Magnetic sensor systems are omnipresent, but often go unnoticed. They can be found in cars, production facilities and consumer electronics. They monitor electric current flows contactless, detect movements and positions of objects and play an important role in medical and scientific devices. Magnetic field sensors are versatile and indispensable in many systems. 

At the same time, the demands placed on measuring systems are constantly growing and present new challenges not only for the sensors, but also for the magnets. As a result, complex signal processing, the selection of suitable models and evaluation algorithms and their implementation in circuits or systems are becoming increasingly important. Comprehensive know-how in this area is therefore crucial for the development of reliable magnetic sensor systems.

How we gain more information from your magnetic fields

We ensure the profitable integration of magnetic sensor systems into your overall system by combining our know-how in the development of integrated Hall sensors and magnetic field sensor systems with our expertise in analog IC design.

In concrete terms, this means that we

  • advise you on the feasibility of your ideas and the selection of system components and technologies in the field of magnetic sensor systems,
  • measure and simulate your magnetic fields,
  • develop customer-specific 3D magnetic field sensors for position sensors and current sensors,
  • find solutions for your magnetic field sensor systems based on our previously developed 3D magnetic field sensors and
  • support you with series introduction and small series production.
