About 50 ohm cable assemblies

This cable assembly has a characteristic impedance of 50 ohms. 50 ohm coax cable, connectors, and adapters are commonly used in GPS and wifi (802.11 wireless LAN) antennas, ham transceivers, and other radio frequency (RF) analog and digital signaling, microwave, radar, hi-fidelity professional audio, non-destructive testing (NDT), oil and petroleum production, ultrasonic transducers, accelerometers, strain gauges, and some professional video applications.

About Low Noise Cable

This is a "low noise" cable, with a carbon-impregnated conductive PTFE layer added around the PTFE dielectric; this layer helps to increase shielding, dissipate static charge, and reduce mechanically-generated electrical noise as the cable is flexed. This extra protection is useful for long cable runs, low-voltage signals, high-vibration environments, in applications including aerospace, automotive, NDT, strain gauges and accelerometers, and extremely high fidelity professional audio production.

Low noise cable is generally not recommended for RF use. In our own testing, we see characteristics which differ from ordinary cable, including phase delay and impedance variations with frequency. In the field, we've seen mixed results in the GHz range; low noise cables seem to provide the best results at signal frequencies in the low MHz or lower. Ultrasonic NDT, for example, uses low-noise cable with signals as high as 100 MHz, but in transient pulse trains, where phase delay is less critical. The results you get will depend on the application, and as always you will want to do your own testing before ordering large quantities.

We hi-pot test our cable assemblies for high-voltage breakdown between core and braid. See About Hi-Pot Testing for why this might matter to you, particularly for physics or NDT applications. Caution: We make no claims as to the safety of this product for high-voltage use. These voltages can kill. Do not handle or approach any cable or conductor carrying high voltage; this includes insulated cables, nearby metal parts, water, and other conductive materials. Engineering and design for safety in your application are your responsibility.
