Belden 82729 877, Multi Conductor Snake Cable 2 Pair 24 AWG FFEPR
Description
Belden 82729 877 is a 2-pair, 24 AWG stranded (7x32) TC - tinned copper cable designed for computer EIA RS-232/422 and digital audio signal transmission. Each pair uses FEP - Fluorinated Ethylene Propylene (Foam) insulation and is individually shielded with Beldfoil® (100% coverage) plus a 24 AWG (7x32) TC drain wire to support noise rejection. It features a Flamarrest® plenum-rated jacket for Indoor - Plenum installations and carries a UL voltage rating of 300 V (CMP).
Belden 82729 877 Key Features
- 2-pair construction with 24 AWG stranded (7x32) TC - tinned copper conductors for signal transmission.
- Individually shielded pairs using Beldfoil® tape (Bi-Laminate (Alum+Poly), 100% coverage) with a 24 AWG (7x32) TC drain wire for noise rejection.
- Foam FEP - Fluorinated Ethylene Propylene insulation with Western Electric Standard color code.
- Flamarrest® plenum-rated jacket for Indoor - Plenum installations.
- UL voltage rating: 300 V (CMP).
Belden 82729 877 Applications
- Designed for Indoor - Plenum installations where plenum fire performance and low-smoke requirements are critical.
- Supports RS-232 extended distance applications in computer communication links.
