Sensors

The Delphi Non-Contact Rotary Position Sensor converts rotary motion into an electrical signal to help provide control data necessary for major chassis systems and other automotive and non-automotive 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.

Benefits

• High volume manufacturing processes help achieve competitive costs
• Flexible design is adaptable to a wide range of applications
• Non-contact technology eliminates signal loss on high dither 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 the 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:

• Rocks
• Mud
• Salt
• Ice
• Snow

Using sensor inputs like yaw, pitch, and roll, the Delphi Non-Contact Rotary Position Sensor is helping to advance the performance of vehicle dynamics systems such as anti-lock brake systems, drive-by-wire, and vehicle stability enhancement.
