Connector housings are molded from self-extinguishing black thermoplastic material for high impact and dielectric strength. O Termination wire range. Terminations are insul
6、ation displacement type which accommodate .O50 inch (1.27 mm) centerline flat cable conductor with wire ranges of 26-30 AWG solid or 28 AWG stranded wire. Contact rating. Termination resistance. Contacts shall be rated at 1 ampere maximum at +25OC. The contact resistance shall be 22 milliohms maximu
7、m initial for mated connectors and 12 milliohms initial for unmated connectors. Dielectric withstandinq voltage. There shall be no breakdown of the insulating material when subjected to 1000 V ac for 1 minute between adjacent contacts of the mated connector assemblies. Mating force. Unmating force.
8、Durability. Connector mating force shall not exceed 3.12 newtons (0.7 pound) maximum per contact. Connector unmating force shall not exceed 0.89 newton (0.20 pound) minimum per contact. Durability shall consist of 200 cycles of mating and unmating and upon completion the termination resistance shall
