Magnetic Position Measurement
(Hall-Effect) Explained

When a current flows through a Hall element it provides a voltage across the current flow if a magnetic field acts perpendicular to both. Since this voltage is proportional to the magnetic field strength, a non-contact and absolute angle or displacement measurement can be easily achieved by attaching a position magnet to the moving machine part of the application. The system is insensitive to aging and independent of field strength fluctuations of the magnets.

Both shafted and touchless two-part systems enable single-turn angle measurement up to 360°. High resolution with great dynamic response, large mechanical tolerances and feasibility of customer-specific output options are added benefits of this wear free technology.
