Williams Controls WM-540
Suspended Electronic Accelerator, Robust Design, 3/16″ Steel Plate Lever Available for High Static-Load Requirements.
The Curtiss-Wright (Williams Controls) WM-540 electronic suspended pedal is firewall mounted and designed to provide an electrical signal to an engine control module in response to the operator’s demand for engine power.
The WM-540 is equipped with a Hall effect, non-contact sensor that can be programmed for analog output and/or integrated switches. The electronics are IP67 sealed and highly EMI resistant (SAE J1113). In addition, the unit can be customized with contact or PWM output sensors.
The robust design includes a corrosion-resistant, cast-aluminum housing and a coated-steel mounting bracket. Brackets can be modified to meet different mounting requirements. Standard bent-steel lever rods can accommodate a variety of pedal placements, and a customized 3/16” steel plate lever is available for high static-load requirements.
