Removes the need for additional external amplifiers by providing a sufficient analogue voltage output.
Low profile design
The sensor is extremely compact with an overall height of just 24.5 mm and features a large contact area with anti-slip surface.
Stable temperature compensation
Can be used in environments between -10°C and 40°C, with consistent readings even when the temperature fluctuates.
Low sensitivity to off-centre loads
The anti-slip spherical loading surface minimises the effects of off-axis loading, ensuring consistent and reliable test results every single time.
Easy installation
Supplied with a universal mounting bracket, the sensor is easy to install on accelerator, brake and clutch pedals in almost any vehicle, and is also easy to remove.
Brake testing to SAE & ECE standards
Measure the amount of force applied to a brake pedal, as per SAE J2909 (Brake testing) and ECE R13H (Brake Assist Systems) standards.
Need to measure pedal application and force?
Well now you can, with just one sensor. The VBOX Pedal Force Event Marker Interface connects inline between the Pedal Force Sensor and VBOX 3i data logger, triggering the start of a brake test as soon as any pressure is detected.
The Pedal Force Event Marker Interface
As soon as any pressure is applied to the brake pedal, the interface outputs a digital signal, which can be used to trigger the start of a test. It works in a similar way to a traditional brake pedal trigger, but also allows for the measurement of pedal force and does not need to be stuck to the pedal. Instead, it can be placed next to the VBOX 3i that it is connected to, or securely inside the VBOX carry case.
This gives you a complete solution which measures the amount of force applied to a brake pedal, as well as pedal application, in accordance with SAE J2909 (Braking) and ECE R13H (Braking Assist Systems) regulations.
The VBOX Pedal Force Event Marker Interface constantly monitors the pedal force sensor voltage and adjusts the trigger threshold. This accounts for any fluctuations in pedal force caused by changes in temperature of the sensor itself, preventing incorrect trigger activation.
*The pedal force transducer has a zero load output of approximately 0.1 Volts

The pedal force event marker interface is not designed to be connected directly to vehicle power. It connects to a VBOX 3i and gets power from this, as it requires theVBOX 3i power input protection.
Want to learn more about brake testing? The VBOX 3i GNSS data logger is the industry standard, thanks to its impressive accuracy and range of features along with an attractive price point.
It also comes with free data analysis software with dedicated brake test plugins, making it quick and easy for you to test in real-time.
