Jumper Wire Kabelmeister JW40-040MM-3 3 pcs Solid Tip Multicolour

Kabelmeister JW40-040MM-3 jumper wires are a set of three solid-tip connection leads with a maximum length of 40 cm, designed for prototyping and circuit testing with breadboards and development boards. The multicolour insulation helps identify individual connections quickly during wiring and debugging. These solid-core wires offer stable insertion into breadboard sockets and female headers, supporting temporary and semi-permanent wiring tasks in electronics workbenches, education, and hobby projects.

Advantages

The solid conductor provides reliable contact and reduced movement within breadboard sockets compared to stranded alternatives, while the 40 cm length allows flexible routing across larger breadboards or between nearby modules. Multicolour insulation simplifies circuit tracing and reduces assembly time when working with multiple signals. The set of three wires is compact for small projects and easy to store in toolboxes or component organizers.

Suitable for

• Breadboard prototyping and circuit testing
• Connecting sensors, modules, and development boards
• Educational electronics kits and classroom demonstrations
• Temporary wiring in bench projects and repairs

Key specifications

• Conductor type: solid core wire
• Length: up to 40 cm per wire
• Tip type: straight solid pin suitable for breadboard insertion
• Insulation: multicolour PVC or similar insulating jacket
• Quantity: 3 wires per pack

How to use

Insert the solid tips directly into breadboard holes or compatible female headers, ensuring firm seating to maintain electrical contact. Route the insulated sections to avoid sharp bends and minimize mechanical stress at the entry point. When disconnecting, pull the insulated body rather than the conductor to prevent wire damage. Use the different colours to map signals, power rails, and grounds for easier identification during assembly and troubleshooting.

Usage recommendations

For reliable results, use these solid-tip jumper wires with standard 2.54 mm pitch breadboards and headers. Avoid excessive flexing near the tip and do not apply solder directly to the solid core in the breadboard area. Store the wires coiled without tight kinks to preserve conductor integrity.
