The 1503A-RED-U1000 is part of Belden's line of bonded-pair cables, designed to reduce or eliminate crosstalk, skew, impedance mismatches, and other installation errors caused by untwisting and separating pairs of signal-carrying wires within a cable. The 1503A-RED-U1000 is an unshielded, PVC-jacketed, 23 AWG cable with 4-pair twisted, bonded-pair construction and solid BC conductors. The flame retardant cable is riser-rated, with an operating temperature range of 0°C to +60°C, CMP and cULus, and ETL verified. The U1000 PVC jacket has a low coefficient of friction and excellent abrasion resistance, making it well suited for general purpose wiring in commercial and residential applications.
