Maximum protection for short RS-232 runs in noisy environments. Quick Facts - Protect your data from end to end with a 100% foil shield plus an 85% tinned copper-braided shield. - Ideal for industrial environments. EMI/RFI-resistant hoods stop damaging noise where cables are most vulnerable—at the connection. - Remove the metallic, EMI/RFI hoods for convenient testing or repinning. - Guaranteed for life! Further Details - In extra-noisy environments, they're made for the short - run—up to 50 feet (15.2 m). - In extra-quiet environments, use these cables for long runs—up to 500 feet (152.4 m). - 24-AWG stranded copper conductors. - Die-cast, removable a DB25 connector. - 25 conductors (12-1/2 pairs), pins 1–25. - NEC CL2.
