Williams Controls WM-575 (WCS-400101)

Hall-Effect Rocker Pedal with Position Sensor, 14° ± 2° Angular Rotation, Fore & Aft.

The Williams Controls (Curtiss-Wright) WM-575 (WCS-400101) EFPA (Electronic Floor Pedal Assembly) is designed to provide a signal to the engine fuel control system in response to the driver’s request for engine power. A sensor is employed which provides a voltage proportional to the supplied voltage based on the angular displacement of the treadle.

Applications: Throttle with position sensor 

The design of the WM-575 allows programming of the sensor on the pedal to achieve a highly accurate output. The sensor provides a ratiometric signal that is interpreted by the vehicle controller. The electronics are IP67 sealed and highly EMC resistant (SAE J1113). The Hall Effect Pedal is floor mounted and designed for fore and aft movement. It has a rubber cover for foot traction and is made out of a corrosion resistant coated metal. The product can be customized for side-to-side movement.
