Ribbon Cable ALLNET ALL-A-3 40-pin Female/Female Dupont 0.2m

The ALLNET ALL-A-3 40-pin Female/Female Dupont 0.2m ribbon cable is a short, flexible interconnect designed for prototyping and small-scale wiring tasks. With 40 female Dupont connectors on both ends and a 0.2 meter flat ribbon cable, it offers a compact solution for connecting multiple signal lines between modules, development boards, breadboards, and custom electronics assemblies.

Advantages

This ribbon cable provides a compact, space-saving way to route up to 40 parallel signals while maintaining consistent pin order. The female/female Dupont connectors allow direct mating with single-pin male headers commonly found on microcontroller boards and breakout modules. The flat ribbon construction keeps wires aligned for easier tracing and reduces tangling compared with loose jumper wires. Its short length supports tidy layouts and minimal signal path length for prototyping and bench work.

Suitable for

• Connecting development boards (microcontrollers, SBCs) to peripheral modules
• Wiring between breadboards and header pins during prototyping
• Linking GPIO, address/data buses, and multi-signal interfaces
• Temporary or semi-permanent internal wiring inside enclosures or test fixtures

Key specifications

• Connector type: 40-pin female Dupont on both ends
• Cable type: flat ribbon cable
• Length: 0.2 m
• Contact orientation: straight through, 1:1 pin mapping
• Number of conductors: 40

How to use

Align the female Dupont connectors with the male header pins on the devices or modules you want to interconnect, ensuring correct pin orientation and ordering. Press the connectors gently onto the headers until fully seated. If needed, verify continuity or pin mapping with a multimeter before applying power. For breadboard use, route the ribbon so that each female contact engages the corresponding male pin row. Avoid sharp bends or excessive pulling to prevent damage to the insulation or contacts.

Usage recommendations

For reliable connections, ensure headers are clean and straight and avoid inserting the cable at an angle. Use strain relief or cable clips if the cable will be moved frequently or subjected to mechanical stress. For environments with higher electrical noise or longer runs, consider using individually shielded or twisted-pair wiring instead of flat ribbon cable.
