SENSORS

Delphi Non-Contact Rotary Position Sensor
The Delphi Non-Contact Rotary Position Sensor converts rotary
motion into an electrical signal to provide position information to a
closed loop motion control system in automotive and nonautomotive applications.
The Non-Contact Rotary Position Sensor's linear output voltage is
directly proportional to the sensor's angle of rotation. Non-contact
performance is made possible by a variety of technologies that
include the latest linear programmable, fully-integrated Hall effect
and Anisotropic magneto resistive (AMR) technologies.
The three-wire sensor is fully electro-magnetic capability (EMC)
compliant and is fully isolated from external disturbances.

applications
Available mechanical links, arms, and brackets can be easily modified to meet customer requirements

Typical Applications
The Delphi Non-Contact Rotary Position Sensor is ideally suited for detection of road wheel position to
enable closed-loop chassis control. Vehicle suspension travel is measured directly by mounting the sensor
between the chassis and the sprung components.
Other automotive applications include the following:
•
•
•

Pedal position
Transmission gear selection
Adaptive headlight aiming systems

Non-automotive applications include the following:
•
•
•
•

Marine hand throttle position
Inboard/outboard tilt and rotation
Agricultural equipment motion
General industrial equipment

Performance Advantages
The Delphi Non-Contact Rotary Position Sensor was designed to perform in the most demanding
automotive environments, including rocks, mud, salt, ice and snow. It is used in the underside of the world's
hardest working trucks.
