GF125-24ASCB-D 125 OHM DATA BUS CABLE

INNOVATIVELY DESIGNED DATA BUS The GF125-24ASCB-D is a laser wire markable, aerospace-grade Data Bus cable designed for use with Honeywell ASCB Data Bus and Servo CAN Bus for the Primus EPIC/APEX integrated avionics system. The GF125-24ASCB-D is a 125 ohm Twinax, which means the insulation thickness is increased to achieve 125 ohms between the conductors. The increased thickness creates an issue with contact extraction because the insulation OD is larger than the contact. With GIGAFLIGHT’s Data Bus, we have solved this issue by using a dual-wall insulation design. The first layer of insulation is a thinner wall high temp PFA with a finished diameter less than the contact OD. The second layer of insulation is a foamed FEP that provides the separation between the wires to maintain a 125 ohms-controlled impedance throughout. A section of the foamed insulation is removed in the termination process to provide access for contact removal. An added benefit of a dual-wall construction is that the solid insulation eliminates insulation creep back, a common issue with an all foam insulation design.
