Methods and systems for a rotary contactless potentiometer device, which includes one or more sensors, such as a Hall Effect sensor. The sensors are mounted on one or more substrates, such as a printed circuit board (PCB). In examples, each sensor channel is electrically isolated on the substrate. The sensors are arranged within range of a magnetic field, such as from a magnet rotatable about a shaft. The potentiometer device is housed in a frame to reduce stray magnetic interference. L'invention concerne des procédés et des systèmes destinés à un dispositif de potentiomètre sans contact rotatif, qui comprend un ou plusieurs capteur(s), tel qu'un capteur à effet Hall. Les capteurs sont montés sur un ou plusieurs substrat(s), tels qu'une carte de circuit imprimé (PCB). Dans certains exemples, chaque canal de capteur est électriquement isolé sur le substrat. Les capteurs sont placés dans la portée d'un champ magnétique, par exemple depuis un aimant pouvant tourner autour d'un arbre. Le dispositif de potentiomètre est logé dans un cadre de façon à réduire l'interférence magnétique parasite.
