Terminal for electric cable Ø2 x 4 mm.

The right terminal makes the difference between a responsive car and one that fails

In slot racing, the small details of preparation are what separate a solid build from one that causes problems on track. The Ø2 x 4 mm electrical cable terminal SP108050 from Sloting Plus is one of those seemingly minor components that, when well chosen, ensure reliable electrical transmission from the braids to the motor.

Function and performance

This terminal acts as a connection point between the electrical cable and the car's internal circuit. Its main function is to ensure that the current flows continuously and without interruptions, something that any driver—be it club or recreational—directly appreciates in the throttle response.

The diameter of Ø2 x 4 mm defines its specific application: it is designed for a specific size of cable, and adhering to this is not optional. A terminal that is too small will not fit properly; one that is too large will be loose and will lose the necessary grip.

Compatibility and assembly

When selecting the correct terminal, three measurements must be considered that need to fit together within the guide housing:

• The diameter of the terminal itself.
• The thickness of the electrical cable strands.
• The thickness of the braids.

The sum of these three elements must allow the assembly to be inserted into the housing with just the right resistance: firm enough so that it does not come out during the race, but without forcing the plastic of the guide to the point of breaking it. That balance is what makes choosing the correct reference so important.

Common mistakes when choosing a terminal

One of the most common mistakes in the workshop is assuming that any terminal works for any cable. The most common consequences of a poorly sized terminal are:

• The terminal comes out of the housing during the race, causing loss of electrical contact and cuts in the car's response.
• Breakage of the guide housing when trying to force a too bulky assembly into place.
• False contacts due to excessive play, resulting in erratic and unpredictable driving.

Taking a moment to measure and verify before assembly is always the best investment of time.

Frequently asked questions

What does the measurement Ø2 x 4 mm mean for this terminal?

The symbol Ø indicates diameter. In this case, Ø2 refers to the diameter of the terminal itself, while 4 mm corresponds to the length of the connector. These two measurements determine which cables and which housings are compatible with this component.

How do I know if this terminal is suitable for my guide?

You should measure the diameter of the housing hole of your guide and compare it with the sum of the terminal diameter, the thickness of the cable strands, and the thickness of the braids. If that sum fits snugly in the housing, the terminal is the correct one.

Can this terminal be used with any brand of guide?

As long as the guide housing has dimensions compatible with the measurements of this terminal, yes. The important thing is to verify the measurements before assembly, regardless of the brand of the guide.

What happens if the terminal is too loose in the housing?

A terminal with excessive play can move or come out during the race, generating false contacts or total loss of electrical signal. It is one of the most frustrating problems on track because it can be mistaken for a motor or controller failure.

The Sloting Plus SP108050 is a 2x4 mm diameter electrical cable terminal designed for slot car wiring. Choosing the right connector size is essential to ensure a stable electrical connection between the braid and the motor, preventing the terminal from slipping out of the guide housing or causing damage during assembly. A must-have precision spare part for slot car tuning, compatible with multiple guide systems when dimensions match.
