AiM Sports Throttle Position Sensor - Rotary Potentiometer - 719 4-Pin Male

This sensor measures up to approximately 25mm (1 inch) of linear travel.

This is commonly referred to as a "String Pot" throttle position sensor, since it can be connected to your throttle valve or accelerator pedal with a "string", which will pull the sensor as the throttle is opened. Some prefer this method as the string will break in the event of a sensor malfunction, eliminating the risk of the throttle being stuck wide open.

Please note that there is also a "String Pot" type of sensor, which has its own internal string.
