Absolute MT encoders
- Absolute MT encoders detect the rotation of a drive axis over several revolutions.
Absolute ST encoder
- In absolute ST encoders, each angular position is well assigned to a definite position value. This absolute position value is available immediately after system switch-on. Therefore, a reference run is not necessary.
Incremental encoder
- Incremental encoders are dedicated for precise measurement of angle, speed or direction of rotational movements.
Magnetische Absolut-Drehgeber
- Die magnetischen Drehgeber der MAGRES-Familie erzeugen ihre absolute Positionsinformation aufgrund eines Stabmagneten. Das so erzeugte und rotierende magnetische Feld wird von einem Magnetsensor in nahezu perfekte Sinus- und Cosinus-Signale umgewandelt.
Mit einem Interpolator und der Auswerteelektronik entstehen so die absoluten eindeutigen Positionswerte.
Vorteile:
- robuste und kostengünstige Drehgeber
- absolute single-turn und multi-turn Positionswerte
