These connectors offer wide versatility in insert arrangements for not only concentric twinax contacts, but also coax, triax, PCB, wire wrap, thermocouples and EMI filter contacts. The size 8 concentric twinax contact was developed for use in MIL-STD-1553 Airborn multiplex data bus applications, which require high performance, interconnect characteristics in multi-pin connectors. Ideal for this application need is the high performance Tri-Start connector with its fully scoop-proof feature of recessed pins. The concentric twinax contact is crimp terminable to twisted shielded cable.
