Description
Belden 82503 877 is a 3-pair, 24 AWG computer EIA RS-232 cable designed for reliable signal transmission in indoor plenum environments. It features 24 AWG stranded (7x32) tinned copper conductors with FEP insulation, plus an overall Beldfoil® shield (100% coverage) and a 24 AWG stranded tinned copper drain wire to help reduce noise. The Flamarrest® jacket and CMP plenum rating support use in demanding building spaces where fire performance is critical.
Belden 82503 877 Key Features
- 3-pair, 24 AWG computer EIA RS-232 cable construction for signal transmission in indoor plenum environments.
