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.
Sensor types:
End-of-shaft contactless sensor
- Traditional magnetic Hall effect design
- Drop-in contactless alternative to potentiometers
- Fly leads or integrated connectors
Through-shaft contactless sensor
- Magnetic Hall effect with single and multi-turn outputs
- Through or hollow-shaft mechanical design wraps around any shaft, delivering position data directly from source
