Cable Construction & Specifications

DynaFlex® 100 Series cables offer an optional polyurethane jacket for excellent UV resistance in outdoor installations or for low smoke, halogen free jacket requirements. Solid center conductors contribute to better attenuation performance and are best suited for applications requiring less than 10,000 flexures. (For Applications requiring Higher Flexure Life see Series 400)

Power, Attenuation & Phase Characteristics

To determine the maximum power rating of a cable assembly at ambient conditions, compare the average power rating of the cable against the connector average power rating (see page 13) and take the lowest value.

Power handling is specified for ambient conditions at sea level and +25 degree C. Use the de-rating chart (shown below) to estimate average or peak power levels at other altitude or temperature conditions.
