These connectors can go through about 10,000 mate/unmate cycles without a loss in performance, can be mated and unmated in less than two seconds, and offer less crosstalk with the contact in the female connector mating directly with the PCB on the plug half. The connectors use 34-way high-density contact modules, and a simple cam and bearing mechanism allows all the contacts to be mated at once with a quarter turn of the knob shaft. Mating torque is 2 N.m, and shock and vibration performance is to MIL-STD-202F. They come in 136, 204, 272, and 408 configurations. They have a maximum contact resistance of 30m and a rated current of 0.5A. Metal shells and grounding springs offer plenty of EMI/RFI protection. They cost about $0.30/IO depending on volume and configuration.
