Curtiss-Wright has launched the WM-G75, a heavy-duty, floor-mounted electronic rocker pedal designed for demanding off-highway applications and as a drop-in electronic replacement for OEMs transitioning from hydraulic to electronic pedal systems.
The WM-G75 uses air as its damping medium to deliver a controlled, repeatable return-to-neutral response across the full operating temperature range. The patented air-damped mechanism is configurable, allowing OEMs to tune the damping rate and pedal forces to suit specific vehicle and operator requirements. Pedal rotation is adjustable from ±9° to ±12°.
Typical applications include travel and throttle pedals on construction, agricultural and material-handling machines where durability and resistance to contamination are priorities.
The pedal features a narrow profile and low pivot point with reduced floor penetration, protecting the flying-lead harness as it exits below the cab floor and easing installation in restricted footwells. The core mechanism can be supplied as a stand-alone unit or adapted to customer treadles, cab floors or hand levers.
Redundant Hall-effect sensors are integrated into the pedal, with electrical outputs configurable as dual APS/APS-IVS analog, dual PWM or CAN J1939. The electronics are based on Curtiss-Wright’s WM-830 sensor platform, which is ISO 13849 PLd capable, supporting functional safety implementation.
The sensor is rated to IP69K and IP68S, with the mechanical assembly rated to IP69K. The pedal is rated for at least 3 million full-stroke cycles and has been tested for high static loads, vibration, shock, dust, salt spray, pressure washing and chemical exposure to common off-highway fluids.
