Test lead Voltcraft MSL-507 1 m, black/red, 4 mm plug with crocodile clips

Voltcraft MSL-507 test lead, 1 m length, with black and red insulated conductors and 4 mm plug terminated with crocodile clips. Designed for temporary electrical connections during testing, measurement and prototyping, this test lead provides quick clip-on contact to component leads, terminals and wires. The combination of a 4 mm plug and insulated crocodile (alligator) clips enables versatile use on benchtop instruments, multimeters and power supplies while keeping exposed metal surfaces minimized for safer handling.

Advantages

The Voltcraft MSL-507 combines a 1 m flexible cable with color-coded insulation for clear polarity identification and durable crocodile clips for reliable clamping on a range of conductor sizes. The 4 mm plug fits standard laboratory and workshop sockets, allowing fast connection and disconnection. Insulated handles on the clips reduce accidental contact with conductive parts. The product is compact, lightweight and intended for repeated temporary connections in test, measurement and educational environments.

Suitable for

• Bench testing and measurement with multimeters and power supplies
• Electronics troubleshooting and circuit prototyping
• Temporary wiring and quick component connections in workshop and lab
• Educational labs and hands-on training where rapid connections are needed

Key specifications

• Cable length: 1 m
• Colors: black and red insulated conductors
• Connector type: 4 mm plug
• Termination: crocodile (alligator) clips with insulated handles
• Intended use: temporary test and measurement connections

How to use

Insert the 4 mm plug into the appropriate instrument socket or banana jack, observing correct polarity using the black and red color coding. Open the crocodile clip jaws and attach them to the component lead, terminal or wire ensuring a secure mechanical and electrical contact. Avoid placing clips on live exposed conductors where insulation is absent; use appropriate personal protective equipment and follow standard safety procedures when measuring live circuits. After testing, remove the clips and unplug the 4 mm connector, storing the leads to avoid kinks or damage to the insulation.

Usage recommendations

Use the Voltcraft MSL-507 for temporary connections only; do not rely on crocodile clips for permanent wiring. Check that clip jaws make firm contact and that insulation is intact before each use. Avoid exceeding the current or voltage ratings of the connected instruments and follow local safety standards when working with live circuits.
