6D detection of a cuboid magnet with HallinMotion® using HallinOne® 3D magnetic field sensors

Where movements occur in several degrees of freedom simultaneously, such as in input devices or in robotics, conventional systems for position detection often reach their limits. They can only detect a maximum of two degrees of freedom or are unable to reliably compensate for disturbances caused by lateral movements. Our HallinMotion® technology developed for multi-dimensional position measurement offers a ground-breaking solution here: with its 6D capability, the system enables movements to be measured accurately in all three translational spatial directions as well as rotations around all three axes. This versatility ensures maximum flexibility and allows complex movements to be captured with high precision in a single step. The measuring system, which consists of almost any permanent or electromagnetic arrangement and a magnetic field sensor IC, is extremely robust against temperature fluctuations and external fields. This is particularly valuable in demanding environments, as there is no need for multiple sensors or additional compensation mechanisms - which both saves costs and significantly reduces system complexity and therefore installation space.

Sensor-independent algorithms - maximum freedom of integration

Our positioning algorithms work independently of the magnetic field sensor technology used. Whether Hall, MR or other sensors - we adapt our software precisely to your requirements. The algorithms can also be integrated into existing systems completely decoupled from our own hardware. This allows you to remain flexible - without compromising on accuracy.

Applications: Efficient product development through integrated sensor technology

Modern technologies and automation require ever more precise and efficient position measurements, especially in applications with complex movements. With HallinMotion®, we enable the absolute position determination of an encoder magnet with just one active component - even under extreme conditions. From safety-critical applications in vehicles and machines to micromechanics and high-precision motion monitoring, our solutions increase your measurement accuracy while reducing the need for additional components and enabling completely new control concepts. These include, among others:

  • Control elements for automotive, household appliances as well as construction and agricultural machinery - even in harsh, safety-critical environments
  • Chassis monitoring systems
  • Robotics
  • CAD control systems with high precision
  • Monitoring of high-precision motion sequences down to the micrometer range
  • Micromechanics and tactile sensors
  • Multi-sensor replacement with a single sensor IC
