This document describes the features and characteristics of the .050" Round Conductor Flat Cable produced by 3M Interconnect Solutions Division. The cable features halogen-free insulation, which provides advantages of low smoke (BSS 7238) and low toxicity of combustion gases (NES 713), reducing the risk to firefighters, as well as low corrosivity of combustion gases (pH<6.0), reducing damage to nearby equipment. The cable utilizes 28 AWG stranded conductors on .050 inch pitch, allowing for mass terminations to a broad line of IDC connectors. It is zippable for branching or discrete termination. Please refer to the document for detailed information on the physical insulation material, color, marking standard, electrical parameters, and environmental temperature rating of the cable.
The .050" round conductor flat cable from 3M’s 2010 Series features 28 AWG stranded, tinned copper conductors with halogen‑free polyolefin insulation, offering low smoke and low toxicity in case of fire. The cable is designed for mass terminations to a broad line of IDC connectors and is available in standard roll lengths of 100 ft or 300 ft.
Technical data include a 30 V (USA) / <50 V (EU) voltage rating, insulation resistance greater than 1 × 10⁹ Ω/10 ft, and a temperature range of –40 °C to +105 °C. Ordering information and dimensional tables are provided for various conductor counts and widths.
