Belden 82841 877, Multi Conductor Computer P.O.S. Cable 1 Pair 24 AWG
Description
Belden 82841 877 is a 1 pair 24 AWG RS-485 and computer/P.O.S. communications cable with a PVC outer jacket and CMP plenum rating for indoor installations. It uses 24 AWG (7x32) TC - Tinned Copper conductors with FEP - Fluorinated Ethylene Propylene (Foam) insulation. For noise-sensitive runs, it includes an overall Beldfoil® shield plus a 90% tinned copper braid. Electrical performance includes 120 Ohm nominal characteristic impedence and UL Voltage Rating: 300 V (CMP).
Belden 82841 877 Key Features
