Long cable terminals (x20)

Long Brass Cable Terminals: Precision in Every Electrical Connection

When the wiring of a slot car or a model electrical installation fails, it is rarely the fault of the cable itself: the problem almost always lies at the ends. These long cable terminals made of brass, with a 1.5 mm diameter and 4.4 mm total length, are designed to ensure a clean, secure, and durable connection where it matters most.

The reference SP108011 comes in a pack of 20 units, allowing for stock replenishment for successive preparations or to equip several cars in the same workshop session.

Main Features

• Material: brass, resistant to oxidation and with excellent electrical conductivity.
• Diameter: 1.5 mm.
• Total Length: 4.4 mm.
• Contents: bag with 20 units.
• Reference: SP108011.

Function and Performance

A well-finished terminal prevents micro-cuts in current that translate on track into unexpected speed losses or erratic motor behaviour. Brass offers the ideal combination of malleability for precise crimping and conductivity to ensure that the electrical signal reaches the motor intact from the braid.

The long format (4.4 mm) facilitates work in tight spaces — such as resin chassis or very tight bodies — where standard terminals are difficult to handle with pliers.

Compatibility and Applications

These terminals are for general use and adapt to any project that works with cable of a section compatible with a 1.5 mm diameter terminal. They are especially useful in:

• Wiring of motors in slot cars for preparation or competition.
• Connections of braids and pickup shoes.
• Electrical installations in static models with LED lighting.
• Dioramas with lighting or motorisation elements.
• Any modelling project where a reliable cable termination is required.

Assembly and Preparation

For an optimal result, strip the cable just enough so that the copper wire fits snugly to the bottom of the terminal without protruding. A crimping with the appropriate tool — fine-tipped crimping pliers — and, if greater security is desired, a small solder point, ensure a joint that withstands the vibrations typical of track competition.

Common Mistakes

• Stripping too much cable: excess exposed wire can cause short circuits in metal chassis.
• Not checking the crimp: gently pulling on the cable after crimping confirms that the terminal does not give way.
• Mixing incompatible cable sections: ensure that the cable diameter matches the terminal gauge to avoid loose connections.

Frequently Asked Questions

What cable gauge are these terminals designed for?

They are designed for cables whose section is compatible with a terminal of 1.5 mm diameter. If you have doubts about the exact gauge of your cable, measure the total diameter of the copper wire (without insulation) before choosing the terminal.

Is it necessary to solder the terminal in addition to crimping it?

In recreational applications, a good crimp is usually sufficient. For club competition or demanding preparations, adding a solder point increases reliability and reduces the electrical resistance of the joint.

Can they be used in LED lighting installations for models or dioramas?

Yes. As long as the diameter of the cable used in your installation is compatible, these brass terminals work perfectly in low-voltage circuits such as LED lighting.

Is 20 units enough to equip several cars?

It depends on each project, but in a standard slot car preparation, between 2 and 4 terminals are used per vehicle, so the bag of 20 units comfortably covers between 5 and 10 basic preparations.

Does brass oxidise over time?

Brass is significantly more resistant to oxidation than carbon steel. Stored in a dry place protected from moisture, it maintains its conductivity properties for a long time without the need for additional treatments.

The SP108011 long brass cable terminals (1.5 mm diameter × 4.4 mm length, 20-unit bag) are an essential workshop consumable for slot car builders, static modellers and diorama enthusiasts who demand reliable, low-resistance electrical connections. Compatible with standard slot car wiring, motor connections and LED lighting setups, these crimp terminals deliver consistent performance whether you're building a competition-ready slot car or wiring a detailed scale model diorama.
