Open connector for controllers

Connections in view, no surprises during the race session

The open connector for controllers (ref. SP138701) is a preparation accessory designed for those who pay attention to every detail of their slot car controller wiring. Its open design allows visibility of the connection status at any time, avoiding surprises during a club session or at home.

Features and composition

• Materials: fibre and metal, a strong and lightweight combination.
• 3 x 4 mm bananas with M3×3 allen screw for secure and precise tightening.
• 2 cable ties included to organise and secure the wiring neatly.
• Presentation: bag with 1 unit.

Function and advantages in the workshop

One of the most common causes of performance loss in a controller is poor contact in the internal connections. With this open connector, the wiring is exposed and accessible, facilitating both visual inspection and quick maintenance or replacement of any component. The 4 mm bananas are the standard in slot electronics, and the M3×3 allen screw ensures a firm tightening without the risk of loosening with use.

Assembly and preparation

Assembly is straightforward: the bananas are inserted into their slots and secured with the allen screw using the appropriate tool (M3). The included cable ties allow for clean organisation of the cable, reducing mechanical stress on the connections. We recommend periodically checking the tightness of the screws, especially if the controller is frequently used in competition.

Ideal for…

• Enthusiasts who prepare or customise their own slot car controllers.
• Club racers who need quick access to connections for checks between heats.
• Technicians and preparers who value having the wiring organised and visible.

Frequently asked questions

What diameter are the included bananas?

The bananas are 4 mm, the standard format in slot electronics and compatible with most cables and connectors on the market.

Is the allen screw already mounted in the bananas?

According to the manufacturer's description, the M3×3 allen screw is part of each banana assembly. Check the contents of the bag upon receipt to verify the assembly status.

How many units does the bag include?

The bag contains 1 unit of the complete connector with its 3 bananas and 2 cable ties.

What are the included cable ties for?

The cable ties allow for organising and securing the cable to the body of the controller, preventing it from being loose and reducing wear from tension on the connections themselves.

What allen key do I need to tighten the screws?

The screws are M3, so you will need a 1.5 mm allen key or the corresponding size depending on the type of head of the included screw. Check with a set of keys before assembly.
