The GIGAFLIGHT aerospace-grade, GF120T-24CANB CAN-Bus cable is approved by Garmin for use with their CAN-Bus System architecture. The white Tefzel CAN-Bus cable is laser-markable and designed to be a 120 ohm twinax, which means the insulation thickness is increased to achieve 120 ohm between the conductors.
The increased thickness creates an issue with contact extraction because the insulation OD is larger than the contact. GIGAFLIGHT has 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 120 ohm-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. The woven strip braid provides superior shielding effectiveness and enhanced insertion loss. The high-temperature CAN-Bus cable meets FAA flammability requirements, is lightweight and features low signal loss.
