectors is a concept known as con:card+, which uses an innovative GuideSpring configuration to stabilise the connection against shock and vibration by offsetting any possible tolerance deviations and provide defined positioning.
As an alternative to the card edge and gold pads on the AdvancedMC card, HARTING has also developed a plug connector with manufacturing tolerances much lower than those of the PCB card edge. With this approach, contact interruptions that are based on the tolerance problems of the card edge are prevented from the outset.
