PNI magneto-inductive position sensors. Right on target, every time.

PNI sensors harness the existing power of the Earth's magnetic field to tell you whether you're up or down, on a tilt, or facing east. They're reliable and pinpoint-accurate across a screen or down a ravine; underwater; in space; in a moving vehicle; and at extreme temperatures — all while using up to 10 times less power than other sensor technologies.

Unlike ordinary sensors, which require expensive, time-consuming algorithm development, analog expertise, and integration work, PNI sensors come ready to integrate — with advanced extrapolative tilt calibration for reliability in any environment or application. And every PNI sensor is backed by our knowledge and expertise as the leader in low-power, high-resolution sensor technology.

PNI offers a wide range of position sensors and modules:

  • SmartSens sensor components for small-size, custom integration;
  • CompassPoint Low cost 2-axis and 3 axis digital compass modules for low-power applications;
  • TCM compensated heading and orientation modules for reliable 360° accuracy;
  • SpacePoint motion-based controller technology for consistent, high speed orientation sensing;

Many leading manufacturers use PNI's proprietary magneto-inductive technology in their marquee products across a wide spectrum of applications, including compassing, surveying equipment, sonar, oceanography equipment, motor vehicles, and robotics.
