1421A RS-232/422 Cable - 4 Pair Low Cap Shielded

The Belden 1421A provides four twisted pairs for RS-232/422 computer communication with low capacitance characteristics enabling longer cable runs and faster data rates. Each pair consists of 24 AWG stranded tinned copper conductors in a 7x32 construction optimized for data transmission.

Datalene® insulation delivers low capacitance properties that maintain signal integrity over extended distances. The 100 ohm impedance matches balanced digital transmission requirements for RS-422 applications where all four pairs carry data.

The overall Beldfoil® shield provides 100% coverage against electromagnetic interference, with a 24 AWG stranded tinned copper drain wire for reliable shield termination. The PVC outer jacket provides standard protection. CM rated for communications use, the 1421A serves computer equipment, data terminals, and facilities requiring four-pair low capacitance serial data cabling.
