Overview
The Belden 9L28050 flat ribbon cable is a 100-foot grey, 50-conductor ribbon cable designed for reliable general-purpose electronic interconnect applications. The 9L28050 features tinned copper conductor and a PVC insulator, with standard .050″ (1.27mm) pitch spacing that ensures compatibility with widely-used IDC (Insulation Displacement Connector) termination methods.
Key Features
- 50 conductor, 28 AWG (7×36) tinned copper with PVC insulation
- Grey PVC with red polarity stripe for proper circuit alignment
- Provides reliable mass-termination to standard IDC connectors
- Tear feature design allows easy break-outs
- UL Flame Test VW-1 and CSA FT1 rated; RoHS compliant
- 100-foot length in single H-100 packaging
Technical Specifications
The cable meets strict electrical and mechanical standards for industrial control and electronic assembly environments:
- Rated voltage: 300V RMS
- Operating temperature range: -40°C to 105°C
- Characteristic impedance: 150 Ω (GS), 105 Ω (GSG)
- Insulation resistance: 10 GΩ minimum
- Pitch spacing: 0.050″ (1.27mm)
- Cable length: 100.0 feet (30.48 meters)
Typical Applications
The cable is suited for internal interconnection and internal wiring of electronic equipment, with reliable mass-termination to standard IDC connectors. Common uses include computer peripheral interfaces, industrial control panels, test instrumentation, data acquisition systems, and general-purpose wire harnesses where organized, color-coded ribbon routing improves assembly and troubleshooting.
