I would be very concerned with the 5,000 mating cycles. Most of the connectors mentioned here don't have terminals that withstand that many cycles. Here is my recommendation from Amphenol. They have a terminal that can withstand over 10,000 mating cycles. In comparison, the Mini-ft Jr, even with Molex's special high-cycle terminal is only rated for 1,500 mating cycles. Let me know if you want more information.
