Belden Inc. Security & Sound, #20-4c, BC, Shielded, CMR 5402FE

The 5402FE Security & Sound Cable from Belden Inc. features four 20 AWG stranded bare copper conductors, insulated with polypropylene and shielded with Beldfoil¬Æ for enhanced protection against interference. The cable is designed for riser applications and is suitable for use in security systems, intercoms, public address systems, audio/speaker setups, and power-limited controls, particularly in noisy environments. The cable has a nominal outer diameter of 0.163 inches (4.14 mm) and is encased in a PVC jacket with a ripcord for easy stripping. It operates within a temperature range of -20¬8C to +75¬8C and has a UL voltage rating of 300 V. The maximum current capacity is 6.4 Amps per conductor at 25¬8C, with a nominal conductor DCR of 10.2 Ohm per 1000 feet. The cable complies with various standards, including UL 1666 for riser applications and NEC Article 800 for communication cables. Engineers should consider this cable for projects requiring reliable performance in indoor riser installations where shielding and conductor quality are critical.
