The NI PR27-30F Cable (1 Meter) is a shielded industrial fieldbus cable engineered for process control, petrochemical, and subsurface applications. Dual-screened twisted-pair construction with tinned copper conductors, individual pair shielding, and comprehensive outer protection deliver exceptional EMI rejection and signal integrity in harsh environments. 300 V nominal rating with flame-retardant or LSZH jacketing options supports installation in cable trays, conduits, buried ducts, and hydrocarbon-rich settings.
