Jumper wire Alcasa JW40-040MM — solid tip, breadboard lead, 40 cm, 1 pc, multicolour

Alcasa JW40-040MM is a single solid-tip jumper wire designed for use with breadboards and prototyping boards. The rigid single-core conductor and 40 cm length provide a stable, easy-to-route connection between components. The multicolour insulation helps with visual identification of signal paths during circuit assembly and testing.

Advantages

This jumper wire offers a firm, solid tip that inserts cleanly into breadboard contacts and stripboard holes, reducing intermittent connections. The 40 cm length allows flexible placement of components while keeping wiring tidy. Multicolour insulation simplifies tracing and organisation of multiple signal lines. The single-core construction is suitable for reliable temporary connections and straightforward soldering when required.

Suitable for

• Prototyping on solderless breadboards
• Temporary wiring between modules and sensors
• Circuit testing and troubleshooting
• Educational electronics and hobby projects

Key specifications

• Wire type: solid single-core conductor
• Tip style: solid, straight tip for breadboard insertion
• Length: 40 cm
• Quantity: 1 piece
• Insulation: multicolour for easy identification

How to use

Insert the solid tip into the desired breadboard or stripboard hole until it seats firmly. Route the 40 cm lead to the target connection point to maintain a neat layout and avoid crossing sensitive signal lines. For temporary setups, leave wires unaltered; for more permanent connections, consider soldering or using crimped terminals compatible with single-core conductors. Replace any wire that shows signs of corrosion or mechanical damage before use.

Usage recommendations

Use these jumper wires for low-voltage prototyping and testing. Avoid excessive bending near the solid tip to prevent breakage of the conductor. Match colours to signal types (power, ground, data) for clearer circuit documentation.
