Offering repeatability, accuracy, resolution, linearity and high stability under harsh environment conditions such as vibration, electromagnetic noise, shock, extreme temperatures, dither, moisture or dirt, PIHER has introduced its true hall-effect contactless position sensors. Over the last years the developments in the field of angular positions measurement using a variation of magnetic field amplitude induced by the displacement of a moving magnet has been intensified.
To meet the demands of angular positions measurement, PIHER has developed different product lines covering various mechanical interfaces for rotary postion sensors.
PIHER uses a technology, in combination with the appropriate signal processing, that is only sensitive to the magnetic flux density of a small magnet rotating above or tangential to the IC surface. This allows to decode the absolute rotary (angular) position from 0-360° in a non-contacting way. The output is available between analogue, PWM and serial protocol.
This technology enables the design of high performance non-contacting magnetic rotary position sensors without the limitations of potentiometric solutions (wear, electrical angle).
The main markets served are automotive, off-road, marine and medical.
