## Summary description

The Kabelmeister JW40-040MM jumper wire features a solid tip design and multicolour options, making it ideal for breadboard projects. With a maximum length of 40 cm, it provides flexibility and ease of use for various electronic applications.

## Long description

The Kabelmeister JW40-040MM jumper wire is a single-core connection lead with a solid tip design and a maximum length of 40 cm. Available in multicolour, it is intended for use with solderless breadboards, prototype boards and general low-voltage electronics where clear visual identification of individual conductors is required. The solid tip offers reliable insertion into breadboard contacts and terminal blocks, while the flexible insulated body simplifies routing inside electronic assemblies.
Advantages
These jumper wires combine a rigid solid conductor for steady contact with colour-coded insulation for quick identification. The 40 cm length provides reach for connections across larger breadboards or between modules. Multicolour insulation reduces wiring errors during prototyping and debugging. The simple construction makes them suitable for repeated insertions and rearrangements in development work.
Suitable for
Prototyping and breadboard circuits
Educational electronics and lab exercises
Connecting modules and sensors in low-voltage projects
Testing and temporary wiring in development setups
Key specifications
Conductor type: solid single-core
Maximum length: 40 cm
Insulation: multicolour PVC or similar flexible insulation
Tip style: solid straight tip for breadboard insertion
Intended voltage/current: low-voltage electronic circuits (typical prototype use)
How to use
Insert the solid tip into the intended breadboard row or terminal point until secure, ensuring correct orientation and colour-coded routing. Route the insulated lead to avoid sharp bends near the tip and to maintain clear separation between signal and power lines. For reliable contact, avoid excessive lateral force on the conductor and replace wires that show visible wear or corrosion. Use standard wire-stripping tools if you need to expose additional conductor length for terminal connections; perform this with the power disconnected.
Usage recommendations
Use multicolour wires to map signals consistently across the project and label connections in documentation. For permanent connections, consider soldering or using appropriately rated connectors; use jumper wires primarily for prototyping, testing and temporary wiring. Keep within low-voltage limits and inspect insulation for damage before each use.
