KEP Foot Pedal
Overview
Description
Features
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 for
heavy 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.
Uni-directional model type
Potentiometer sensor
•
Meets or exceeds FMVSS-124 requirements
•
Low pivot point eliminates need for external heel rest
•
Controls acceleration and deceleration smoothly
•
Potentiometer mounting location minimizes mounting space requirements and reduces vulnerability
•
to dirt, water, and foreign contaminants
3 pin Weather Pack compatible connector
•
Operation
Bi-directional model type
Hall effect sensors
•
14 ± 2° angular rotation, fore and aft
•
FMVSS 124 and 302 compliant
•
Dual ratiometric Automatic Protection Switching (APS) output
•
This feature provides redundancy
‒
Independent, isolated APS circuits
•
Protected against electrical misconnection
•
6 pin Metri-Pack 150 Series connector directly on the sensor
•
Two 3 pin Weather Pack compatible connector
•
These connectors are used with the recommended cable (reference Schematics of a foot pedal
‒
connected to a PLUS+1 module on page 16)
Non contact sensor
•
Black coated steel base and treadle
•
Chromate conversion module components
•
Uni-directional model type
The 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 are
available for vehicle toeboard angles ranging from 0° to 25°. Custom mounting, termination, and
electrical characteristics are available upon factory request.
Bi-directional model type
The electronic foot pedal contains two independent non-contact transducers (Hall elements). The
transducers are designed to operate at 5 Vdc.

Ordering information
The signal range for each transducer can be configured to match a machine’s requirements. Currently,
two different signal options are offered, reference Technical data, Bi-directional model type on page 8.
Use product description and part numbers for ordering electronic foot pedals. For detailed specifications,
refer to chapters Technical data on page 7; Dimensions on page 9; and Electrical connections on page
13.

Technical Information
KEP Foot Pedal
Overview
Optional connector
The optional mating electrical connector for the bi-directional model type must be ordered directly from
a Packard Electric (Delphi Connection Systems) supplier.
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 obtained
by using the Danfoss recommended harness (Danfoss part number 11065878).
