Dual Signal Linear Potentiometer – HD Linear Sensor for Motorsport
Dual Signal Linear Potentiometer from OBP Motorsport is a robust high-precision sensor developed for motorsport applications and particularly suited for electronic pedal boxes in Drive-By-Wire (DBW) systems where accurate and stable position feedback is critical.
This linear potentiometer is designed to replace mechanical feedback solutions with a far more durable and precise sensor capable of withstanding extreme loads, vibrations, and repeated movements in competition use. The conductive plastic technology ensures very high accuracy, long service life, and consistent signal performance even under harsh conditions.
The sensor operates with two completely independent signal tracks, providing the redundancy and safety required in professional motorsport and performance applications. This makes it ideal for ECU control, DBW throttle systems, and advanced pedal setups where stability and reliability are essential.

Cable & Signal Configuration
Track 1
Red = +V
Black = 0V
Yellow = Signal
Track 2
Brown = +V
Blue = 0V
White = Signal
The output is configured so that Fully Closed = +Vmax and Fully Open = 0V. The signal direction can be reversed by swapping the supply wires within the individual track.
Never apply voltage to the signal wires (yellow/white), as this may damage the sensor.
The potentiometer is compact, lightweight, and built to withstand the vibrations and loads found in motorsport environments. It is specifically developed for precision control in professional vehicles where reliability and accuracy are non-negotiable.
