Cable Tecline 71040R 1.27 mm AWG 28, 40 conductors, 30.5 m ribbon cable

Tecline 71040R is a 1.27 mm pitch ribbon cable with AWG 28 conductors, containing 40 parallel wires and supplied in a continuous 30.5 m length. The flat, flexible ribbon format is intended for multi-conductor internal wiring, signal and low-voltage interconnections, and harness assemblies where space-efficient routing and parallel conductor alignment are required. The cable is suitable for use with PCB headers and IDC-style or compatible mass-termination connectors that accept 1.27 mm pitch, and it simplifies assembly when multiple signals must be routed together.

Advantages

The ribbon design ensures consistent conductor spacing and easy parallel routing, reducing the need for individual wire management. AWG 28 conductors provide a balance between flexibility and current-carrying capability for signal and low-voltage applications. A long 30.5 m reel allows uninterrupted runs or multiple cut-to-length segments for harness fabrication. The 1.27 mm pitch is compatible with many compact PCB headers and IDC connector systems, enabling reliable mass terminations and reproducible connector alignment.

Suitable for

• Internal wiring of electronic devices and control panels
• Interconnection of PCB headers and IDC or compatible connectors
• Signal and low-voltage distribution in equipment racks or enclosures
• Custom cable harness assembly and mass termination processes

Key specifications

• Conductor pitch: 1.27 mm
• Conductor size: AWG 28
• Number of conductors: 40
• Total supplied length: 30.5 m
• Cable format: flat ribbon, parallel conductors
• Intended use: signal and low-voltage internal interconnections

How to use

Measure and cut the ribbon cable to the required length for your application, allowing service loops and strain relief as necessary. When terminating, align the conductors with the mating IDC or compatible connector designed for 1.27 mm pitch and follow the connector manufacturer's insertion and crimping procedure to ensure reliable contact. For PCB header connections, confirm pin numbering and orientation before mass termination to prevent wiring errors. Use cable ties, routing channels, or adhesive mounts to secure the ribbon and prevent movement or abrasion inside the assembly.

Recommendations

Avoid exceeding the recommended current and voltage ratings for AWG 28 conductors in low-voltage systems and prevent sharp bends that could stress conductors; maintain bend radii consistent with flexible ribbon cable handling. Store the reel in a dry environment and handle the ribbon to avoid contamination of contact areas prior to termination.
