J-Type Connectors Dura Con / Cinch J-Type Connectors offer a 5A current rating, 5mΩ contact resistance, and 250 mating cycles. J-Type Connectors feature 12 finger socket resilient contacts that engage with each flat plug pin to provide low contact resistance, high current carrying capacity, and minimum insertion and withdrawal forces. These connectors are available in 4, 8, 12, and 20 connector sizes. Dura Con / Cinch J-Type Connectors are used mainly in industrial applications where heavy impact forces are expected.
