Technical Information
KEP Foot Pedal
Overview
Description
The electronic foot pedal is used to drive vehicles equipped with hydrostatic transmissions and/or
electronically-controlled engines. It provides an electrical signal to the engine’s electronics proportional
to the degree of pedal actuation. The electronic foot pedal features a sensor specifically designed forheavy vehicle applications.
Danfoss offers two types of foot pedals: Uni-directional and Bi-directional. The uni-directional uses a
potentiometer sensor and was the first electronic foot pedal introduced by Danfoss in 1993. The new bidirectional type uses Hall effect sensors. Both types of foot pedals are PLUS+1® Compliant.

Operation
Uni-directional model typeThe electronic foot pedal accepts a typical supply voltage of 5 Vdc and varies the output from 10% to
90% of supply through the pedal’s rated angle. Three standard accelerator position sensor models areavailable for vehicle toeboard angles ranging from 0° to 25°. Custom mounting, termination, andelectrical characteristics are available upon factory request.
Bi-directional model typeThe electronic foot pedal contains two independent non-contact transducers (Hall elements). The
transducers are designed to operate at 5 Vdc.

Technical Information
KEP Foot Pedal
Overview
Optional connector
The optional mating electrical connector for the bi-directional model type must be ordered directly froma Packard Electric (Delphi Connection Systems) supplier.

C Caution
The electrical connection may be at risk. Wiring directly to the 6 pin Metri-Pack connector, which is
integral to the sensor, may not provide the flexibility and overall integrity that can otherwise be obtainedby using the Danfoss recommended harness (Danfoss part number 11065878).
