PM controller extension - Sensitivity adjusters (

The PM2070 module from Professor Motor takes your slot controller to the next level thanks to its adjustable sensitivity variators.

Within the electronics catalogue of Professor Motor, the reference PM2070 occupies a very specific place: it is the upgrade that allows you to modify the trigger response curve in compatible controllers. It is not a cosmetic accessory or a generic add-on — it is a tuning tool that directly influences how the movement of your finger translates into power delivered to the motor.

Function and performance

The sensitivity variators of the PM2070 module allow you to adjust the effective travel of the trigger, modifying the progression with which current is delivered to the motor. This has very tangible practical consequences on the track:

• Greater control on corner exits, especially with high-response motors.
• Ability to adapt the controller to different types of circuits, from technical and slow layouts to fast circuits with late braking.
• Finer modulation that reduces errors due to excessive acceleration in delicate sections.

Instead of working with a fixed acceleration curve, the driver can personalise the controller's behaviour according to their preferences and the characteristics of the car they are driving in each session.

Compatibility and installation

The PM2070 is designed as an upgrade for controllers in the Professor Motor range. If you already have a controller from this brand and want to delve into the adjustment possibilities, this module is the direct way to do so without needing to replace the entire unit.

The installation process is typical of a competitive electronics accessory: it requires some familiarity with the internal components of the controller. If you have questions about compatibility with your specific Professor Motor controller model, we recommend consulting us before placing your order.

Ideal for…

• Club racers who compete regularly and need to fine-tune their controller for each session.
• Enthusiasts who have noticed that their current controller does not respond with the progression they need.
• Anyone looking to maximise the capabilities of their Professor Motor electronics without changing controllers.

Points to consider

This product is an upgrade, not a complete controller. It requires a compatible base controller from the Professor Motor range. Before installing it, it is advisable to review the controller documentation to confirm that it supports this specific module.

Frequently asked questions

Is the PM2070 a complete controller or an upgrade?

It is an upgrade. The PM2070 is a sensitivity variator module that integrates into a compatible Professor Motor controller, it is not a standalone controller.

What is the purpose of adjusting the trigger sensitivity?

Adjusting the sensitivity allows you to modify the progression with which power is delivered to the motor. A more progressive trigger facilitates control in corners; a more direct response can favour acceleration in fast sections.

Which Professor Motor controllers is the PM2070 compatible with?

The PM2070 is designed for controllers in the Professor Motor range. If you have questions about whether it is compatible with your specific model, we recommend consulting us before placing your order.

Is it difficult to install?

The installation requires some familiarity with the internal electronics of slot controllers. It is not a plug-and-play operation; it is advisable to follow the manufacturer's instructions or have prior experience handling this type of component.

Can it be used on any type of slot circuit?

Yes. The versatility of the sensitivity variators allows the controller to be adapted to different types of layouts and motors, making it useful on both technical circuits and faster tracks.

The Professor Motor PM2070 sensitivity variator upgrade is a precision electronics module designed for competitive slot car racing. It allows pilots to fine-tune the throttle response curve of their Professor Motor controller, delivering smoother power modulation and better traction control out of corners. A must-have upgrade for club racers looking to optimise their controller performance without replacing the full unit. Compatible with Professor Motor controller range.
