Smooth contact surface
The specification for the AdvancedMCTM entails 200 mating cycles for a module. The nickel/hard gold layer on the relatively soft copper can only stand up to this high load if the contact surface is absolutely smooth.
This is the case with the con:card+ connector. With years of experience in stamping techniques and the utilization of high-performance stamping tools with special process components, HARTING and ept are actively involved in minimizing gold pad wear.
