If you work throughout the aerospace and defense industry then you know we are referring to the popular radio frequency cable, MIL-DTL-17/176-00002. The twinax data bus cable is one of WireMasters top selling and stocking items. With approximately 145,000+ feet in-stock WireMasters can ship this material the same day your order is placed!
Rated with an impedance of 77 ohms, the cable is constructed with two 24 gauge inner conductors, each consisting of 19 strands of 36-gauge silver-coated, high strength copper alloy wire. There is also two PTFE (Solid Polytetrafluoroethylene) dielectric cores twisted together with a left-hand lay with 11 to 14 twists per foot. Covering the PTFE dielectrics is a single layer of 38-gauge braid composed of silver-coated, high strength copper alloy wire. The cable is then finished with an extruded PFA (Perfluoroalkoxy) translucent blue jacket.
Weighing 18 pounds per 1,000 feet, the cable can also withstand up to 1000 volts holding nominal capacitance of 24.0 pf per foot. With a 68 percent velocity of propagation, the M17/176-00002 cable is useful in high-temperature applications withstanding operating temperatures of -55° to +200°C. The cable is often utilized in 1 MHz multiplex applications in accordance with MIL-STD-1553, which is a standard for a data-transmission method for avionics, seemingly in military applications.
With electronic applications and In-flight Entertainment (IFE) systems on the rise, it’s important for aerospace and defense engineers too incorporate quality wiring products like the MIL-DTL-17/176-00002 cable specification on their military vehicles, commercial and RF communications systems for enhanced signal transmission rates.
