Pc Accessories Connectors Pro 100 ft 20-Wire Ribbon Cable - Bulk Spool

In this review the bulk 100-ft spool of 20-wire flat ribbon cable is evaluated for builders and hobbyists who need a reliable supply of pre-spaced multicore wire. The bottom line: this cable is best for anyone assembling custom jumper leads or ribbon harnesses for prototyping and repairs because the standard 1.27 mm pitch and color-coded edge make alignment with insulation displacement connectors straightforward. The review focuses on practical use, compatibility with 2.54 mm style connectors, and how the cable behaves during repeated IDC terminations.

Key Features

• 20 conductors: The 20-wire configuration provides a compact multi-signal run that simplifies routing several signals in parallel without separate wires.
• 100-ft spool: Supplied on a large spool so a single purchase covers many builds and reduces the need for frequent reordering.
• 1.27 mm pitch: The 0.05 in (1.27 mm) center spacing aligns with common IDC connectors to let users quickly form reliable terminations.
• 28 AWG stranded: Stranded 28 AWG conductors balance flexibility and durability for repeated bending and assembly work.
• UL 2651 style: The UL-style construction indicates consistent insulation and flat form factor suitable for neat ribbon harnesses.
• 300V rating: A 300 V maximum rating covers typical low-voltage electronics and internal device wiring safely.

Who It's For

The cable is ideal for electronics hobbyists, small-scale manufacturers, and repair techs who make custom IDC ribbon assemblies or need long runs of identically spaced conductors for internal wiring. It works well when multiple signal lines must remain parallel and organized, for example in breadboard-to-board jumpers or coordinating several sensor lines.

This spool is less suitable for someone who needs single insulated wires in different colors or who requires thicker gauge conductors for high-current applications; for those uses, discrete wire or a heavier gauge cable would be a better choice.

Pros & Cons

Pros

• Long 100-ft spool keeps a steady supply for multiple projects without splicing.
• Standard 1.27 mm pitch and color-coded edge simplify orientation and IDC connector use.
• Stranded 28 AWG offers good flexibility for routing and repeated handling.

Cons

• Twenty conductors on one ribbon limits use where individually colored or thicker wires are required.

Our Verdict

For anyone building custom ribbon harnesses or regularly using IDC connectors, this 20-wire 100-ft spool is a practical, cost-effective choice that saves time and keeps assemblies neat. It provides the right pitch, flexibility, and length for prototyping and small production runs, making it good value for workshop stock.

Frequently Asked Questions

Is this cable compatible with standard IDC connectors?
Yes. The 1.27 mm pitch is the conventional spacing used with many IDC connectors designed for 2.54 mm systems and will align correctly when terminated.

Can this cable carry mains voltage?
No. The cable has a 300 V maximum rating and is intended for low-voltage electronics and internal wiring, not for mains household wiring.

Is the spool sold only in 100 ft lengths?
This listing is for a 100 ft spool; if shorter lengths are required check for per-foot options available from the same supplier.
