The 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 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.

3.0 Description: The Celect ESPA is designed to provide an electrical signal to the engine control module in response to the operator’s demand for engine power. A sensor provides a linear voltage output proportional to the pedal angular displacement. It also provides an independent switched output that closes when the sensor is in the IDLE POSITION and a second output that closes ON THROTTLE ACTIVE.
